The relative chronology of the Aegean Iron Age is robust. It is based on minute stylistic changes in the Submycenaean, Protogeometric and Geometric styles and their sub-phases. Yet, the absolute chronology of the time-span between the final stages of Late Helladic IIIC in the late second millennium BCE and the archaic colonization of Italy and Sicily toward the end of the 8th century BCE lacks archaeological contexts that can be directly related to events carrying absolute dates mentioned in Egyptian/Near Eastern historical sources, or to well-dated Egyptian/Near Eastern rulers. The small number of radiocarbon dates available for this time span is not sufficient to establish an absolute chronological sequence. Here we present a new set of short-lived radiocarbon dates from the sites of Lefkandi, Kalapodi and Corinth in Greece. We focus on the crucial transition from the Submycenaean to the Protogeometric periods. This transition is placed in the late 11th century BCE according to the Conventional Aegean Chronology and in the late 12th century BCE according to the High Aegean Chronology. Our results place it in the second half of the 11th century BCE.

The industrial minerals (IM) of antiquity, the ‘earths’ of the Classical sources, have for long eluded the archaeological record because of the limited material evidence they leave behind in the course of their extraction and processing. The extensive references in Classical and medieval literature and travellers' accounts have never previously been followed up by detailed surveys and by scientific analysis. In the course of April–May 1998 archaeological, topographic and geological surveys were carried out at the Roman site of Aghia Kyriaki, on the island of Melos, with the long term aim of putting the elusive ‘earths’ on the archaeological map of ancient industries. The present article outlines the work so far and highlights the complex factors that may contribute to the identification and characterisation of industrial minerals working in the absence of pyrotechnological waste. Furthermore, since IM processing requires a sustainable low temperature energy source, the hypothesis is put forward that Aghia Kyriaki may have been built on agriculturally inhospitable terrain mainly in order to take advantage of the area's still active geothermal field. If proven, this may constitute evidence for the first use of a ‘soft’ and environmentally friendly energy source during the Roman period in the Aegean.

Contexts recently excavated by the BSA in the Roman stoa at Sparta contain pottery dating from the 12th to early 14th centuries. The bulk of the material dates to the first half of the 13th cent., and demonstrates that certain styles of pottery decoration, once considered to be mainly 12th-cent. in date, continue in currency much longer. These contexts show that Champlevé (Morgan's ‘Incised ware’) decorated with animal motives in the tondo are companion pieces of Glaze Painted (Morgan's ‘Green and Brown Painted group V’) and late Slip Painted wares. The descriptively (but confusingly) named ‘Protogeometric’ style of plainware decoration is also one that remains in currency. Cooking-vessels are almost exclusively handmade, in a very coarse fabric evocative of so-called ‘Slavic’ pottery of the 7th cent., with which it may well be confused. Table amphoras (stamnia) and small pithoi are often decorated with a distinctive incised decoration, making handles and body sherds of this usually nondescript and conservative shape particularly identifiable and diagnostic.
