Peter De Abano 
Heptameron: or, Magical Elements 

A classic grimoire remade from several source manuscripts with quality in mind. Utilizing Robert Turner's fine enduring translation, much work was done to help facilitate the accuracy of the Latin sourcework. Access to Turners Early translation and Latin source manuscripts can be accessed via links in the frontmatter of this work. In his writings he expounds and advocates the medical and philosophical systems of Averroes, Avicenna, and other Arabian writers. His best known works are the Conciliator differentiarum quae inter philosophos et medicos versantur (Mantua, 1472; Venice, 1476), and De venenis eorumque remediis (1472), of which a French translation was published at Lyon in 1593. The former was an attempt to reconcile Arab medicine and Greek natural philosophy, by answering questions concerning anatomy and physiology. This style of though was called the Paduan School for Medical Dialectics. It was considered authoritative as late as the sixteenth century. It has been alleged that Abano also wrote a grimoire called the Heptameron, a concise book of ritual magical rites concerned with conjuring specific angels for the seven days of the week (hence the title). It should not be confused with the Heptameron of Marguerite of Navarre. He is also credited with writing De venenis eorumque remediis which expounded on Arabic theories concerning superstitions, poisons, and contagions.
