The author shows that the very numerous extant portraits (engravings) of Paracelsus may be referred to four types. The portrait attached to the monument erected to Paracelsus in the church of St. Sebastian is of Paracelsus' Father ; this is established by oil paintings of both preserved in Salzburg.
