Shams al-Din al-Samarqandi ( Persian شمسالدین سمرقندی Schams od-Din Samarqandi ) was a mathematician, theologian, philosopher, logician and astronomer from Samarkand (Samarquand) ofthe 13th and 14th centuries.
Little is known of him. He wrote his major works around 1276. These included works on theology, philosophy (with a treatise on dialogues in philosophy), logic, mathematics, and astronomy. He was not one of the astronomers around Nasir al-Din al-Tusi at the Maragha observatory .
As a mathematician he wrote a twenty-page treatise ( Kitab Aschkal al-ta'sis , Book of Basic Theorems) on 35 propositions from Euclid's elements , where he wrote mathematicians such as Ibn al-Haitham , Omar Chajjam , al-Jawhari , Nasir al-Din al- Tusi and Athīr al-Dīn al-Abharī quoted. The treatise was commented on by Qadi Zada , among others . As an astronomer, he wrote an overview of astronomy and a star catalog (for the year 1276/77).
An attempt to prove the parallel postulate of Euclid comes from him , but sometimes he was also attributed to Athīr al-Dīn al-Abharī.
