Note 7 — STEPHEN THE MURDERER. Kriza, xviii.
Reading edition
A John Twardowski is said to have been a doctor of medicine in the university of Cracow, who, like Dr. Faust, signed a contract in his own blood with the devil. He is said to have been wont to perform his incantations on the mountains of Krzemionki, or on the tumulus of Krakus, the mythic founder of Cracow. The demon was to do all the magician bade him and to have no power over him until he met him at Rome, where he took good care not to go. Whether this gentleman is supposed to have ultimately become the lame fiend I know not. See Slavonic Folk-Lore, by Rev. W. S. Lach-Szyrma, in Folk-Lore Record, vol. iv. p. 62.
