TITLE: Original works of great mathematician Évariste Galois
QUESTION [36 upvotes]: Through this question I wanted to know the original works of Galois. When I was reading Galois theory ( since from last month ) , I have been seeing one common line in every book, whose essence appears as follows :
" The original work of Galois is rather different from the presented version here ( which is due to Artin ) , the original works of Galois are different since the concepts like automorphisms and other things were not discovered at the time of Galois. "

I am curious to know what are the notions that Galois used  ? , and what is the corresponding formulation of Galois theory, ( corresponding to the present version now which uses the modern vocabulary of Automorphisms ) .

But on the other hand , is there any complete biographical sketch of  Évariste Galois ? . But I really wanted to know about him, I think there is not a single original picture of him. But there was an original photograph of Master Gauss with me ( but I don't have a original picture of Galois, rather than the portrait drawn by his friend and I would be much happy if someone gives a link to any rare picture other than the normal ones ).
Thanks everyone.

REPLY [3 votes]: You might be interested in Peter Neumann's book The Mathematical Writings of Évariste Galois, which has English translations of Galois' work. The book is notable for its completeness and attention to detail. Neumann translated every piece of writing we have from Galois, including scraps of paper and incomplete writings. His translations include phrases that Galois crossed out, and even keep track of the number of lines Galois used when he crossed out a phrase!
