As then grew the works up, no less stately in size than exquisite in form, the workmen striving to outvie the material and the design with the beauty of their workmanship, yet the most wonderful thing of all was the rapidity of their execution. Undertakings, any one of which singly might have required, they thought, for their completion, several successions and ages of men, were every one of them accomplished in the height and prime of one man's political service. Although they say, too, that Zeuxis once, having heard Agatharchus, the painter, boast of despatching his work with speed and ease, replied, "I take a long time." For ease and speed in doing a thing do not give the work lasting solidity or exactness of beauty; the expenditure of time allowed to a man's pains beforehand for the production of a thing is repaid by way of interest with a vital force for its preservation when once produced. For which reason Pericles's works are especially admired, as having been made quickly, to last long. For every particular piece of his work was immediately, even at that time, for its beauty and elegance, antique; and yet in its vigor and freshness looks to this day as if it were just executed. There is a sort of bloom of newness upon those works of his, preserving them from the touch of time, as if they had some perennial spirit and undying vitality mingled in the composition of them. Phidias had the oversight of all the works, and was surveyor-general, though upon the various portions other great masters and workmen were employed. For Callicrates and Ictinus built the Parthenon; the chapel at Eleusis, where the mysteries were celebrated, was begun by Coroebus, who erected the pillars that stand upon the floor or pavement, and joined them to the architraves; and after his death Metagenes of Xypete added the frieze and the upper line of columns; Xenocles of Cholargus roofed or arched the lantern on the top of the temple of Castor and Pollux; and the long wall, which Socrates says he himself heard Pericles propose to the people, was undertaken by Callicrates. The Odeum, or music-room, which in its interior was full of seats and ranges of pillars, and outside had its roof made to slope and descend from one single point at the top, was constructed, we are told, in imitation of the king of Persia's Pavilion; this likewise by Pericles's order; which Cratinus again, in his comedy called The Thracian Women, made an occasion of raillery,-- So, we see here, Jupiter Long-pate Pericles appear, Since ostracism time he's laid aside his head, And wears the new Odeum in its stead.
