I like this name because I am called Atalanta. Kind of upset that others don't like it. In my opinion it's better than a name like Emily or Jane. But that's my opinion.
I think it's a beautiful name, but I quite prefer Atalante (att-uh-LAN-tee). I think it's prettier, flows better, and solves the problem many of you have mentioned of being confused with "Atlanta."
I love how this name sounds, but most people who are not familiar with classical culture (it should be taught more in schools) would probably associate it with 'Atlanta' and (no offense to anyone who lives there!) Atlanta has really no popular historical lore like Savannah or Sidney.
