Coming down to a better authenticated period, it is reported that Lemnos was conquered by Otanes, a general of Darius Hystaspis. But soon (510 BC) it was reconquered by Miltiades the Younger, the tyrant of the Thracian Chersonese. Miltiades later returned to Athens and Lemnos was an Athenian possession until the Macedonian empire absorbed it. By 450 BC, Lemnos was an Athenian cleruchy. The Athenian settlers brought with them Athenian drama, dated to at least 348 BC. However, the tradition of theater seems to date back to the 5th century, and recent excavations at the site Hephaisteia suggest that the theater dated to the late 6th to early 5th century.
