Praxiteles

The altar was adorned with the masterly sculptures of Praxiteles, who had, perhaps, selected from the favorite legends of the place the birth of the divine children of Latona, the concealment of Apollo after the slaughter of the Cyclops, and the clemency of Bacchus to the vanquished Amazons.

Upon its surface of bronze were elaborately wrought, in the still exquisite workmanship of Greece, reliefs of the Olympian games; […] they paused motionless, as if suddenly transformed into stone—lifeless, but lifelike, as one of the breathing wonders of Praxiteles.
