Athena, Goddess of Wisdom

This was an experiment with negatives...
A long time ago in a state far far away (utah) Julia (roguedragon) and I really got into Greek Mythology. We both picked out favorite goddesses. I've always had a deep respect for knowlege and wisdom so Athena's my favorite...in my version of the story, she and her... half brother Hephtetes are like best friends and like to invent stuff together and she and Artemis are just like... twins!! (can you guess who julia's fav goddess is?)
The materials are white paper, black pen and blue pastel pencil.... and some maniping on the computer.... not as great as I hoped but I was going for a Greek Vase look.
Athena (c) ... how can you copyright ancient mythology?
