One more Argonaut must be mentioned, namely, the minstrel Orpheus.  He was the son of the muse Calliope, and was looked on as the first of the many glorious singers of Greece, who taught the noblest and best lessons. His music, when he played on the lyre, was so sweet, that all the animals, both fierce and gentle, came round to hear it; and not only these, but even the trees and rocks gathered round, entranced by the sweetness.
