2. Of Chios, the instructor of Pantias, and therefore the sixth in that series of seven artists, of whom Aristocles of Sicyon was the first, and Pantias the last. (Paus. 6.9.1; comp. ARISTOCLES). There is some difficulty in fixing the times of these artists; but, on the whole, the most probable date for Sostratus is that assigned to him by Müller, namely, about Ol. 95, B. C. 400. Pausanias (l.c.) only mentions his name, saying nothing of any of his works; but Polybius (4.78) informs us that Sostratus, in conjunction with Hecatodorus, made a bronze statue of Athena, which was dedicated at Aliphera in Arcadia. The name of Hecatodorus does not occur elsewhere; but Pausanias (8.26.4. s. 7) mentions this same statue as the work of Hypatodorus, an artist who flourished between Ol. 90 and Ol. 102, and whose name might easily be corrupted into Hecatodorus. Pausanias does not mention Sostratus in connection with Hypatodorus; and Polybius does not identify him with the teacher of Pantias; but, from a comparison of the two passages with the one first quoted from Pausanias, the inference is at least probable that they refer to the same artist.
