I love the name, and the Goddess has always been depicted beautifully in history--much like the classic depiction of angels, with reddish or gold wings. The sister to Helios, the sun God, before Apollo became the more well-known god of that posistion.
The Greek Aurora, but Eos is a much softer, more classic name for such a deity. I only wish I knew the standard pronunciation for the name, rather than what I'm assuming it is.
But "EE-ohs", according to the last comment, sounds about right.
No, no, no! This name should NEVER be pronounced EE-ohs or EE-aws. The first letter, eta, makes the long "ay" sound. The second, omega, makes the long "oh" sound, and the sigma at the end makes the "s" sound, of course. Therefore, this name is accurately pronounced "AY-ohs."
