Phthia
Phthia (; Greek: Φθία or Φθίη; transliterations: Fthii [Modern], Phthíē [Ancient]) in ancient Greece was the southernmost region of ancient Thessaly, on both sides of Othrys Mountain and Pharsalus. It was the homeland of the Myrmidones tribe, who took part in the Trojan War under Achilles.
Founded by Aiakos, grandfather of Achilles, it was the home of his father Peleus, his sea-nymph mother Thetis, and his son Neoptolemus, who reigned as king after the Trojan War.
Phthia is referenced in Plato's Crito, where Socrates, in jail and awaiting his execution, relates a dream he has had (43d–44b):
CRITO: It has not arrived yet, but it will, I believe, arrive today, according to a message some men brought from Sunium, where they left it. This makes it obvious that it will come today, and that your life must end tomorrow.
SOCRATES: ...I do not think it will arrive on this coming day, but on the next. I take to witness of this a dream I had a little earlier during this night...I thought that a beautiful and comely woman dressed in white approached me. She called me and said: "Socrates, may you arrive at fertile Phthia on the third day."
