Georgios (Jorjis) bin Bakhtyeshun, of Jondshapur, lived at the commencement of the Abbaside dynasty, and was the author of the book of Pandects. When Al-Mansur was building the city of Baghdad he suffered from pains in his stomach and from impotency, and Georgios, the director of the medical college at Jondshapur, was recommended to him as the most skilled physician of the time. Accordingly, the Khalif directed Georgios and two of his pupils, Ibrahim and Serjis, to come to Baghdad, appointing Gabriel (Jebrayl), the son of Georgios, as director of the hospital in the place of his father. Georgios cured Al-Mansur, and received from him three thousand ducats for his reward, along with a beautiful slave girl; the latter was, however, returned to the Khalif with thanks, and the remark that, 'being a Christian, he could not keep more than one wife.' From that moment the physician attained free access to the harem, and enjoyed high favour with the Khalif, who greatly pressed him in A.D. 770 to make a profession of Islam; but this he refused to do, and died shortly afterwards, in A.D. 771. Before his death Georgios asked to be allowed to return to Jondshapur, to be buried there with his ancestors. Al-Mansur said, 'Fear God, and I guarantee you paradise.' Georgios replied, 'I am satisfied to be with my ancestors, be it in paradise or be it in hell.' The Khalif laughed, allowed him to return home, and presented him with ten thousand pieces of gold for his travelling, expenses. Gabriel (Jebrayl), the son of the above-named Georgios (Jorjis), was also a celebrated physician. He enjoyed great favour with Harun-ar-Rashid, who used to declare that he would not refuse him anything. When, however, this Khalif fell ill at Tus, and asked Gabriel for his opinion, the latter replied that if Harun had followed his advice to be moderate in sexual pleasure, he would not have been attacked by the disease. For this reply he was thrown into prison, and his life was saved only by the chamberlain Rabi'i, who was very fond of him. Amin, the son and successor of Rashid, followed the advice of Gabriel more than his father did, and would not eat or drink anything without his doctor's sanction. In A.D. 817 Gabriel cured Sehl bin Hasan, who recommended him to Mamun; but Michael, the son-in-law of Gabriel, was his body physician. In A.D. 825 Mamun fell sick, and, as all the medicines of Michael were of no use, Isa, the brother of Mamun, advised him to get himself treated by Gabriel, who had known him from boyhood; but Abu Ishak, the other brother of Mamun, called in Yahya bin Maseweih, and when he could do nothing, then Mamun sent for Gabriel, who restored him to health in three days, and was handsomely rewarded in consequence. When Mamun marched, in A.D. 828, against the Byzantines, Gabriel fell sick and died, whereon the Khalif took Gabriel's son with him on the campaign, he being also an intelligent and skilled physician.
