The Chryselephantine statues, from the middle of the 6th century BC, had wooden cores decorated with ivory for the skin and gold for the hair and clothing. The largest one is perhaps Apollo, the other, his sister Artemis. The third, very damaged by fire, might have been Leto, their mother. Apollo is the statue on the left and Artemis is on the right. This bull, from the later half of the 6th century BC, was made of silver leaf on top of a wooden frame. These two kouroi represent Kleobis and Biton. Herodotus tells us that they are the two pious sons of a priestess of Hera, who pulled their mother's chariot to the sanctuary when the oxen which usually performed the task were late. The goddess Hera rewarded them with the gift of eternal sleep. They date from between 610 and 580 BC.
