The inscription says Glykon won the Nemean games twice in a row. Strasser (2022) argues this is the Heraia, not Nemea.
Date range is taken from Farrington (2012), note 365, with reference to Moretti (1957), no. 725 who in turn references Horace who mentions Philippos Glykon in the first book of his Epistulae (1.1.30). The date is also determined by an epigram featuring Philippos Glykon, to wit Anth. Gr. 7.692, which mentions the athlete's death. Horace's reference and the estimated career of the epigrammatist Antipater of Thessalonike together lead to the estimate of Philippos Glykon's career between 40 and 10 B.C. The place of origin is also taken from Farrington, who refers to Anth. Gr. 7.692, the funeral epigram of Glykon. In the inscription it is said, beside the named victories, Glykon also won in the other 'sacred (and) crown games in Asia, Italia and Hellas.' - PK
