Wikipedia on Wonder Woman:
In most adaptations, Wonder Woman is Princess Diana of the Amazon warrior tribe of Greek mythology. (Note that Diana is the Roman name for the Greek goddess on whom this character is based; Artemis is her Greek name.) The Amazon ambassador to the larger world, she possesses several superhuman abilities and gifts from the Greek Gods, including the Lasso of Truth, created from the Golden Girdle of Gaea and indestructable silver bracelets, formed from the Shield of Aegis. For several years she was described, in the splash page of each story, as being "beautiful as Aphrodite, wise as Athena, swifter than Mercury, and stronger than Hercules."Go here for more.
