Calliope was the Greek muse for epic poetry, and is most well known as being Homer's muse. So she inspired him to write the Illiad and the Odyssey.

But my mom didn't exactly name me after her. Instead, when I was born I was all pink and screaming and I was LOUD. And a calliope is a type of instrument made out of whistles, and it's really really loud. So I was a Calliope when I was born.

And Callie is a shorter version of that, which I like because Calliope can sound a bit long and old some times. I don't know.
