Information on Holocene glacier variations in Antarctica is limited and sometimes contradictory. However, if the behaviour of the glaciers during the recent past can be clarified, their sensitivity to climatic changes can be evaluated and their contribution to the sea level variation may be predicted. Through the study of local glaciers and floating ice shelves in the Terra Nova Bay area, new information has been gathered. Between 7500 and 5000 yr B.P., after the glacial retreat which followed the Last Glacial Maximum, the Nansen Ice Sheet and the Hells Gate ice shelf were a few kilometres less extensive than they are now. During the second half of the Holocene, both the local glaciers and the ice shelves advanced to positions that were more extensive than their present ones, although not all the variations are adequately dated. A retreat phase of the Edmonson Point glacier occurred during late Middle Ages between 920–1050 A.D. and 1270–1400 A.D. as documented by ten 14C dates obtained from shells in ice-cored moraines. A subsequent advance occurred after the 15th century in a period corresponding to the Little Ice Age.

AbstractVenice is considered the best-informed community of the late Middle Ages. The study examines the availability of information for the second half of the 15th century, particularly with regard to the key year 1462/1463, and as a case study concentrates on areas of the supposed Venetian periphery of interest, above all Hungary and the two principalities of Wallachia and Moldavia. The result is a thoroughly differentiated system of information acquisition, verification and control. Means of communication, as well as different areas of interest of the Serenissima, can be identified. A distinction is made between information maps and communication maps. The latter also include the distribution of news from the lagoon city exchanged with foreign envoys. During the period concerned, news was exchanged in an astonishingly liberal way, in turn integrating the Serenissima into the information networks of the other Italian states. The study thus places the „information commodity“ within the research field of late medieval gift exchange and patronage structures. In short, a thoroughly pragmatic Venetian approach to news acquisition and evaluation can be observed. Verification of the quality of the information obtained was subject not least to quantitative and ranking criteria. Ultimately, the informational power of Venice was based above all on its outstanding reputation among its contemporaries.

In the Middle Ages, people had an ambivalent relationship to the beauty products: some were fully supportive of the attempts to beautify oneself, while the others, first and foremost the representatives of the church, frowned upon this notion. This feature represents a show?case of the advice and recipes for beautification from two medical collections created in the late Middle Ages. These are the Byzantine medical treatise (dating from 11th to 14th century) and the collection of Serbian medieval medicine, the so-called Hodoch Code (dating from the end of the 14th or beginning of the 15th century). The treatise is focusing more on the practical advice than theoretical knowledge, and its greatest part is dedicated to pharmacology. Hodoch Code (Hodoski zbornik) is in fact a therapeutic collection, and it consists of diverse medical texts. These collections contain the advice how to make one?s face white, hair black or blond, but most certainly rich in volume, as well as recipes for treating facial lines, warts, freckles, cracked lips or bad breath.

The paper analyses ceramics and buildings remains of the second half 13th – first half 15th centuries, coming from excavations in Kamianets-Podilskyi. It aims to introduce materials into scientific circulation, to compare the collection with synchronous objects from adjacent territories, to trace interactions in the material culture development in late medieval towns. Ceramics of the Golden Horde and the Grand Duchy of Lithuania times began to be systematically researched relatively recently in Ukraine. Thus, the materials from Kamianets-Podilskyi contribute to deepening our knowledge of less-known periods in the history of Ukraine and Eastern Europe. Materials analyzed were obtained during rescue archaeological research on the Polish Market square in Kamianets. These were fragmented parts of underground and aboveground building structures, as well as a collection of various household items. Building materials were mostly local clays and loam, less often wood and stone were used. A set of clay ‘roll’ blocks set in one of the pits allows us to assume similarity with the Golden Horde building technologies. Finds of coins and Crimean polychrome bowls fragments also indicate the complex emerged during the Golden Horde period. However, certain groups of pottery and coins of European minting define the complex upper date within the first half 15th century. Diverse ceramic types range from the complex is an interesting local typological phenomenon. It reflects mutual influences of the pottery traditions development both in time and space. After processing artefacts collection, the main groups of pottery were identified according to technological features. Some of them are rooted in the local ancient Rus’ traditions, others were formed under the influence of Western trends, while samples of a ‘specific’ group were common for almost the entire territory of modern Ukraine during Late Middle Ages. Pots collection was preliminary systematized up to 5 most common types selection, based on rim profiles. Many of them have a wide range of analogies, locally from Kamianets, as well as from the Western Ukraine, in Poland, Moldova and Romania. In addition to pots, the collection includes other types of kitchen and tableware, such as makitras, lids, jars and other single samples of ceramics. The typological diversity correlates with the multi-layered processes which took place in Kamianets-Podilskyi life during the Golden Horde and the Lithuanian periods. Materials from the complex, as well as other finds from synchronous objects within the city, deepen our understanding of the city’s development large-scale picture, which, however, requires further research.

Abstract. Terra Nova Bay in Antarctica is a formation region for high-salinity shelf water (HSSW), which is a major source of Antarctic Bottom Water. Here, we analyze spatiotemporal salinity variability in Terra Nova Bay with implications for the local HSSW production. The salinity variations in the Drygalski Basin and eastern Terra Nova Bay near Crary Bank in the Ross Sea were investigated by analyzing hydrographic data from instrumented moorings, vessel-based profiles, and available wind and sea-ice products. Near-bed salinity in the eastern Terra Nova Bay (∼660 m) and Drygalski Basin (∼1200 m) increases each year beginning in September. Significant salinity increases (>0.04) were observed in 2016 and 2017, which is likely related to active HSSW formation. According to velocity data at identical depths, the salinity increase from September was primarily due to advection of the HSSW originating from the coastal region of the Nansen Ice Shelf. In addition, we show that HSSW can also be formed locally in the upper water column (<300 m) of the eastern Terra Nova Bay through convection supplied by brine from the surface, which is related to polynya development via winds and ice freezing. While the general consensus is that the salinity of the HSSW was decreasing from 1995 to the late 2000s in the region, the salinity has been increasing since 2016. In 2018, it returned to values comparable to those in the early 2000s.

There is a proposition in palaeoslavistics that the reconstructed prototype of the Izbornik of 1076 is a composition designated as the Kniazheskii Izbornik, which originated from the time of the Bulgarian Tsar Peter (927–969). This article presents an overview of the contents of three manuscripts, which are copies of texts in the so-called Kniazheskii Izbornik: No. 162 from the collection of the Moscow Theological Academy, from the 15th century, Russian origin; No. 189 from the collection of the Hilandar Monastery and which is composed of two parts: Part 1 from the beginning of the 17th century, probably written by a copyist from Moldavia, and Part 2 from 1684, Russian in origin; and No. 280 (333) from the collection of St. Synod of the Romanian Orthodox Church, 15th–16th century, Moldavian in origin. There are suggestions for primary sources of these manuscripts, and the article considers the paths by which texts identical to the Kniazheskii Izbornik found their way into miscellanies in the Late Middle Ages. The three miscellanies under discussion are important witnesses of the paraenetic literature in the earliest period of the Slavia Orthodoxa, which integrated homilies of John Chrysostom, question and answers, interpretations of the Scripture, wise sayings, narration, and apophthegmata from the Paterikon and fragments of the Kniazheskii Izbornik.

This new dataset presents occurrence data for Porifera collected in the Ross Sea, mainly in the Terra Nova Bay area, and curated at the Italian National Antarctic Museum (MNA, section of Genoa). Specimens were collected in 331 different sampling stations at depths ranging from 17 to 1,100 meters in the framework of 17 different Italian Antarctic expeditions funded by the Italian National Antarctic Research Program (PNRA). A total of 807 specimens, belonging to 144 morphospecies (i.e., 95 taxa identified at species level and 49 classified at least at the genus level) is included in the dataset. Nearly half (45%) of the species reported here correspond to species already known for Terra Nova Bay. Out of the remaining 55% previously unknown records, under a third (~29%) were classified at the species level, while over a quarter (~26%) were ascribed to the genus level only and these would require further study. All vouchers are permanently curated at the MNA and are available for study to the scientific community. A 3D model of an uncommon species from the Ross Sea, i.e. Tethyopsisbrondstedi (Burton, 1929), is also presented and will be made available for outreach purposes.

It is noted in the article that the first written information about Podillya towns in Polish sources dates back to the end of the 14th - first half of the 15th century, and in the ancient Old Rus` chronicles there are mentions only of some towns, among which there is Mezhybizh town, located between rivers Pivdennyi Buh and Buzhok. It is stated that the location determined its name. However, it is established that the name Medzhybizh, which has survived to the present day, is fixed in the documents of the late Middle Ages. On the basis of the discovered materials, which are iconographic materials and archival documents of the Sieniawski family, an attempt was made to trace the transformation of the name of the town from the 12th to the 18th century. It is claimed that this name could have been established thanks to beekeeping. It is known that the production and sale of honey and wax played an important role in the economic and financial life of many cities, including Medzhybizh. During the analysis of archival sources, it was established that the document on construction and repair works in the Medzhybizh key for 1727 it is stated that in Nova Syniava a new winter house for beehives was built, which did not exist before, and peasants no longer spent much time and they didn`t drove apiaries to Medzhybozh in the autumn and back to Nova Syniava in the spring. The same clay stebniks were built in Khodkivtsi and Kopystyn, 30 km from Medzhybizh. However, for 10 years in the description of Novosinyavsky court in 1738, the stebnyk on two pillars is marked as old. Only in the document for 1759–1760 was the treasure stebnyk of Medzhybizh first mentioned, in which magnate apiaries were probably kept in winter. We assume that it could be located under the magnate's chambers and rooms in the south-eastern part of the castle of Medzhibizh or near the castle at the court of the Czartoryski, which was surrounded by a moat and an oak fence. Although such an assumption requires thorough research. Also on the map of the geometer Anthony Endrzejowski in 1772 in the explication we find mentions of three large apiaries, which were located near Medzhybizh, on the outskirts of the village Markivtsi. Key words: Medzhybizh, Sieniawski, Czartoryski, stebnyk (a building designed for wintering bees), honey.
