Editing Number theory (section)

==== Western Europe in the Middle Ages ====
Other than a treatise on squares in arithmetic progression by [[Fibonacci]]—who traveled and studied in north Africa and [[Constantinople]]—no number theory to speak of was done in western Europe during the Middle Ages. Matters started to change in Europe in the late [[Renaissance]], thanks to a renewed study of the works of Greek antiquity. A catalyst was the textual emendation and translation into Latin of Diophantus' ''Arithmetica''.<ref>[[Bachet]], 1621, following a first attempt by [[Guilielmus Xylander|Xylander]], 1575</ref>
