Rhodope (mythology)
In Greek mythology, Rhodope (Ancient Greek: Ῥοδόπη) may refer to two different characters:
Rhodope, one of the 3,000 Oceanids, water-nymph daughters of the Titans Oceanus and his sister-wife Tethys. She was one of the playmates of Persephone in the meadows of Sicily when the latter was abducted by her uncle Hades to be his queen in the underworld. Rhodope, a queen of Thrace and the wife of King Haemus. The latter was vain and haughty and compared himself and Rhodope to Zeus and Hera, who were offended and changed the couple into mountains (the Balkan mountains and Rhodope mountains, respectively). This Rhodope may be one who was called the daughter of Strymon who consorted with Poseidon and became the mother of Athos.
