Did You Know?

The sirens were a group of partly human female creatures that lured sailors onto destructive rocks with their singing. Odysseus and his men encountered the sirens on their long journey home from Troy. The only way to sail by them safely was to make oneself deaf to their enchanting song, so Odysseus packed the men's ears with wax, while he himself, ever curious, kept his ears open but had himself tied to the mast to keep from flinging himself into the water or steering his ship toward sure destruction in his desire to see them. A siren today is a sinister but almost irresistible woman. A siren song, however, may be any appeal that lures a person to act against his or her better judgment.
