I vaguely remember the motif occurring in approx 4 quite different songs I last heard about 30 years ago. It struck me then as a novel (the first time) and interesting motif and I wondered about its origins. Five years ago I read Fagles' translations of both the Iliad and the Odyssey and discovered the origins of this motif and several others. Ah, the wonders of a classical education!

Fagles' translations are a great read, as are the Introductions and glossaries that go with them.
