Al-Natili

Natili. Abu Abdallah Husayn ibn Ibrahim ibn Hasan ibn Khurshid at-Tabari an-Natili, was a Persian physician from Tabaristan.
He is most famous for being the tutor of the influential polymath Ibn Sina. Later, Ibn Sina was largely
dismissive of Natili's influence but acknowledged that his interest in medicine
arose in the course of his studies with him. As Ibn Sina was largely dismissive of most contemporaries, such as Al Biruni, Abu ‘l- Faraj, and more, this actually speaks to the level of respect Natili must have commanded.
He flourished in the 10th century, and was a translator of Greek into Arabic. He dedicated, in 990-991AD, an improved translation of Dioscorides' De Materia Medica to the Prince Abu Ali al-Samjuri. Ibn Sina later included large
sections of it in the fourth book of The Canon of Medicine, which was the authoritative source of medieval medicine for centuries.
