(Σωσιγένης).
1. An officer who commanded the Phoenician fleet, which had been assembled by Eumenes to make head against his rivals in B. C. 318. The fleet had arrived at Rhosus, where it was detained by contrary winds, when that of Antigonus suddenly arrived, adorned with garlands and other triumphal ornaments, from its recent victory at the Hellespont. Sosigenes himself was on shore, and was unable to restrain the crews, who immediately declared in favour of Antigonus, and joined the hostile fleet. (Polyaen. 4.6.9.)
