COINAGE OF THE INDO-GREEKS CHALLENGES OF THE ANCIENTS AND THE SOLUTIONS IN THE MODERN WORLD

When Alexander had to leave his conquest of India midway, some of his generals stayed back to rule the conquered north-west India the part which was known as Bactria. These Kings and generals held sway and minted their coins with pure Hellenistic motifs, scripts/legends, and styles. By the middle of the 2nd century BCE, by the inclusion of the Indian script Kharoshthi, Indian elements started appearing and became mainstream. Not only the legend but the weight standard was changed and the Indian standard was adopted. This was the most important change. Problems: The vast sum of Indo-Greek coinage has been unearthed so far but had remained under-studied for more than one reason. As it remains, the problem areas have remained unaddressed and unanswered. This has mainly happened due to the study of coinage in isolation far away from the find spots and devoid of stratigraphy and ignoring local knowledge of the subject. This situation has been aggravated by political turmoil and insulating archaeological finds and records by limiting the access combined with poor local scholarly work or absence of scientific approach due to poor economic conditions and access to modern methods and technology to approach, enhance, and understand the historically very important Indo-Greek coinage. Unfortunately, Indo-Greek coinage study is clubbed with Hellenistic outlook and mostly aggravated by vogue historicity. Scope of Study: This paper highlights challenges in studying Indo-Greek coinage and other factors that have not been addressed and difficulties in the way of scholarly pursuit. A modern tech-driven approach is recommended for addressing the challenges. Scientific Evaluation: A more technology-driven approach to study the Indo- Greek coinage will unravel the mysteries and remove the historical blind spots. Exclusively treating the subject of Indo-Greek coinage and thus providing recognition it deserves as unique, de-bracketed from Hellenistic coinage. Conclusions: The modern technology-driven data management scientifically adopted archaeological exploration and excavation paired with the latest Information Technology tools including the use of social media platforms can be networked effectively to build up a fresh modern repository of findings that will help historians, archaeologists, scholars, students, and numismatists/collectors.

HORSE-RIDER IMAGE ON THE COINS OF THE EASTERN CELTS AND THE CULT OF CELTIC WAR GODDESS

The article deals with the iconography of the Celtic coins which come from the South-Eastern Europe. Main attention is paid to the coins found in the Trans-Carpathian region of Ukraine. The aim of this article is to shed light on symbolism of the Celtic coins, in particular on a horse-rider figure on the reverse of these coins. Research methodology is based on the structuralist approach. The scientific novelty. The author shows how the imagery of the coins was connected to the Celtic religious beliefs and cults. The Celtic issues from the Trans-Carpathian region were derived chiefly from the coins of Philip II and Audoleon. A horse-rider image is present on almost all of the Celtic coins from the Trans-Carpathian area and nearby regions. While on most of coins the rider’s figure is highly schematized, some of them contain a detailed image of a female figure. There is no reason to suggest that the Celtic women used to lead their communities or were widely involved in the warfare as military leaders or individual fighters. At the same time, their significance in the religious and ideological spheres of warfare was great. One can assume that the horse-rider depicted on the Celtic coins was considered rather as an image of deity associated with war, fertility and horse-breeding. It is highly probable that this deity in fact was Epona or other related goddess. The coins were widely used in both trade and ritual practices. In particular, the Classical sources mention the Celtic ritual of devotion of coins to the goddess of hunting. The findings of coins with chop-marks, similar to those found in the Gallic and Gallo-Roman sanctuaries, should be mentioned in this context as well.

CLASSIFICATION OF THE OLBIAN COINS OF THE SECOND HALF OF THE 4TH CENTURY BC.

Since the beginning of the XXI century, the amount of available for the researchers numismatic material has increased significantly, so introducing a new types of coins into the scientific circulation has become an especially relevant in modern numismatics, even when the archaeological context of most of these finds is almost lost. The study of ancient numismatics of Olbia is rapidly gaining in modern Ukraine. At the beginning of the XX century, ancient numismatics already had some significant achievements, but the accumulated material required urgent cataloging and systematization. During last 10 years since the publication of the most important and thorough catalog of ancient coins by Vladlen Opanasovich Anokhin, as well as the results of cataloging Olbia coins by other researchers - Valery Nechitaylo and Grigory Makandarov, numismatics has been enriched by new previously unknown coin types. The aim of the study. The main purpose of the article is to introduce into the scientific circulation new varieties of Olbia coins and to compile the most complete classification of Olbia coins of the IV century BC. Research methodology. In the process of scientific elaboration of the topic general scientific methods were used: analytical, chronological, and topographical, as well as source methods: critical, metrological and iconographic. A systematic approach to the processing of modern finds from private collections and access to the collections of foreign museums was the impetus for writing an expanded classification work. The scientific novelty. The value of the processed materials is that they not only complement this group of coins, but also refine previously published types in unsatisfactory condition, where incorrect reading of the names and trinkets has led to inaccuracies. The Conclusions. The so-called «obol series» covers the period of the Olbia minting around 350-330 BC. The monetary system consists of four denominations: obol (on the coin field depicts Demeter and the eagle on the dolphin), dikhalk (on the coin field depicts Demeter and the eagle on the dolphin), hulk (on the coin field depicts Demeter and the ear, dolphin) and hemihalk (depicts Demeter and dolphin). The die analysis allowed to divide the coins of Olbia of the IV century BC senior denomination for two stylistic groups. According to the results of our own research, we were able to determine the following number of varieties of each of these denominations: obols – 24 types, dikhalks - 6 types, hulks - 6 types, hemihalks - 2 types. We see the prospect of further research in the introduction into scientific circulation of new previously undiscovered varieties of Olbian coins from little-studied sources - materials of museum collections in Ukraine and abroad, among numismatic rarities sold at numismatic auctions and private collections.

THE ANTIKYTHERA WRECK: A NUMISMATIC APPROACH

The paper examines the coins found inside the Antikythera wreck. The wreck of Antikythera was discovered by chance by some sponge fishermen in October 1900, in the northern part of the island of Antikythera. The archaeological excavation of the wreck has allowed the recovery of many finds in marble and bronze, with acquisitions of human skeletons related to the crew of the sunken ship, in addition to the famous “Antikythera mechanism”. Various proposals have been made for the chronology of the shipwreck, as well as the port of departure of the ship, which have been based on literary sources or on the chronology of ceramic finds. As far as coins are concerned, it should be remembered that thirty-six silver coins and some forty bronze coins were recovered in 1976, all corroded and covered by encrustations. The separate study of the two classes of materials, those Aegean and those Sicilian allows to deepen the history of the ship shipwrecked to Antikythera. The treasury of silver coinage is composed of thirty-six silver cistophoric tetradrachms, 32 of which are attributable to the mint of Pergamon and 4 to that of Ephesus. From the chronological point of view, the coins minted in Pergamon have been attributed by scholars to the years from 104/98 B.C. to 76/67 B.C., the date that marks the end of the coinage until 59 B.C. The coins of Ephesus are easier to date because they report the year of issue, even if, in the specimens found, the only legible refers to the year 53, corresponding to our 77/76 B.C., if it is assumed as the beginning of the era of Ephesus its elevation to the capital of the province of Asia in 129 B.C., or 82/81 B.C., if we consider 134/133 B.C., the year of the creation of the Provincia Asiana. As for the three legible bronzes, we note that there are a specimen of Cnidus and two of Ephesus. The coin of the city of Caria was dated by scholars in the second half of the third century B.C. The two bronzes of Ephesus are dated almost unanimously around the middle of the first century B.C., although this fundamental data was never considered for the dating of the shipwreck. The remaining three legible bronzes from Asian mints, two from the Katane mint and one from the Panormos mint, belong to a completely different geographical context, such as Sicily, with its own circulation of coins. The two coins of Katane show a typology with a right-facing head of Dionysus with ivy crown, while on the reverse we find the figures of the Pii Fratres of Katane, Amphinomos and Anapias, with their parents on their shoulders. The specimen of Panormos has on the front the graduated head of Zeus turned to the left, and on the verse the standing figure of a warrior with whole panoply, in the act of offering a libation, with on the left the monogram of the name of the mint. As regards the series of Katane, usually dated to the second century B.C., it should be noted, as, moreover, had already noticed Michael Crawford, that there is an extraordinary similarity between the reverse of these bronzes and that of the issuance of silver denarii in the name of Sextus Pompey, that have on the front the head of the general, facing right, and towards the two brothers from Katane on the sides of a figure of Neptune with an aplustre in his right hand, and the foot resting on the bow of the ship, dated around 40 B.C., during the course of the Bellum siculum. We wonder how it is possible to justify the presence in a wreck of the half of the first century B.C. of two specimens of a very rare series of one hundred and fifty years before, but well known to the engravers of the coins of Sextus Pompey. The only possible answer is that Katane coins have been minted more recently than scholars have established. For the coin series of Panormos, then, it must be kept in mind that there are three different variants of the same type of reverse, for which it is not possible to indicate a relative chronology. In one coin issue, the legend of the ethnic is written in Greek characters all around the warrior; in another coin we have a monogram that can be easily dissolved as an abbreviation of the name of the city of Panormos; in the third, in addition to the same monogram, we find the legend CATO, written in Latin characters. In our opinion, this legend must necessarily refer to the presence in Sicily of Marcus Porcius Cato of Utica, with the charge of propraetor in the year 49 B.C. Drawing the necessary consequences from the in-depth analysis, the data of the Sicilian coins seem to attest to their production towards the middle of the first century B.C., in line with what is obtained from the ceramic material found inside the shipwrecked ship, and from the dating of the coins of Ephesus. The study of numismatic materials and a proposal of more precise dating allows to offer a new chronological data for the sinking of the ship. The presence of rare bronze coins of Sicilian mints suggests that the ship came from a port on the island, most likely from that of Katane.

NEW DATA ABOUT THE HOARDS OF ROMAN COINS FROM THE HRODNA REGION OF THE REPUBLIC OF BELARUS

The article provides information on five new locations of Roman coins from the Hrodna region of the Republic of Belarus: three hoards, as well as two collective finds that can be interpreted as parts of hoards. All of them are represented by denarii of the Roman Empire. Only in one of the deposits – from the village of Bačancy – there is a hybrid barbarian imitation of the imperial denarius. Another of the hoards, found near the village of Varanki, contains, in addition to denarii, fragments of cut silver items, which dates to the beginning of the Migration Period, which makes it possible to determine the date of hiding of this complex in the 5th century. All these finds were made in the course of illegal searches and, unfortunately, only one hoard (Bačancy) almost entirely ended up in the museum collection. The rest of the deposits went to private collections, which hinders their detailed study. Along with new finds in the Hrodna region, there are from 9 to 13 hoards of antique coins. Most of them consist of denarii of the Roman Empire (sometimes along with barbarian imitations). Of the other deposits, the most interesting are the hoard of Roman Republican denarii from under the village of Luckaŭliany, a complex of bronze Alexandrian tetradrachms from under the village of Turec and a hoard (?) of perforated aurei from under the village of Ambileŭcy. Most of the hoards of Roman coins from the Hrodna region can be associated with the East Germans (Pszeworsk and Wielbark archaeological cultures), who penetrated into the Neman River basin inhabited by Baltic tribes in the first half of the 1st millennium AD. It is with the Germans that the vast majority of the hoards of Roman Imperial denarii found on the territory of Barbaricum are associated. It is also possible that some of the hoards could have been deposited by the Balts, which are under powerful East German influence.

ON THE QUESTION OF THE BASIC PERIODIZATION OF IMITATIONS OF THE ROMAN IMPERIAL DENARII IN THE CHERNYAKHIV CULTURE AREA: THE CONCEPT OF TWO «WAVES»

Imitations of Roman coins, the findings of which are very numerous and diverse in Ukraine, have already attracted the attention of researchers. The material accumulated over the last two decades, when taking into account its scale and diversity, allows us to state that imitations of Roman coins in the area of Chernyakhiv culture, is an unique and large-scale phenomenon, visible on the imaginary «map» of ancient numismatics. In this context, the growing number of new findings of imitations actualizes the task of more detailed and meaningful categorization of the accumulated material, in order to create a certain integral «canvas» of such a phenomenon as the imitations of Roman coins from the area of Chernyakhiv culture. The article is devoted to the improvement of the existing typology and periodization of imitations of Roman imperial denarii, which were made in the area of Chernyakhiv culture during the II - IV centuries. To solve this problem, the authors proposed and used an analytical scheme, consisting of a set of classification parameters for the typology of imitations of Roman coins in the area of Chernyakhiv culture. The use of this scheme allowed to form «profiles» and to substantiate the presence in the general set of imitations of two large, non-intersecting groups («waves») of imitations. Further analysis allowed to describe and compare these two «waves» of imitation in more detail. It was found that the first «wave» refers to the period of gradual entry of the Roman silver coins into the area of Chernyakhiv culture (II - early III century), which significantly clarifies the common view, according to which all imitations belong to the second half of the III century or even later. The second «wave» of imitations really refers to the second half of the III - early IV century, as it was established in the literature. Thus, the results of the study substantiated a comprehensive approach to the classification of imitations of Roman coins in the area of Chernyakhiv culture and significantly clarified the chronological framework of their production. In the future, the concept of two «waves» and the analytical scheme proposed by the authors may contribute to a more accurate classification and periodization of the whole array of imitations of Roman coins, which were made in the area of Chernyakhiv culture

HORODNYTSIA TREASURE: VOLODYMYR SVIATOSLAVYCH'S SILVER COINS

The discovery of the Horodnytsia treasure took place in the following graduality. In the evening of 27rd of August 2020 near the village of Horodnytsia, Novohrad-Volynskyi district, Zhytomyr region the local resident Serhii Komar found the treasure of coins of Volodymyr Sviatoslavych (Volodymyr the Great, Volodymyr the Saint) and Sviatopolk Yaropolkovych (“Sviatopolk the Cursed”). The treasure find took place in the forest near the river Sluch while extraction of the sand for household needs. In the morning of 28rd of August the treasure was transferred to the local government authorities – the village council of Horodnytsia according to the Ukrainian law. The expertise of the treasure was carried out at place of find by Dr. Oleksander Alf’orov – the researcher of the Institute of History of Ukraine of the National Academy of Sciences of Ukraine. The treasure consisted of 32 silver coins (sribnyks) inclusively 26 coins of Volodymyr Sviatoslavych and 6 coins of Sviatopolk Yaropolkovych. Next day the group of scientists with the chief of the Zhytomyr Archaeological Expedition of the Institute of Archeology of the National Academy of Sciences of Ukraine, Dr. Andrii Petrauskas and the representative of the Ministry of Culture and Information Policy of Ukraine, the head of the Department of permitting and approval documentation in the branch of the cultural heritage protection – Dr. Bohdan Motsia and the head of the Early Iron Age Archeology department of the National Museum of Ukrainian History – Dr. Serhii Didenko and the research fellow of the Institute of History of the National Academy of Sciences of Ukraine – Dr. Oleksander Alf’orov and the director of the Novohrad-Volynskyi Local Lore Museum – Olena Zhovtyuk and the workmate of the Zhytomyr Archaeological Expedition of the Institute of Archeology of the National Academy of Sciences of Ukraine – Oleksander Minaev. At that place after the professional archeological excavations was discovered the traces of the pit where the treasure was placed. Additionally one more coin and 5 fragments were discovered during the excavation using a metal detector. Thus, on 29th of August 2020, the Horodnytsia treasure numbered 38 coins: 31 sribnyks of Volodymyr the Great (II-IV coin types according to Ivan Tolstoy’s the typological classification), and 7 sribnyks of Sviatopolk Yaropolkovych (all three known coin types). Since the discovery of the Kyiv treasure in 1876, the Horodnytsia treasure is the largest. Analyzing the complex we can suggest that its hoarding took place during the reign of Sviatopolk Yaropolkovych or possibly after his death. Thus, all of the sribnyks of Volodymyr the Great are represent by three of the four types of prince’s issues. Generally speaking, the Type II numbered 6 pieces, Type III numbered 16 pieces and Type IV numbered 9 pieces. And the Type I is absent in the hoard. 10 coins are minted by previously unknown die pairs (in the treasure №№ 10, 11, 12, 14, 16, 20, 21, 32, 34, 38). Additionally interesting are 2 coins with the unknown die combination (in the treasure №№ 15, 22). Their obverses are already published but the reverses are being published for the first time. Thus, 31 sribnyks were investigated and ten of them are minted by previously unknown die pairs and two by unknown die combinations. Since the discovery of the Kyiv treasure in 1876, the Horodnytsia treasure is the largest, as well as one that can be classified as authentic, which is additionally confirmed by the discovery of coins at the place of the treasury find. The unique feature of the Horodnytsia treasure can be considered that the place of its discovery was examined archaeologically: the peculiarities of its topography, conditions of occurrence, stratigraphy and location in the settlement system of the region were revealed. It should be underlined that the treasure was found in the region, where the sribnyks of Volodymyr and Sviatopolk were previously unknown among the coin finds. Unlike the previous finds of sribnyks, the Horodnytsia treasure was not transferred to the private collections abroad, but replenished the museum fund of Ukraine. The further research of the treasure with the use of the newest modern technologies will increase the information potential of this treasure.

MONEY CIRCULATION OF OLBIA PONTIUS AT THE FINAL STAGE OF CITY’S HISTORY

The aim of the study is to explain the unusually high for provincial city percentage of Roman denarii among the coins of ancient Olbia. Research methodology – principles of science, historicism, objectivity, generalization, historical-genetic and historical-typological. Scientific novelty. Some researchers of Olbia connected the final stage of its history with presence of barbarians, carriers of the Chernyakhiv culture (the second third of 3rd – the beginning of 5th c., the dominant population – the Goths). Other researchers believed that the material culture of the city retains its ancient character to the end. Modern analysis of finds from the late Roman layers of Olbia and its surroundings demonstrates undeniable Chernyakhiv analogies and shows the inclusion of the city in political and economic system of barbarians. The truth of this statement can be verified by comparing the numismatic materials of Chernyakhiv culture and Olbia of Roman times. In the area of this culture within the borders of former USSR, finds of more than 26 thousand Roman coins have been recorded. Coins modern to this culture (3rd – 4th c.) are a minority, and 78,7% are represented by earlier silver denarii of the 1st – 2nd c. The barbarians received these denarii from Rome as military contributions and subsidies or wage to military units. Some coins were put into circulation for internal payments. P. Karyshkovsky made statistical calculations of coins of the 1st – 4th c. from Olbia and found some local peculiarity. Unlike other ancient cities of Northern and Western Black Sea coast, among the Roman and provincial coins found in Olbia, the majority are denarii of the 1st – 2nd c.: 53,5% of finds. However, in Histria city (Western Black Sea Coast) denarii make only 17,3%. The peculiarity of Olbia collection can be explained by the history of this city. After the Gothic conquest (between the late 250s and early 270s), Olbia was reborn as small fortified town, a trade and craft center inhabited by Goth barbarians. The distribution of coin finds from the second half of 3rd to the beginning of 5th c. corresponds to the situation in Chernyakhiv culture. Issues of coins of that time came to its population in small quantities. However, the barbarians owned a large mass of old denarii of 1st – 2nd c. Some of them fall into the cultural layer of Olbia, which creates a false picture of money circulation of the city in early Roman times. The percentage of such denarii in Olbia without the participation of the later “Chernyakhiv” addition should be close to the percentage of denarii in Histria (17,3%). Conclusions. A feature of the money circulation of Olbia in Roman times is relatively large number of finds of denarii of the 1st – 2nd c. This can be explained by the fact that in the third quarter of 3rd c. the city was included into political and economic system of Chernyakhiv culture, where the main currency was the silver denarii of the 1st – 2nd c., which by that time were out of circulation in the Empire. The Olbia collection of Roman coins should be divided into the “Ancient” and “Chernyakhiv” (or “Late Antique”) periods, and the latter, in addition to coins of the second half of 3rd – 4th c., contains most of the denarii of the 1st – 2nd c.

HOARD OF ANTONINIANI FROM THE SOUTHERN POBUZHIA

In autumn 2009, 33 whole and 3 fragmented аntoniniani were discovered and collected within the object of the Late Roman Age - Pereginka (Balakiri)2. According to available information, mostly the coins were concentrated in a limited area with sides of about 15 by 10 meters, and only a few ones were spread by plowing equipment at a distance of up to 30 meters. The distribution of coins and the general state of preservation suggests the collected аntoniniani may have been a part of the deposit, which lay at a depth of 25-40 cm, and was made on the day surface due to the use of more powerful attachments that is used in recent years in the cultivation of agricultural land. In the following years, another five whole and three fragmented аntoniniani were found. The total number of discovered coins is 44 copies. Chronologically, the complex is determined by the lower date – 238 A.D. – the issues of Gordian III: «IOVI CONCERVATORI» and «PROVIDENTIA AVG»; and the upper – 251-253 A.D. – the issues of Trebonianus Gallus «PIETAS AVGG» and Voluzian «PAX AVGG». The chronological framework of the complex's emissions is a relatively short period – about 15 years. The complex became the first fixed and attributed deposit of аntoniniani in the forest-steppe zone of South-Eastern Europe and it is extremely important for understanding the processes of formation of Chernyakhiv culture, as well as, further analysis and development of socio-economic relations of the Roman Empire and «Barbarian» communities in the east of the Danube Limes line. At the same time, the limited source base makes no sense to draw any conclusions about the ethnicity or social status of the deposit holder, as well as about possible ways of entering аntoniniani from the complex Perehinka (Balakiri) 2 on the territory of the Ukrainian Forest-Steppe. To receive conditions close to reality it is possible under the condition of detectiono of the closed complex (or its additional inspection) at carrying out full-fledged archeological researches of the given object. Undoubtedly, one can declare working hypotheses: the аntoniniani came here as prey captured by the «barbarians» during the fighting of 247-251 A.D.; or as a part of the ransom payments promised by Trebonianus Gallus to the «barbaric» tribal or military elite. It can be assumed that the аntoniniani belonged to one of the soldiers of the legions stationed in Moesia, who rebelled and joined the coalition of «barbarian» tribes during the «Scythian» wars, we can appeal to the testimony of Zosimus (Zos., I, 28) about a successful campaign of the Roman units in 253 A.D. those were led by Aemilian, during which not only the detachments of «barbarians» led by Kniva were defeated, but also a successful raid was carried out in their land. It is possible to consider assumptions that the complex could be a part of monetary maintenance of the serviceman or the veteran of regular or federal divisions… But – concerning each of the above-stated hypotheses it will be possible to find and express equal argumentation «for» and «against». As with the typology, the deposit is classified as a single-nominal or mixed treasure, as not only denarii but also sesterces and provincial issues are found on the site. We should also pay attention to another key point. The оbject Perehinka (Balakiri) 2, territorially belonging to the upper reaches of the Southern Bug, is located in a region characterized not only by high density and extreme saturation of monuments those belong to the Chernyakhiv culture, but also as one of the main areas its formation. It is here the objects represented by artifacts attesting to their belonging to the early stage of the Chernyakhiv culture are concentrated: Ruzhychanka, Cherneliv-Rusky, Berezhanka, Lepesivka, Luka-Vrublivetska, Chankiv I, and others. If we take into account the chronology of the early stage of Chernyakhiv culture- the so-called «ruzhychanka phase» (according to E. Gorokhovsky) – 230-270 A.D.; the «first phase» (according to I. Bazhan and A. Gay), which are generally synchronized with phase C1 of the Central-European chronological system – 220-260 A.D. – then the complex of аntoniniani from Pereginka (Balakiri)2 can be one of its chronological benchmarks, as an example, and аntoniniani Valerian and Trajan Decius (for Gerenia Etruscilla) in one of the burials of the Chernyakhiv necropolis of Talalayevka (Khrystynivskyi district, Cherkasy region).

THE BURYING OF TREASURES OF «BORYSTHENES» ON THE TERRITORY OF THE OLBIAN CHORA: THE HISTORICAL CONTEXT

The problem of the chronology of the Olbian «Borysthenes» still remains unsolved. To the greatest extent this applies to the date of the cessation of minting of these coins. Analysis of recent research and publications. Thus, according to A. N. Zograf, the last four lightweight groups of «Borysthenes» were minted in the 230 and 220 BC P. O. Karyshkovsky first attributed the completion of the minting of these coins to the 250 BC, later - until 240-230 BC. According to V. A. Anokhin, the minting of «Borysthenes» was completed in 280 BC. E. Ya. Turovsky attributes this event to 270 BC. e., and V. F. Stolba - until 275 BC. Our prosopographic study of differents of the «Borysthenes» of all groups (ie their interpretation by the names of real historical figures on the basis of a synchronized eponymous catalog), confirmed the previously proposed chronology and allowed to obtain a scheme that coincides with the scheme of P. O. Karyshkovsky on the first groups, and according to A. N. Zograf - in the chronology of the last four groups. According to our study, the minting of «Borysthenes» took place from 331-330 BC for at least 110 years with significant breaks; the completion of their issue dates back to 220-218 BC, or even to 217-216 BC. In general, the proposed model, both in terms of chronology and prosopography of coin magistrates, is a result of our basic research platform - synchronized eponymous catalog IPE I2 201 - and is a single interdependent system with lapidary inscriptions, graffiti, legends of agoranoms weights and ceramic inscriptions, magic lists, coin legends, etc. At the same time, the treasures of the «Borysthenes» (which contain, in particular, coins of the later groups) have been published to date, connected with the collapse of the Olbia Chora, and their publishers date no later than 250-240 BC, or even 280 – 275 BC. In other cases, the dating of the treasures is tied to supposedly synchronous (300-275 BC) Pantikapaion coins, which are present together with «Borysthenes». Thus, significant chronological discrepancies were found between the dating of the «Borysthenes» treasures, which have been published in recent years, and the chronological model of minting we have built, which is part of a single chronological and prosopographic system of Olbia IV-I centuries BC. Accordingly, our proposed chronological model requires additional historical justification. The purpose of the paper is to study the chronology and historical circumstances of the collapse of the Right Bank Chora of Olbia in the III century BC, accompanied by a mass burying of the treasures of «Borysthenes». Research methodology – typical scientific methods in combination with the author’s own scientific work by synchronization of the eponyms catalogue IPE I2 201 (calendar) and Olbia’s prosopography, also, comparative paleography. Scientific novelty. On the basis of prosopography and comparative paleography, for the first time, a precision date of issuance of the IPE I2 32 decree in honor of Protogenes, (up to several years), was proposed. The date of the collapse of the Right Bank Chora of Olbia as a result of the invasion of the Scyros & Galatians, which was accompanied by a burying of the treasures of the «Borysthenes», has been clarified. The chronology of minting «Borysthenes», proposed by us in 2014–2020 through the study of their differents on the basis of synchronization of the eponymous catalog IPE I2 201, has been confirmed. Conclusions. 1. The traditional date dominates in science, of the collapse of the Right Bank Chora of Olbia (middle – beginning of the third quarter of the III century BC) established by V.V. Ruban on the basis of the chronological scheme of minting of «Borysthenes» of P. O. Karishkovsky (1968 year). At the same time, there are no other chronological indicators of the collapse of the Olbian Chora in the middle of the III century BC, in addition to the chronology of minting «Borysthenes» by P. O. Karyshkovsky. 2. Leading scholars have linked the demise of the Right Bank Chora to the invasion of the Scyros & Galatians, which is mentioned in decree IPE I2 32 in honor of Protogenes. Even in the time of V.V. Latyshev it is known that this decree is an absolute palaeographic analogue of the wall-building inscription IPE I2 180 of Cleombrot Pantaklus. According to the synchronization of the eponymous catalog IPE I2 201 Cleombrot Pantaclus performed eponymy in 222 BC. Thus, the dating of the decree in honor of Protogenes and the wall-building inscription of Cleombrot Pantaclus near to 222 BC. Both monuments describe the threat of the Scyros-Galatians invasion (inscription IPE I2 180 of Cleombrot Pantaklus – indirectly), which occurred several years later. Our proposed date of cessation of the minting of «Borysthenes» (220-218 BC or even 217-216 BC) for several years precedes the Scyros-Galatian invasion, respectively, in the treasures of «Borysthenes» there are coins and the last groups. Our main conclusion is that the collapse of the Right Bank Chora of Olbia and the hoarding of the treasures of the «Borysthenes» (with the latter groups inclusive) was caused by threat , mentioned in the decree in honor of Protogenes, which realised took place around the middle of the penultimate decade of the III century. BC (not the middle of the III century BC!) invasion of the Scyros-Galatians 3. The existence of treasures formed from «Borysthenes» mainly of the first group, confirms the existence of a chronological break in the minting of the first and second groups. 4. The presence of silver stators of the late IV century. BC as part of the treasure of «Borysthenes» is not a chronological indicator, but only evidence of their circulation until the penultimate decade of the III century BC, (as believe by P.O. Karishkovsky). 5. The presence of coins of Pantikapaion of the end of IV - the first quarter of III century BC in some treasures of «Borysthenes» is not a chronological indicator. These coins were in circulation for at least 250 years until the time of Mithridates VI of Eupator. 6. Finds of «Borysthenes» treasures on the territory or district of a settlement are not unambiguous evidence of the date of their hoarding on the date of collapse of this settlement. In particular, the treasures of the «Borysthenes», hoarded near the crossings (Kapulivka, Ruska Kosa) date near to 215 BC, (not 275 BC, according to their publishers). 7.
