Essays by Alain Touwaide, Jean Pierre Angremy,  Christian Förstel and Grégoire Aslanoff concerning the 10th century Byzantine illuminated manuscript designated as "BnF Supplement grec 247." This spectacularly illustrated manuscript is the only surviving Byzantine illuminated manuscript of these didactic poems.  The Theriaka  concern poisonous bites of snakes, scorpions insects and other animals from the sea, air or land. Nicander provided information in three main categories: physical description and ethology of the poisonous animals, the symptoms of their bites and stings, and finally treatment for poisoning. The Alexipharmaka  consists of 630 verses dealing with poisons absorbed orally from plants, animals and minerals, with a systematic tripartite division concerning the physical description of the solution in which the poison was mixed, clinical symptoms following the poisoning, and enumeration of specific therapies. Spanish text; superb color illustrations. This book was a commentary volume for a deluxe facsimile of the manuscript issued by Moleiro.
