The ancient Calauria, with which Poros is identified, was given, according to the myth, by Apollo to Poseidon in exchange for Delos; and it became in historic times famous for a temple of the sea-god, which formed the centre of an amphictyony of seven maritime states' - Hermione, Epidaurus, Aegina, Athens, Prasiae, Nauplia, and Orchomenus.
Hermione gives birth to a baby girl, Perdita, who Leontes denounces as illegitimate, and casts her out into the wilderness.
This is an authentic recreation of Hermione's Time Turner as seen in the movie Harry Potter and the prisoner of Azkaban.
It is probable that the island was not dorized before the 9th century B.C. One of the earliest facts known to us in its history is its membership in the League of Calauria, which included, besides Aegina, Athens, the Minyan (Boeotian) Orchomenos, Troezen, Hermione, Nauplia and Prasiae, and was probably an organization of states which were still Mycenaean, for the suppression of the piracy which had sprung up in the Aegean as a result of the decay of the naval supremacy of the Mycenaean princes.
The titles of his tragedies - Achilles, Aegisthus, Equus Trojanus, Hermione, Tereus - are all suggestive of subjects which were treated by the later tragic poets of Rome.
