2. Of Corcyra, the pupil of Critios of Athens (Paus. 6.3.2. s. 5). Pausanias does not mention any work of his, but merely gives his name as one of the following artistic genealogy of teachers and pupils: Critios of Athens, Ptolichus, Amphion, Pison of Calauria, Damocritus of Sicyon. As Critios flourished chiefly about Ol. 75, B. C. 477, we may place Ptolichus about Ol. 83, B. C. 448.
He was therefore a contemporary of Pheidias. [P.S]
William Smith. A Dictionary of Greek and Roman biography and mythology. London. John Murray: printed by Spottiswoode and Co., New-Street Square and Parliament Street. In the article on Soranus, we find: "at this present time (1848)" and this date seems to reflect the dates of works cited. 1873 - probably the printing date.
