The first great artist of this school was Scopas, born at Paros, and who flourished in the first half of the fourth century B.C. Although famous in architectural sculpture, he excelled in single figures and groups, "combining strength of expression with grace." The celebrated group of Ni'o-be and her children slain by Ar'temis and Apollo, a copy of which is preserved in the museum of Florence, and the statue of the victorious Venus in the Louvre at Paris, are attributed to Scopas. The most esteemed of his works, according to Pliny, was a group representing Achilles conducted to the Island of Leu'ce by sea deities. The only other artist of this school that we will refer to is Praxit'eles, a contemporary of Scopas. He excelled in representing the female figure, his masterpiece being the Cnid'ian Aphrodi'te, a naked statue, in Parian marble, modeled from life, representing Venus just leaving the bath. This statue was afterward taken to Constantinople, where it was burned during the reign of Justinian. This Athenian school of sculpture was followed, in the time of Alexander the Great, by what was called the Si-çy-o'ni-an school, of which Euphra'nor, of Corinth, and Lysip'pus, of Si'çy-on, were the leading representatives. The former was a painter as well as sculptor. His statues were executed in bronze and marble, and were admired for their dignity. Lysippus worked only in bronze, and was the only sculptor that Alexander the Great permitted to represent him in statues. His works were very numerous, including the colossal statue of Jupiter at Tarentum, sixty feet high, several of Hercules, and many others. The succeeding and later Greek sculptors made no attempt to open a new path of design, but they steadily maintained the reputation of the art. Many works of great excellence were produced in Rhodes, Alexandria, Ephesus, and elsewhere in the East. Among these was the famous Colossus, a statue of the sun, designed and executed by Cha'res of Rhodes, that reared its huge form one hundred and five feet in height at the entrance to Rhodes harbor; the Farnese Bull, at Naples, found in the Baths of Caracalla at Rome, also the work of a Rhodian artist; and the Apollo Belvedere, in the Vatican.
