"So wisely was medicine managed in Egypt," says Herodotus, "that no doctor was permitted to practise any but his own branch." That is to say, the doctors were all specialists; some treated the eyes, others the teeth, the head, the skin, the stomach, and so forth. The doctors were all priests, and were paid by the Treasury, but they were allowed to take fees besides.
