by Matthew Platearius, d. 1161

The Circa instans, attributed to Matthaeus Platearius (died 1161), was one of the most influential botano-medical texts of the high Middle Ages and beyond, featuring in around 240 mss. and several languages. This website presents a modern English translation of the text by Anna Kirkwood Graham, Brandon Conley, and Madi Pehringer. We are basing our translations on two easily accessible editions, one digital:

Translated from the Arabic by Gerardus de Sabloneto and Simon a. Cordo.
