However, some hot-headed young Athenians were beaten at Coronea by the Bœotians, who were Spartan allies, and a good many small losses befel them by land, till they made another peace for thirty years in 445. There was nobody then in Athens, or Greece either, equal to Pericles, who was managing all affairs in his own city with great wisdom, and making it most beautiful with public buildings.  On the rock of the Acropolis stood the Parthenon, the temple of the virgin goddess Pallas Athene, which was adorned with a portico, the remains of which still stand up gloriously against the blue Grecian sky.  The bas-relief carvings on the pediments, representing the fight between the Centaurs and Lapithæ, are now in the British Museum; and though the statue itself is gone, still seals and gems remain, made to imitate it, and showing the perfect beauty of the ivory and gold statue of Athene herself, which was carved by the great sculptor Phidias, and placed within the temple.  When there was a question whether this figure should be made of marble or of ivory, and Phidias recommended marble as the cheapest, the whole assembly of Athenians voted for ivory.
