I can't say I like
Odin. It just doesn't have a nice sound.
However, I love
Atlas and
Echo. I don't think they sound stupid or pretentious. Mythology names are becoming more mainstream and I am a sucker for word names.
I have never known an
Atlas but I have known two women named
Echo. One is in her midthirties and the other in her late fifties. They both love their names and get nothing but compliments.
