In Greek mythology, Poemander or Poimandros (Greek, Ancient (to 1453);: Ποίμανδρος) was the son of Chaeresilaus (son of Iasius) and Stratonice. He was also the founder of Tanagra, which he named after the naiad Tanagra, his wife and the daughter of either Aeolus or Asopus. They had two sons, Leucippus and Ephippus, the father of Acestor.[1] Because Tanagra was founded by him, it was called Poemandria.[2]
Poemander was besieged by the Achaeans in a place called Stephon, for having refused to support them in the Trojan war. At night, he managed to escape and began to fortify Poemandria. His fortifications, however, were made fun of by the architect Polycritus, who leaped over the ditch in derision. Poemander, outraged, threw a stone at him, but missed and hit his own son Leucippus instead, who died of the injury. For the murder, in accordance with the law, Poemander had to leave Boeotia, which was not easy for him, since the land of Tanagra had been invaded by the Achaeans; moreover, his mother Stratonice was carried off by Achilles, who also killed his grandson Acestor. But Ephippus, sent by Poemander to beg for aid, brought Achilles, Tlepolemus and Peneleos to his father; they escorted Poemander to Elephenor, who cleansed him for the murder of Leucippus.[3]
