Rodríguez Guerrero, José, "Desarrollo y madurez del concepto de quintaesencia alquímica en la Europa medieval (s. XII-XIV)", Azogue: Revista Electrónica Dedicada al Estudio Histórico Crítico de la Alquimia, 5 (2002 - 2007), 30-56.
- The quintessence was a key element in late medieval alchemy. I will discuss the origin of the concept from its vague beginnings in the 13th Century, well summarized by Restoro d'Arezzo (ca.1282), to the critical meeting in the early 14th century. I will focus my research on a less-known text by Ortholan of Paris, entitled Liber super textum hermetis (pre.1325). It consists of two sections. The first is a guide to elaborate a pure quintessence or “Stone of Life”, obtained by distillation and rectification of wine. Ortholan thought of alcohol as the quintessence almost a quarter of century before John of Rupescissa's book De quinta essentia. The second section of the Liber super textum hermetis is a popular commentary on the Emerald Tablet that usually circulated as an independent work. It defines quintessence as the first of all things created by God, the pure element of which the cosmos was made.
