Painted Pottery

To date, the pottery production of Rhodes, Kos and other ‘East Dorian’ islands and coastal areas remains little understood. This article presents and discusses new neutron activation analysis (NAA) of eighth–sixth-century bc vessels found on Rhodes and in related areas, placing them in the wider context of past and present archaeometric research. The results highlight the role of Kos as a leading regional centre of painted pottery production and export in the seventh–sixth centuries bc, notably of ‘East Dorian’ plates. This includes the famous ‘Euphorbos plate’, which can now be attributed to Koan production. Contemporary Archaic pottery workshops on Rhodes, in contrast, had a less ambitious, if diverse, output, ranging from vessels in a Sub-Geometric tradition, imitation Corinthian wares and modest local versions of Koan- and Ionian-style plates to finely potted and richly decorated ‘Vroulian’ cups and black-figured situlae. It was imported mainland and East Greek wares, however, that dominated the island's consumption of Archaic painted wares. This represents a departure from the preceding Geometric period, which was characterised by a local pottery production of considerable scale and quality, although receptivity to external influences remained a consistent feature throughout later periods. As patterns of demand were changing, the island's craft production appears to have concentrated on a different range of goods in which high-quality figured finewares played a lesser role.

1. The change in total body calcium content after surgery for primary hyperparathyroidism was studied in seven patients by whole body neutron activation analysis. Three patients who remained in the uncontrolled state for up to 12 months were also studied by this technique. 2. The technique and its reproducibility are described. Changes in total body calcium greater than ±4% should be detectable using this method. 3. The change in total body calcium after surgery was variable. Total body calcium content decreased in three cases after apparently successful parathyroidectomy. Not all the cases experiencing an increase in body calcium content had radiological evidence of bone disease. 4. The role of relative hypoparathyroidism due to suppression of normal parathyroid tissue by a functioning adenoma is discussed.
