@Letty,
Letty - if those 2 gentlemen are quite finished with their exchange, I want to say I really, really, liked your poem. I'm not sure if this Roman statue really represented Calliope or another muse, Clio, but nobody else seems to know either so this picture should do:
PS I know you said "Grecian" and I'll try to find a Greek one, Roman was the first one to come up.
