Well, Crius was a Titan, Draco a dragon, and Orion was known as "the giant." From what I can tell, they all can't be seen at the same time.
EDIT: Cruis' constellation is Aries. So Aries, Draco, and Orion.
EDIT 2: So I pulled out my star guid app and Aries, Draco, and Orion are pretty much in a straight line across the sky. Don't know how this helps us though.
