Roman goddess of wisdomeand skill of weaving and crafts?

Athena was Goddess of war.

In Rome, he is know as Mars. (and the planets were named after the gods not the other way around.) Though there is a goddess of war in Egyptian mythology. Her name is Sekhmet, usually found as a cat/human, or otherwise just a cat. When I say cat/human I mean the head of a cat and the body of a human, or to be specific, a woman. Then there is also Siva or Shiva, also a war deity. Although he is not a goddess, but a god, an Indian one (not native American, the original Indians, from India.) Anyway, it all depends on which mythology, religion, culture, or philosophy in which you are referring to.
