Who or what

Abu Zayd Hunayn ibn Ishaq al-Ibadi (809–873) was a Nestorian Christian scholar who became the most prolific translator of Greek medical and philosophical works into Arabic.

He was appointed director of the House of Wisdom's translation bureau under Caliph al-Mutawakkil and translated nearly all of Galen's works.

Why it mattered

Hunayn's translation method was rigorous: he compared multiple Greek manuscripts to produce the most accurate Arabic version.

He was paid by the weight of his translations in gold, reflecting the immense value placed on his work.

Key works and moments

He translated over 100 works of Galen, 17 of Aristotle, and numerous works of Hippocrates, Plato, and Dioscorides.

His "Book of the Ten Treatises on the Eye" was the first systematic textbook of ophthalmology.

Further detail

His method: first establish the best Greek text by comparing manuscripts, then translate into Syriac, and finally into elegant Arabic with a team of editors.

He developed Arabic medical terminology that became the standard across the Islamic world.

Legacy

Without Hunayn's translations, much of Galenic medicine and Greek philosophy would have been lost to posterity.

His translations later reached Europe via the School of Toledo, becoming the basis for medieval European medicine.
