The Thebans used of old to sacrifice bulls to Apollo Spodius: but on one occasion during the festival when the time for the sacrifice drew nigh, and those who had been sent for the bull did not come with it, they sacrificed to the god one of the oxen in a waggon that chanced to be near, and since that time they have sacrificed oxen employed in labour. They also tell this tradition, that Cadmus when travelling from Delphi to Phocis was guided on his journey by a cow which he had purchased from the herds of Pelagon, which had on each side a white mark like the orb of the moon at the full. Cadmus and all the army with him were according to the oracle to make their home where the cow should lie down tired. This spot they show. There in the open air is an altar and statue of Athene, erected they say by Cadmus. To those who think that Cadmus came to Thebes from Egypt and not from Phœnicia this name of Athene affords refutation: for she is called Onga which is a Phœnician word, and not by the Egyptian name Sais. And the Thebans say that the house of Cadmus was originally in that part of the citadel where the market-place now is: and they shew the ruins of the bridal chambers of Harmonia and Semele, this last they do not allow men to enter even to this day. And those Greeks who believe that the Muses sang at the marriage of Harmonia say that this spot in the market-place is where they sang. There is also a tradition that together with the lightning that struck the bridal-chamber of Semele fell a piece of wood from heaven: and Polydorus they say adorned this piece of wood with brass, and called it Dionysus Cadmus. And very near is the statue of Dionysus, made by Onasimedes of brass throughout, the altar was made by the sons of Praxiteles. There is also the statue of Pronomus, a man most attractive as a flute-player. For a long time flute-players had only three kinds of flutes, for some played in the Dorian measure, and other flutes were adapted to the Phrygian and Lydian measures. And Pronomus was the first who saw that flutes were fit for every kind of measure, and was the first to play different measures on the same flute. It is said also that by the appearance of his features and the motion of all his body he gave wonderful pleasure in the theatre, and a processional song of his is extant for the dwellers at Chalcis near the Euripus who came to Delos. To him and to Epaminondas the son of Polymnis the Thebans erected statues here. CHAPTER XIII.
