This article reports on developments in archaeological research in North Africa during the last four years, as these are reflected in the 350, or thereabouts, radiocarbon (and thermoluminescence) dates that have appeared since the last review. The number of new dates, and new data, becoming available indicate that North African archaeology is flourishing, although, in contrast to the earlier decades of this century, the focus seems now to be moving toward the eastern part of the region, and toward matters of adaptation rather than of simple classification, as exemplified by the new interpretations of the Dhar Tichitt Neolithic in Mauritania.The lower Nile Valley has yielded evidence for an intensification of subsistence activities in the Late Palaeolithic in two areas, Makhadma and Kubbaniya, both involving fish-harvesting and the latter also witnessing the use of plant-foods on a scale hitherto undocumented for this period.At the beginning of the Holocene, there is now good evidence for an eighth millennium bc Neolithic in northern Niger, complete with sophisticated ceramics, which complements the evidence already known for similar phenomena further east in the Sahara. There is even a possibility that the Khartoum Mesolithic of the central Nile Valley might be equally old. Our understanding of the Sudanese Neolithic has greatly increased. For the first time, there appears to be a development from the Khartoum Mesolithic into the Khartoum Neolithic, albeit located outside the Valley. The Khartoum Neolithic is more or less confined to the fourth millennium bc, but did give rise to the later Kadada Neolithic. After Kadada, the focus of settlement seems to have shifted outside the Valley until Meroitic times.In the protohistoric and historic periods, we have a better understanding of the chronology of the Egyptian Predynastic, although not yet of its development; what models exist will be radically modified if the pyramids are indeed as old as the dates on them now indicate. Finally, far from the Nile Valley in northern Niger, there comes detailed evidence of the development of a precocious metallurgical tradition within a Neolithic context.

This article outlines recent developments in the archaeology of North Africa, and how our views have evolved in the four years since the previous survey. The principal changes, as such, are that in eastern North Africa, for the first time, sties have been found which fall between the Middle and Late Palaeolithic, thus beginning to close a disconcerting gap in the archaeological record; further evidence is available from the eastern and central Sahara that cattle may have been domesticated in North Africa at least as yearly as anywhere else in the world; and we now begin to have a picture of the complex series of local adaptations developed by Neolithic groups along the extreme western edge of the Sahara, which has hitherto been an archaeological vacuum. Research elsewhere in North Africa is devoted to fleshing out our still skeletal view of ways of life in the Late or Epipalaeolithic and, above all, in the Neolithic, when the use of domesticated plants or animals began to have its first effects on human societies. Archaeological research into the historical periods is less active, but parts of the central Sahara may reflect happenings in more active areas to the North, serving as refuges for the series of peoples displaced by the mainstream of history.

A new species of amphipod, Bathyporeia watkini sp. nov. from the Atlantic coasts of North Africa is described. This very characteristic species is abundant in some lagoons and estuaries near 28°N. New morphological information on B. elkaimi d’Udekem d’Acoz and Menioui, 2004 is given after specimens that were recently collected on the Atlantic coasts of southern Spain and South Portugal. The male of B. ledoyeri d’Udekem d’Acoz and Menioui, 2004 is described for the first time and new records of North African B. guilliamsoniana (Bate, 1857) and B. chevreuxi d'Udekem d'Acoz and Vader, 2005a are discussed.

Abstract This article discusses The Met’s unpublished Dalāʾil al-khayrāt—2017.301—(MS New York, TMMA 2017.301), together with a group of comparable manuscripts. The earliest known dated manuscript within the corpus, it introduces several iconographic elements that are new to the Dalāʾil, and which compare with the traditions developing in the Mashriq and the Ottoman world in particular. The article discusses Dalāʾil production in seventeenth-century North Africa and its development in the Ottoman provinces, Tunisia, and/or Algeria. The manuscripts illustrate how an Ottoman visual apparatus—among which the theme of the holy sanctuaries at Mecca and Medina, appearing for the first time in MS New York, TMMA 2017.301—is established for Muhammadan devotion in Maghribī Dalāʾils. The manuscripts belong to the broader historic, social, and artistic contexts of Ottoman North Africa. Our analysis captures the complex dynamics of Ottomanization of the North African provinces of the Ottoman Empire, remaining strongly rooted in their local traditions, while engaging with Ottoman visual idioms.

The first reports on the rock art of north Africa were written in the mid-nineteenth century. Since then, rock art has become a key area of African archaeological research. Commencing with a short background on the environmental setting, this chapter reviews past research and major theoretical perspectives through to the present, highlighting contributions to wider debates. The main geographical, temporal, and archaeological frameworks of north African rock art are summarized in broad chronological order, beginning with late Pleistocene engravings up to ‘Camel art’ of more recent, historical age. Despite current hurdles faced in today’s research environment, rock art studies are of great importance in north Africa, especially when undertaken by African scholars. This precious, irreplaceable, nonrenewable cultural resource is of great educational value, and its preservation, teaching, and dissemination may contribute to a renewed awareness of the cultural value of rock art for future generations.

Abstract Background Elucidation of specific and recurrent/founder pathogenic variants (PVs) in BRCA (BRCA1 and BRCA2) genes can have an impact on breast cancer (BC) and/or ovarian cancer (OC) risk, making genetic testing affordable and accessible. Methods To establish the knowledge about BRCA PVs and to determine the prevalence of the specific and recurrent/founder variants in BRCA genes in BC and/or OC women in North Africa, a systematic review was conducted in Morocco, Algeria, and Tunisia. Results Search of the databases yielded 25 relevant references, including eleven studies in Morocco, five in Algeria, and nine in Tunisia. Overall, 15 studies investigated both BRCA1 and BRCA2 genes, four studies examined the entire coding region of the BRCA1 gene, and six studies in which the analysis was limited to a few BRCA1 and/or BRCA2 exons. Overall, 76 PVs (44 in BRCA1 and 32 in BRCA2) were identified in 196 BC and/or OC patients (129 BRCA1 and 67 BRCA2 carriers). Eighteen of the 76 (23.7%) PVs [10/44 (22.7%) in BRCA1 and 8/32 (25%) in BRCA2] were reported for the first time and considered to be novel PVs. Among those identified as unlikely to be of North African origin, the BRCA1 c.68_69del and BRCA1 c.5266dupC Jewish founder alleles and PVs that have been reported as recurrent/founder variants in European populations (ex: BRCA1 c.181T > G, BRCA1 c1016dupA). The most well characterized PVs are four in BRCA1 gene [c.211dupA (14.7%), c.798_799detTT (14%), c.5266dup (8.5%), c.5309G > T (7.8%), c.3279delC (4.7%)] and one in BRCA2 [c.1310_1313detAAGA (38.9%)]. The c.211dupA and c.5309G > T PVs were identified as specific founder variants in Tunisia and Morocco, accounting for 35.2% (19/54) and 20.4% (10/49) of total established BRCA1 PVs, respectively. c.798_799delTT variant was identified in 14% (18/129) of all BRCA1 North African carriers, suggesting a founder allele. A broad spectrum of recurrent variants including BRCA1 3279delC, BRCA1 c.5266dup and BRCA2 c.1310_1313detAAGA was detected in 42 patients. BRCA1 founder variants explain around 36.4% (47/129) of BC and outnumber BRCA2 founder variants by a ratio of ≈ 3:1. Conclusion Testing BC and/or OC patients for the panel of specific and recurrent/founder PVs might be the most cost-effective molecular diagnosis strategy.

The number of radiocarbon dates relating to Africa has increased rapidly during the last twelve years, as a glance through the back numbers of thisJournalwill show; and the increase reflects quite accurately the growth in our knowledge of later African prehistory. Almost 200 dates are given in this article which have not been quoted before, but even so the list is incomplete. It seems clear that a more and more selective approach will have to be adopted, and perhaps that is a desirable policy in any case. A paper of this kind does not reach a conslusion: it just comes to an end. However, there are some points which deserve particular attention. The thermoluminescence measureents from sites in Cameroun are of interest from a technical point of view, though they seem to be without historical calue. The Dynastic Egyptian dates are important historically as well as technically, and so are the dates from shell middens in Ivory Coast. Indication of contact across the western Sahara during the first millenniumb.c.are reinforced by additional dates for copper mine in Mauritania. One final points is worth repeating. There is evidence, by now amounting almost to proof, that pottery was present in the central Saharan highlands at an earlier date than in the Nile valley or North Africa; and this should affect out ideas about the whole configuration of later African prehistory.

The effect of recent radiocarbon dates from North Africa has largely been to extend the principal phases of prehistory back in time. The Middle Palaeolithic now seems to be essentially beyond the range of the radiocarbon technique, at least in the Eastern part of North Africa, although it may persist later in the West, and, throughout North Africa (with the sole exception of Cyrenaican Libya), there remains a disturbing hiatus between the Middle Palaeolithic and the subsequent Late Palaeolithic bladelet industries. The latter now seem to appear at about 20,000 B.c. over most of non-Saharan, North Africa, and may eventually be found to be earlier. Some of the earliest such occurrences may well be associated with domestication of plants (in Egypt) and of animals (in Algeria). If so, this will necessitate serious reconsideration of our concepts of the ‘Neolithic’. In any case, a true Neolithic appears in parts of the Southern Sahara as early as the eighth millennium B.C., and is widespread in the area by the seventh millennium. Curiously, the beginnings of the Neolithic are much later in the neighbouring and more luxuriant areas (the Nile Valley, the Mediterranean littoral and the Maghreb) than they are in the desert. Less research has been done on the final prehistoric and early historic periods, but, in the North, the invention of the Libyan alphabet and, in the South, the later Iron Age of Chad both seem earlier than had been thought.

Summary An archaeological excavation was carried out at Graham Street, Leith, Edinburgh by Glasgow University Archaeological Research Division (GUARD) as part of the Historic Scotland Human Remains Call-off Contract following the discovery of human remains during machine excavation of a foundation trench for a new housing development. Excavation demonstrated that the burial was that of a young adult male who had been interred in a supine position with his head orientated towards the north. Radiocarbon dates obtained from a right tibia suggest the individual died between the 15th and 17th centuries AD. Little contextual information exists in documentary or cartographic sources to supplement this scant physical evidence. Accordingly, it is difficult to further refine the context of burial, although a possible link with a historically attested siege or a plague cannot be discounted.

The article discusses the results of the latest interdisciplinary research of Czermno stronghold and its immediate surroundings. The site is mentioned in chroniclers’ entries referring to the stronghold Cherven’ (Tale of Bygone Years, first mention under the year 981) and the so-called Cherven’ Towns. Given the scarcity of written records regarding the history of today’s Eastern Poland, Ukraine, and Belarus in the 10th and 11th centuries, recent archaeological research, supported by geoenvironmental analyses and absolute dating, brought a significant qualitative change. In 2014 and 2015, the remains of the oldest rampart of the stronghold were uncovered for the first time. A series of radiocarbon datings allows us to refer the erection of the stronghold to the second half/late 10th century. The results of several years’ interdisciplinary research (2012-2020) introduce qualitatively new data to the issue of the Cherven’ Towns, which both change current considerations and confirm the extraordinary research potential in the archeology of the discussed region.


Medieval Europe was a meeting place for the Christian, Jewish, and Islamic civilizations, and the fertile intellectual exchange of these cultures can be seen in the mathematical developments of the time. This book presents original Latin, Hebrew, and Arabic sources of medieval mathematics, and shows their cross-cultural influences. Most of the Hebrew and Arabic sources appear here in translation for the first time. Readers will discover key mathematical revelations, foundational texts, and sophisticated writings by Latin, Hebrew, and Arabic-speaking mathematicians, including Abner of Burgos's elegant arguments proving results on the conchoid—a curve previously unknown in medieval Europe; Levi ben Gershon's use of mathematical induction in combinatorial proofs; Al-Muʾtaman Ibn Hūd's extensive survey of mathematics, which included proofs of Heron's Theorem and Ceva's Theorem; and Muhyī al-Dīn al-Maghribī's interesting proof of Euclid's parallel postulate. The book includes a general introduction, section introductions, footnotes, and references.
