# Who is considered the greatest mathematician between the years 400 AD and 1300 AD? [closed]

Some mathematicians are considered the "greatest of their era". For instance, Archimedes is generally considered the greatest mathematician of Antiquity. Is there any mathematician who stood out similarly from the rest in that timeline?

• Considered by whom? I am sure different people (mathematicians, historians, etc) have different opinions. AFAIK, there is nobody in that time period who is comparable to say, Archimedes or, Diophantus, or Euclid, but this is just my opinion. May 9 '20 at 15:42
• For instance, somebody by the name James Allen (a programmer) lists here 100 greatest mathematicians of all times. Few people on his list (but pickings are slim), say, Muhammed al-Khowârizmi, fall into the time interval you are interested in. You can choose somebody else, say, Aryabhata.... May 9 '20 at 15:57
• The problem with lists like Allen's is that they mostly reflect the background knowledge/awareness of the list-maker, aside from a few notables that everyone includes. For example, among his top 100 are Einstein, Turing, Polya, Littlewood, Maxwell, Galilei (note that 3 of these are not even mathematicians). Absent in his top 100 (and born before 1930) are Erdős, Steinhaus, and Wiener who surely should be above Turing, Polya, and Littlewood! And why Turing and ignore Church and Kleene, both far more influential in mathematics than Turing, although none should probably be on a top 100 list. May 9 '20 at 19:49
• See mathshistory.st-andrews.ac.uk/Indexes/Full_Chron.html for a chronological list to choose from. E.g. Roger Bacon, Omar Khayyam, Guo Shoujing ... May 9 '20 at 22:38
• @Madhava: Regarding Erdős, Steinhaus, and Wiener, I think I'd put Erdős and Wiener on an all-time top 100 list, but almost certainly not Steinhaus (this would open up whether Kuratowski and Sierpinski should be on the list for me, and I suspect if I spent enough time going over names, I would have to exclude all three), so my comment should mostly be taken to mean who surely should be above Turing, Polya, and Littlewood (a no-brainer in my opinion, and I could probably come up with a dozen more who would be above these three and also who are not on Allen's top 100 list).
