|List of Prosopographies:
I take the dating from Farrington (2012), 147 note 476, based on the firmly dated Olympian victory by Moretti (1957), no. 854 to 137 A.D. (the source gives the Olympiad) and the dating of the inscription (Ivo 217 = IAG 70) by Moretti to ca. 140 A.D. - Farrington goes from here to the proposed date range by assuming a possible career length of ca. 20 years for a herald.
The origin of the athlete is uncertain: it is Laodikeia, Moretti (1957) originally supposed Laodikeia in Phrygia, but Moretti (1987 and 1992) gives thought to a suggestion by Robert which was Laodikeia in Lycaonia, cf. Farrington (2012), 148 note 477 for references. Artemas won many victories, among which supposedly 250 thematikoi agones which are not separately listed here. - PK
