Tereus

Procne, the elder of the two, was married to Tereus of Thrace, a son of Ares, who proved to have inherited all his father’s detestable qualities.

The two had a son, Itys, and when he was five years old Procne, who had all this while been living in Thrace separated from her family, begged Tereus to let her invite her sister Philomela to visit her.

All went well on the voyage, but when they disembarked and started overland for the palace, Tereus told Philomela that he had received news of Procne’s death and he forced her into a pretended marriage.

It seemed that Tereus was safe.

There she saw Philomela, her very face and form, and Tereus equally unmistakable.
