I was informed about an article, "New Menander mosaics from Antioch" in American Journal of Archaeology, 4 October 2012, Vol. 116. This enabled me to identify pictures.
This is from Menander’s Perikeiromene. The woman to the left is identified as Glykera. The man in the middle the soldier Polemon. The man to the right the attendant, Socias.
