Anciently, then, the Scythians worshipped their sabres, the Arabs stones, the Persians rivers. And some, belonging to other races still more ancient, set up blocks of wood in conspicuous situations, and erected pillars of stone, which were called Xoana, from the carving of the material of which they were made. The image of Artemis in Icarus was doubtless unwrought wood, and that of the Cithæronian. Here was a felled tree-trunk; and that of the Samian Here, as Aethlius says, was at first a plank, and was afterwards during the government of Proclus carved into human shape. And when the Xoana began to be made in the likeness of men, they got the name of Brete,—a term derived from Brotos (man). In Rome, the historian Varro says that in ancient times the Xoanon of Mars—the idol by which he was worshipped—was a spear, artists not having yet applied themselves to this specious pernicious art; but when art flourished, error increased. That of stones and stocks—and, to speak briefly, of dead matter—you have made images of human form, by which you have produced a counterfeit of piety, and slandered the truth, is now as clear as can be; but such proof as the point may demand must not be declined.
