Hello everyone, i am a amateur math and science historian. I only basically know the major figures. But, i want to know more, and i was wondering if there are any historians who know a great deal, on this 'era'. For example like texts to read on the library of Alexandria, and the mathematicians who worked there. Pythagoras, any thing else related. These sorts of text. I have been searching for, but i wonder which you recommend, are the most reliable to get a full understanding.
