done so, would have proved his ruin; but, fortunately, this vision of
his father made such an impression on him that he abandoned the idea
altogether.

Lucan[64] describes how Sextus Pompeius went to consult Erichtho, one of
the famous Thessalian witches, as to the prospects of his father's
success against Cæsar, during the campaign that ended in the disastrous
defeat at Pharsalia. It is decided that a dead man must be called back
