Besides the Olympian Jupiter, which no one has ever equalled, Phidias also executed in ivory the erect statue of Minerva, which is in the Parthenon at Athens. He also made in bronze, beside the Amazon above mentioned, a Minerva, of such exquisite beauty, that it received its name from its fine proportions. He also made the Cliduchus, and another Minerva, which Paulus Æmilius dedicated at Rome in the Temple of Fortune of the present day. Also the two statues, draped with the pallium, which Catulus erected in the same temple; and a nude colossal statue. Polycletus of Sicyon,[220] the pupil of Agelades, executed the Diadumenos, the statue of an effeminate youth, and remarkable for having cost one hundred talents; also the statue of a youth full of manly vigor, and called the spear-bearer. In this he made what the artists have called the Model statue, from which, as from a sort of standard, they study the lineaments: so that he, of all men, is thought in one work of art to have exhausted all the resources of art. He also made statues of a man using the body-scraper, and of a naked man challenging to play at dice; as also of two naked boys playing at dice, and known as the Astragalizontes; they are now in the atrium of the Emperor Titus, and it is generally considered, that there can be no work more perfect than this. He also executed a Mercury, which was formerly at Lysimachia; a Hercules seizing his arms, which is now at Rome. Polycletus is generally considered as having attained the highest excellence in statuary, and as having perfected the art, which Phidias invented. A discovery which was entirely his own, was the art of placing statues on one leg. It is remarked, however, by Varro, that his statues are all square-built, and made very much after the same model. Myron of Eleutheræ,[221] who was also the pupil of Agelades, was rendered more particularly famous by his statue of a heifer, celebrated in many well-known lines. He also made the figure of a dog, a Discobolus, a Perseus, the wood-sawyers, a Satyr admiring a flute, and a Minerva, the Delphic Pentathletes,[222] the Pancratiastæ,[223] and a Hercules, which is at the Circus Maximus, in the house of Pompey. Erinna of Teios makes allusion in her poems to a monument which he erected to a cricket and a locust. He also executed the Apollo, which, after being taken from the Ephesians by the Triumvir Antonius, was restored by the Emperor Augustus, from a warning received in a dream. Myron appears to have been the first to give a varied development to his art, having made a greater number of designs than Polycletus, and shown more attention to symmetry. And yet, though he was very accurate in the proportions of his figures, he has neglected to give much expression.
