Jean de Roquetaillade [1] (date of birth unknown; d. probably at Avignon, 1366) was a French Franciscan alchemist.[2]

After studying philosophy for five years at Toulouse, he entered the Franciscan monastery at Aurillac, 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 prophecies and violent denunciation of ecclesiastical abuses brought him into disfavour with his superiors, resulting in his imprisonment in the local franciscan convents. During a transfer from one convent to another, he was able to reach Avignon and present an appeal before Pope Clement VI in 1349. While there he wrote in 1349 his Visiones seu revelationes, and in 1356 Vade Mecum in tribulatione[3] and Liber Ostensor. His other works include commentaries on the Oraculum Cyrilli, the recently discovered Sexdequiloquium and many other lost treatises and commentaries on various prophecies.
