Due to the high value of some of the materials used and the perishable nature of others, most chryselephantine statues were destroyed during antiquity and the Middle Ages. For example, of the statue of Athena Parthenos, only the hole that held its central wooden support survives today in the floor of her temple. The appearance of the statue is nevertheless known from a number of miniature marble copies discovered in Athens, as well as from a detailed description by Pausanias. Pausanias also described Pheidias' statue of Zeus at Olympia. Here, some of the clay moulds for parts of Zeus's garments made of glass or glass-paste have been discovered in the building known as the "Workshop of Pheidias". They are the only finds directly associated with the great sculptor's most famous works and thus provide useful information on their creation.
