Temple of Zeus at Olympia Severe, a Doric temple from the Early Classical period (470-457 B.C.), designed by Libon from Elis.

Pausanias 5.10.3 ff.:
The temple and the image were made for Zeus from spoils, when Pisa was crushed in war by the Eleans, and with Pisa such of the subject peoples as conspired together with her. The image itself was wrought by Pheidias, as is testified by an inscription written under the feet of Zeus: Pheidias, son of Charmides, an Athenian, made me. The temple is in the Doric style, and the outside has columns all around it. It is built of native stone. Its height up to the pediment is sixty-eight feet, its breadth is ninety-five, its length two hundred and thirty. The architect was Libon, a native. The tiles are not of baked earth, but of Pentelic marble cut into the shape of tiles. The invention is said to be that of Byzes of Naxos.
