SIREN, n. One of several musical prodigies famous for a vain attempt to dissuade Odysseus from a life on the ocean wave. Figuratively, any lady of splendid promise, dissembled purpose and disappointing performance. - Ambrose Bierce
The true artist plays mad with his soul, labors at the very lip of the volcano, but remembers and clings to his purpose, which is as strong as the dream. He is not someone possessed, like Cassandra, but a passionate, easily tempted explorer who fully intends to get home again, like Odysseus. - John Gardner
