the hospital in Gondeshapur, which supplied physicians to courts in Iraq, Syria, and Persia. He was called to Baghdad in 765 AD to treat the stomach complaint of the Caliph al-Mansur. After successfully curing the caliph, he was asked to remain in attendance in Baghdad, which he did until he fell ill in 769 CE. Before allowing him to return to Gondeshapur, the caliph invited him to convert to Islam but he declined, saying that he wanted to be with his fathers when he died. Amused by his obstinacy, the caliph sent an attendant with Jurjis to ensure he reached his destination. In exchange for the attendant and a 10,000 dinar wage, Jurjis promised to send his pupil Isa ibn Shahla to the caliph, since his son, Bukhtishu II, could not be spared from the hospital at Gondeshapur. Bukhtishu II Bukhtishu II was the son of Jurjis ibn Bukhtishu and the father of Jibril ibn Bukhtishu. He was left in charge of the hospital at Gondeshapur when his father was summoned to treat the stomach complaints of Caliph al-Mansur. Jurjis never intended for Bukhtishu II to go to Baghdad and tend to the caliphs and had offered to send one of his pupils in his stead.

In 791 AD, Bukhtishu II recommended Jibril as a physician to Jafar the Barmakid, the vizier of the Caliph Harun al-Rashid. Despite the recommendation, Jibril did not succeed his father until 805 AD, after he successfully treated one of Harun al-Rashid's slaves, thereby winning the confidence of the caliph. During Jibril's time in Baghdad, he advised Harun al-Rashid in the building of its first hospital. The hospital and connected observatory was modeled after the one in Gondeshapur where Jibril had studied medicine and served as the director. Jibril also served
