Sinan ibn Thabit
Abu Said Sinan ibn Thabit ibn Qurra (* around 880 ; † 943 in Baghdad ) was a doctor , astronomer and mathematician .
He was the son of the mathematician and astronomer Thabit ibn Qurra , who worked at the court of the caliph in Baghdad. His son Ibrahim ibn Sinan was also an eminent mathematician.
His father died in 901. Sinan made a career under the caliph al-Muqtadir , who ruled from 908, and became head of the hospitals in Baghdad. Around 931, all doctors who practiced in Baghdad had to be examined beforehand by him. At that time, like his father, he was still a follower of the Sabian sect of Harran . When the Caliph al-Qahir came to power in 932 , the Sabians were persecuted. Sinan switched to Islam but lost his post anyway and fled to Khorasan . Under the reigning caliph ar-Rādī bi-'llāh from 934 , Sinan returned to Baghdad, but after his death in 940 he left Baghdad again in the government turmoil and went to Wasit on the Tigris.
Sinan no books or treatises on medicine known, but he wrote about politics (where he is a government modeled on the Republic of Plato advocated), mathematics and astronomy and dealt with philosophy. However, no works can be ascribed to him with certainty. One of his astronomical works is connected with the Sabier religion, the assignment of planets to individual days. In another work, obtained in excerpts from al-Biruni , it deals with the meteorological quality of anniversaries.
