I'm starting to read Sir Thomas L. Heath's translation of Diophantus:
Diophantus Of Alexandria: A Study In The History Of Greek Algebra
My motivation is to understand more of Fermat's thinking. Also in this volume are "some of the more remarkable solutions of difficult Diophantine problems" by Euler.
Just wondering other people's experience in reading Diophantus, the level of difficulty and what it taught them or how it relates to other mathematics.
