It is rarely appreciated how much of the history of Eurasian medicine in the premodern period hinges on cross-cultural interactions and knowledge transmissions. Using manuscripts found in key Eurasian nodes of the medieval world - Dunhuang, Kucha, the Cairo Genizah and Tabriz - the book analyses a number of case-studies of Eurasian medical encounters, giving a voice to places, languages, people and narratives which were once prominent but have gone silent.
