Muhammad ibn Ibrahim ibn Habib ibn Sulayman ibn Samra ibn Jundab ^[1] al-Fazari ( Arabic: محمد بن إبراهيم بن حبيب بن سليمان بن سمرة بن جندب الفزاري) (died 796 or 806) was an Arab philosopher, mathematician and astronomer. ^{[2] [3] [4]}

Biography

Al-Fazārī translated many scientific books into Arabic and Persian. He is credited to have built the first astrolabe in the Islamic world. ^[5] He died in 796 or 806, possibly in Baghdad. ^[6]

At the end of the 8th century, whilst at the court of the Abbasid Caliphate, al-Fazārī mentioned Ghana, "the land of gold." ^[7]

Works

Along with Yaʿqūb ibn Ṭāriq, al-Fazārī helped translate the 7th century Indian astronomical text by Brahmagupta, the Brāhmasphuṭasiddhānta, into Arabic as ' Zij as-SindhindAz-Zīj ‛alā Sinī al-‛Arab, ^[8] or the Sindhind. This translation was possibly the vehicle by means of which the mathematical methods of Indian astronomers were transmitted to Islam. ^[9]

The caliph^{[ which?]} ordered al-Fazārī to translate the Indian astronomical text, The Sindhind, along with Yaʿqūb ibn Ṭāriq, which was completed in Baghdad about 750, and entitled Az-Zīj ‛alā Sinī al-‛Arab. This translation was possibly the vehicle by means of which the Hindu numeral system (the modern number notation) was transmitted from India to Iran.

Al-Fazari composed various astronomical writings ("On the astrolabe", "On the armillary spheres", "on the calendar").
