¹ Analytical techniques are quoted from IGS Stable Isotope Report No. 49. ‘Carbon and oxygen isotope ratios were determined for the powdered marble samples. Carbon dioxide, produced from about 10 mg of sample by reaction with 100% phosphoric acid in vacuo (McCrea, 1950) was analysed on a V.G. Isotopes Ltd. ‘903’, triple-collector isotope ratio mass-spectrometer. The raw data were corrected for isobaric interferences and instrumental effects in a way similar to those given by Craig (1957) and Deines (1970). The results are given in the usual notation as parts per thousand variation of ¹³C/¹²C and ¹⁸O/¹⁶O ratios from those in the international standard, PDB calcite. The analytical errors (standard error of the mean) are about 0·020% and 0·025% for ¹³C and ¹⁸O respectively.’

³ S.2296 is listed by Giuliano, A., Il Commercio dei sarcofagi attici (Rome, 1962) 316. S.957a, from Xanthos, is not included. S.2296 was analysed by M. Coleman and S. Walker (1979). S.957a has also been analysed and will be published in a British Museum Occasional Paper.Google Scholar

⁴ BM 2324, the sarcophagus found with BM 2296 at Ierapetra, Crete, has an unworked back, but although the decoration of the front and sides is in the Attic style, the lid decorated with laurel leaves is unusual. This sarcophagus is not made of Pentelic marble; the source of its marble is not known, but it may be a Cretan imitation of the Attic type. See Coleman and Walker (1979). This sarcophagus was listed by Giuliano (54, No. 317) and has been compared unfavourably to a sarcophagus excavated at Mallia, N. Crete, with similar, though more ornate decoration (Effenterre, H. van, BCH c (1976), 539).Google Scholar
