Necromancy is given as a proof of the immortality of the soul in Justin’s First Apology, cap. 18, where we read, “For let even necromancy, and the divinations you practise by means of immaculate children, and the evoking of departed human souls ... let these persuade you that even after death souls are in a state of sensation.”
