We have copies also of another Praxitelean original, Apollo Sauroctonos (the Lizard-slayer),[86] but the copyist has evidently exaggerated almost to caricature the elegant slimness of the young god. But on the basis of our knowledge of the Hermes I think we can reconstruct in imagination an exquisite statue even out of the effeminate Vatican copy. The true Apollo would not lean all his weight upon the tree; consequently the tilt of his hips would be less violent. His face would be much more carefully modelled, with less of that womanish smoothness of contour. But the copyist has noted and tried to express the lovely brow which Praxiteles gave to all his heads. The careless grace, the impression of youth and playful strength belong to the original, and are highly characteristic of the artist. The motive of the statue seems to have been a new and rather bold invention; we know of no cult of a lizard-slaying Apollo. It is true that Apollo was the deity commonly invoked in cases of natural plagues, such as invasions of field-mice or locusts, but it seems more probable that Praxiteles, desiring to represent Apollo in a new guise, deliberately chose to portray him as a boy at play. It is clear that Praxiteles was a strongly original and inventive genius, who was not afraid to give his own impression of established types. He was the first who dared to portray Aphrodite naked; out of the gross and bestial Satyr he made a delightful elf of the woods, and he turned the vigorous athlete Apollo into a slender stripling. Of Scopas the Parian, the second great sculptor of the fourth century, we have no important remains. Two mutilated heads found on the site of the temple at Tegea, where he made his great pedimental scene of the Calydonian boar-hunt, indicate the new note of pathos and emotion which he introduced into the carving of the human head. We know that Scopas was engaged on the Mausoleum and on one of the thirty-six sculptured columns of the great temple at Ephesus, but nothing that remains from either of those buildings can be ascribed to him with certainty. Perhaps his most famous work was the Palatine Apollo at Rome. We may get the best notion of his style by studying the head, not the body, of a beautiful statue of Meleager[87] at Rome, which is considered by the most competent archæologists to be a copy of the work of Scopas.
