Laymann, Paul a German Jesuit, was born at Innsbruck in 1576, and died of the plague at Constance November 13, 1635. He was distinguished in life for a remarkable knowledge of canonical law, so that he became an oracle in these matters. His Moraltheologie, published first at Munich (1625, 4to), passed through many editions (one of the best at Mayence, 1723). His work, Justa defensio Sanctissimi Romani Pontificis, etc., in causa Monasteriorum et bonorum ecclesiastic. vacantium, etc. (Diling. 1631), was replied to by the Benedictine Roman Hay, in Aster inextinctus, and led to an answer by Laymann, entitled Censura Astrolog. ecclesiasticae, et Astri inextincti. After his death appeared his Jus canonicum (Diling. 1643) and Repertoriumn (Diling. 1644). See Wetzer u. Welte, Kirchen-Lex. 6:383.
