ABSTRACT

Although the name and works of Jamshid Koshi, one of the great scholars of the Timurid dynasty, are known to many, many aspects of his life and work remain secret. The full name of the scientist is Ghiyasiddin Jamshid ibn Mas’ud ibn Mahmud Tabib al-Koshi (al-Koshani), born in the city of Koshan in northern Iran. The exact year of his birth is not known. It is believed to be before 1360. Because it is known that Qazizada Rumi (about 1360-1430)[1], who was born around this year, respectfully mentioned his name as “Mawlana”. Ghiyasiddin is his nickname. Grandfather Mahmud was a doctor and knew many sciences. Jamshid Koshi received his initial knowledge in his hometown of Koshan.
