Life and
works
Nothing
is known of al-Samarqandi's life except that he composed his most important
works in the last two decades of the 7th and early decades of the 8th centuries
A.H. He wrote works on theology, logic, philosophy, mathematics and astronomy
which have proved important in their own right and also in giving information
about the works of other scientists of his period. Al-Samarqandi wrote a work
Risala fi adab al-bahth which discussed the method of intellectual
investigation of reasoning using dialectic. Such methods of enquiry were much
used by the ancient Greeks. He also wrote Synopsis of Astronomy, and produced a
star catalogue for the year 1276-77. In mathematics, al-Samarqandi is famous
for a short work of only 20 pages which discusses 35 of Euclid's propositions.
Although a short work, al-Samarqandi consulted widely the works of other Muslim
mathematicians before writing it. For example he refers to writings by Ibn
al-Haytham, Omar Khayyam, al-Jawhari, Nasir al-Din al-Tusi, and Athīr al-Dīn
al-Abharī.
