John of Roquetaillade (de Rupescissa)
FREE Catholic Classes
Franciscan alchemist, date of birth unknown; d. probably at Avignon, 1362. After pursuing the study of philosophy for five years at Toulouse, he entered the Franciscan monastery at Orléans, where he continued his studies for five years longer. His experiments in distillation led to the discovery of what he termed aqua vitæ , or usually quinta essentia , and commended as a panacea for all disease. His work as an alchemist forms the subject-matter of "De consideratione quintæ essentiæ" (Basle, 1561) and "De extractione quintæ essentiæ"; likewise "Libellus de conficiendo vero lapide philosophico ad sublevandam inopiam papæ et cleri in tempore tribulationis" (Strasburg, 1659). His false prophecies and violent denunciation of ecclesiastical abuses brought him into disfavour with his superiours, resulting in his imprisonment by Clement VI (1345) and Innocent VI (1356). While there he wrote in 1349 his "Visiones seu revelationes", and in 1356 "Vade Mecum in tribulatione" and "Ostensor" (in Brown, "Fascicula rerum expetendarum et fugiendarum", III, London, 1640). His other works include commentaries on the Sentences and on the "Oraculum Cyrilli", "Fragmenta revelationum", "Apologus propheticus", "De famulatu philosphiæ ad theologiam".
