Pallas Athena was one of the poetical names given to the Greek goddess Athena (although it's no longer clear what Pallas was supposed to mean), and the original palladium was a statue of Athena that was believed to have the power to protect the ancient city of Troy. When an asteroid belt was discovered between Mars and Jupiter, most of the asteroids were named after figures in Greek mythology, and one of the first to be discovered was named Pallas in 1803. In the same year, scientists isolated a new silvery metal element, which they named palladium in honor of the recently discovered asteroid.
