This man's name is Thoas. He is the king of the island of Lemnos. He is hiding in a trunk.
This is how he fled his home island, as women of Lemnos revolted and slaughtered all males.

The trunk drifted all the way to Oinoi. Here Thoas met a nymph and had a son whom he named Sikinos. The island was named after this man, Sikinos, son of Thoas.
