(Δόκιμος), one of the officers in the Macedonian army, who after the death of Alexander supported the party of Perdiccas. After the death of Perdiccas he united with Attalus and Alcetas, and was taken prisoner together with the former when their combined forces were defeated by Antigonus in Pisidia, B. C. 320. (Diod. 18.45, Polyaen. 4.6.7.) The captives were confined in a strong fort, but, during the expedition of Antigonus against Eumenes, they contrived to overpower their guards, and make themselves masters of the fortress. Docimus, however, having quitted the castle to carry on a negotiation with Stratonice, the wife of Antigonus, was again made prisoner. (Diod. 19.16.) He appears after this to have entered the service of Antigonus, as we find him in 313 B. C. sent by that prince with an army to establish the freedom of the Greek cities in Caria. (Diod. 19.75; Droysen, Hellenismus, vol. i. p. 358.) In the campaign preceding the battle of Ipsus, he held the strong fortress of Synnada in Phrygia in charge for Antigonus, but was induced to surrender it into the hands of Lysimachus. (Diod. 20.107; Paus. 1.8.1.) It is probable that he had been governor of the adjoining district for some time : and he had founded there the city called after him Docimeium. (Steph. Byz. s. v. Δοκίμειον, Droysen, Hellenismus, vol. ii. p. 665; Eckhel, iii. p. 151.) His name is not mentioned after the fall of Antigonus.
