Al-Fadl ibn Naubakht

Al-Fadl ibn Naubakht, (also written Nowbakht), was an 8th-century Persian scholar at the court of the Caliph Harun al-Rashid. He was son of the famous Naubakht, a former Zoroastrian, who had designed Baghdad.

Fadl was appointed by the Caliph as chief librarian of the Khizānat al-Hikmah (The Treasury of Knowledge), which later came to be known as The House of Wisdom. He also wrote astrological treatises, and his skills in translation were used to access Greek texts extensively.
