So powerful did he feel himself, that a fancy crossed his mind that, after all, he was no mere man, but the son of Jupiter, and a demi-god, like Bacchus, or Hercules of old.  There was a temple to the Egyptian god Ammon, on an oasis, a fertile spot round a spring in the middle of the desert, with an oracle that Alexander resolved to consult, and he made his way thither with a small chosen band.  The oasis was green with laurels and palms; and the emblem of the god, a gold disk, adorned with precious stones, and placed in a huge golden ship, was carried to meet him by eighty priests, with maidens dancing round them.  He was taken alone to the innermost shrine.  What he heard there he never told; but after this he wore rams’ horns on his helmet, because a ram’s head was one sign of the god, whom the Greeks made out to be the same as Jupiter; and from this time forward he became much more proud and puffed up, so that it is likely that he had been told by this oracle just what pleased him.
