Hellespont (3 syl.),
now called the Dardanelles, means the sea of Hell, and was so called because Hell, the sister of Phryxos, was drowned there. She was fleeing with her brother through the air to Colchis on the golden ram to escape from Ino, her mother-in-law, who most cruelly oppressed her, but turning giddy, she fell into the sea.
