Edwinus looked up from where he had been making a drawing in the earth with a stick.

"Around 174 A.D. a building to the west of temple, just outside the main sanctuary wall, was pointed out to me and Pausanias as the workshop of Pheidias, where the great statue had been created."

"The archaeological excavations by the German Archaeological Institute in 1958 provided in a dramatic manner that this was correct!"

"Two deposits of debris were found, literally rubbish dumps of material thrown out from this building. They were found to contain tools suitable for work on such a sculpture, discarded cores of ivory, fragments of metal and glass, and there were even terracotta moulds which had been used for the creation of drapery."

"The dumps could be dated to the 430s and later. There can be no doubt that this is the waste material from the workshop that created a 'chryselephantine' sculpture, a statue of gold and ivory, and that that sculpture was the image of Zeus by Pheidias."

Edwinus held up a small object. "As if further confirmation was needed, the base of a broken jug was found, inscribed in careful fifth-century B.C. letters, 'I belong to Pheidias.'"
