Haemus

In Greek mythology, King Haemus of Thrace (/ˈhiːməs/; Ancient Greek: Αἷμος, Haîmos) was the son of Boreas. He was vain and haughty and compared himself and his wife, Queen Rhodope, to Zeus and Hera. The gods changed him and his wife into mountains (Haemus Mons and Rhodope Mountains, respectively). In ancient Greek, the Balkan Peninsula was thus known as the "Peninsula of Haemus" (Χερσόνησος τοῦ Αἵμου), a name which retains some currency in modern Greek.
