We have tried to show how savage decorative art supplied the first ideas of patterns which were developed in various ways by the decorative art of advancing civilisation. The same progress might be detected in representative art. Books, like the guide-book to ancient Greece which Pausanias wrote before the glory had quite departed, prove that the Greek temples were museums in which the development of art might be clearly traced. Furthest back in the series of images of gods came things like that large stone which was given to Cronus when he wished to swallow his infant child Zeus, and which he afterwards vomited up with his living progeny. This fetich-stone was preserved at Delphi. Next came wild bulks of beast-headed gods, like the horse-headed Demeter of Phigalia, and it seems possible enough that there was an Artemis with the head of a she-bear. Gradually the bestial characteristics dropped, and there appeared such rude anthropomorphic images of Apollo--more like South Sea idols than the archer prince--as are now preserved in Athens. Next we have the stage of semi-savage realism, which is represented by the metopes of Selinus in Sicily, now in the British Museum, and by not a few gems and pieces of gold work. Greek temples have fallen, and the statues of the gods exist only in scattered fragments. But in the representative collection of casts belonging to the Cambridge Archaeological Museum, one may trace the career of Greek art backwards from Phidias to the rude idol.
