Galen’s name appears in several contexts of Asian medical traditions, and while those references do not come with much substantial medical input, their existence and contexts are important to delineate. Galen comes to Asia through mediating languages, primarily Arabic, Persian, and Syriac. The conduits that caused this knowledge to traverse Asia were a combination of empire and religion: translation projects between Greek, Syriac, and Arabic during the Abbasid dynasty, the movement of Islam and Eastern Christianity through Asia, the Mongol Empire and its lingering effects, followed by transmissions facilitated by Western (Christian and Muslim) missionaries. These were underlying causes with which we can explain how, when, and where we find Galen in pre-modern Tibet and China.
