Recent research within Mediterranean archaeology has been increasingly concerned with societal responses to past climate changes in the Holocene. In Greek archaeology, such studies have benefited from an increasing volume of palaeoclimatic proxy data that has recently been made available from the Greek mainland. The current review discusses recent debates on climate and society in the ancient Greek world and also provides an overview of proxy records from Greece that have been published in the last 10 years. The paper further presents a focused discussion on the state of the available palaeoclimatological evidence for the first millennium BC. New palaeoclimatological proxy series from lake, marine, and wetland sediments, as well as from speleothem proxy records, provide important data that has been lacking for the Greek mainland in the past. These records provide new, promising avenues for integrative interdisciplinary research focused on human–environment dynamics in different periods of Greek antiquity, but challenges persist in how we can integrate and understand past climate shifts in connection with the archaeological evidence.

This paper addresses the archaeological contexts of the clay moulds used to produce copies of Roman coins in third-century Britain. Previous research has focused primarily upon the technology and chronology of the use of moulds to produce coins with the discarded remains of the used moulds considered as ‘waste’ items from an industrial process. This paper focuses attention on the deposition of the moulds. Using the best-recorded finds, it builds upon earlier suggestions that disused moulds were regularly discarded in boundary locations (settlement boundaries, field boundaries, drainage features, shafts/wells, coastal locations and disused structures). It proposes that the magical and ritual associations of production meant that the clay moulds, in addition to the coins that were produced, required careful handling.

Writing for publication will be central to students’ future careers, so learning this skill should be integral to their graduate training. In a recent graduate seminar, we set up an assignment for which students would write a digital review (DR) and receive periodic feedback on their work through an innovative mock peer-review roundtable workshop. Each student wrote a DR intended for actual publication in the journal Advances in Archaeological Practice. Students worked closely with the instructor and the journal editor on their individual topics, outlines, and abstracts. They also peer-reviewed each other's drafts and discussed their feedback as part of the roundtable workshop, which simulated real reviewers. Finally, each student wrote cover letters and prepared images for submission to the journal. This exercise demystified the peer-review process for students who had little prior knowledge about publication, prepared students for responding to reviewer comments from varying viewpoints, and helped students understand the additional steps involved in publication. Although it was challenging to scale this exercise to a large class, we hope that others will also try and share results from these types of authentic real-world training experiments to advance graduate pedagogy in our discipline and beyond.

Accelerator mass spectrometry (AMS) radiocarbon (14C) dating is central to the development of robust chronologies in archaeological and paleoenvironmental contexts spanning the last 50,000 years. For dates to be accurate, samples must be free of exogenous carbon contamination. At the Oxford Radiocarbon Accelerator Unit (ORAU), considerable advancements in the dating of bone collagen have been made through the development of a high performance liquid chromatography (HPLC) method for the dating of the amino acid hydroxyproline, which can mitigate the effects of carbon contamination. However, recent changes in ligand manufacturing methods for the mixed-mode column used in the ORAU protocol (Primesep A, SIELC Technologies; IL, USA) have resulted in unacceptably high analytical backgrounds. Prior to the manufacturing change, backgrounds of > 50k BP were achievable. Since the manufacturing change, a mean background of 32.5k BP has been measured. Due to column bleed, the Primesep A is therefore no longer suitable for 14C measurement of hydroxyproline from older material. Here, we present background data and the chromatography conditions used to isolate hydroxyproline using an alternative column, a preparative-scale Newcrom AH, which shows promising potential as an alternative for the routine isolation and AMS dating of hydroxyproline—especially approaching the age and mass limits of the method.

We present case studies on three objects of high importance for cultural heritage in southern Poland, dated in years 2018–2022 at the Gliwice 14C and Mass Spectrometry Laboratory with radiocarbon (14C) and dendrochronology methods. The first was a richly ornamented wooden cane, discovered during excavations on the market in Bytom city. The cane can be associated with medieval court proceedings. The archaeological context indicates the 13th century AD, and the 14C result corresponds perfectly with this time, confirming that it is the oldest object of this type in Poland. The second was a 4-m-tall oak column from St. Leonard Church in Lipnica Murowana, a UNESCO heritage site. The local story said it was previously devoted to Światowid, a pagan deity. Our analysis excluded the pre-Christian age, as the tree was felled no earlier than the late 15th century, which is in agreement with historical records. The third was a wooden Saint Lawrence Church in Bobrowniki. The presbytery was covered with up to five layers of polychromic paintings, some of high artistic value. We dated three samples from the original wooden board, and by wiggle-matching, the calibrated age interval was narrowed to 1731–1754 cal AD.

الملح في موريتانيا القيصرية و نوميديا. مصادره؟ استخداماته؟

تواتية عمراوي

هذا هو الملخص الأول للمناطق الوسطى من المغرب العربي (الجزائر) و الذي يظهر الدور الرئيسي الذي لعبه الملح محلياً و كجزء من شبكات تجارية أوسع، و على مدى فترة طويلة من الزمن . اعتمدت هذه الدراسة على مصادر قديمة وحديثة - جغرافية ومعدنية و إثنوغرافية - و تستخدم البيانات الأثرية التي أهمل تحليلها في السابق عن استغلال الملح واستخداماته في العصور القديمة في كل من موريتانيا القيصرية و نوميديا. إن إعادة التقييم هذه تكشف عن مدى توفر الموارد المحلية: حيث كان الملح وفيراً، ويمكن الوصول إليه بسهولة، و يسهل حصاده من البحيرات المالحة أو صخور الملح .

إن البقايا الأثرية التي يتم العثور عليها و بشكل منهجي بالقرب من مكامن الملح الموجودة داخل منطقة المقاطعة الرومانية أو على أطرافها، تؤكد أن السكان استخدموا هذه الموارد المحلية لاحتياجاتهم اليومية. وتظهر الدراسات الإثنوغرافية أن السكان أو القبائل العابرة كانوا - ولا يزالون - قادرين على الاستفادة من الملح المحلي كجزء من تجارتهم مع الشمال والجنوب . تشير أدلة العصور الوسطى إلى أن الملح الصخري من جبل ملح الوطاية (بسكرة) والملح من سبخة آرزيو كان يتم تصديرهما عن طريق البر و من ثم البحر، حيث يصدر الأول لتونس و الثاني لدول أوروبية مجاورة، ولا يوجد ما يتعارض مع حقيقة أن هذا النوع من الشبكات وغيرها كانت موجود بالفعل في العصور القديمة.

This article investigates the utility of a chaîne opératoire approach centered on technologies of ceramic production for identifying Inca mitmaqkuna archaeologically. Although early documents suggest that the Inca program of resettlement (mitmaq) was massive in scale, archaeologists have had minimal success in identifying such relocated populations. Here we test a novel approach that focuses on technologies of production and associated tool assemblages used within different communities of practice. Previous studies indicate that the ethnic Cañari of southern Ecuador used a distinctive method of pottery manufacture involving a specific chaîne opératoire and a unique set of production-related tools. According to early sources, the Inca deported Cañari peoples to various sectors of Tawantinsuyu. In this article, we investigate the contemporary manufacturing style of ceramics from the Ancash region of north-central Peru—an area where Cañari mitmaqkuna were purportedly resettled—to determine whether distinctive communities of practice potentially representing relocated communities might be visible. The results of this study suggest that it is possible to identify connections among distant communities of practice via a focus on craft production technologies that, in certain historical contexts, may be construed as evidence for the presence of resettled populations.
