What Abraham Lincoln studied

Abraham Lincoln, it is widely known, carried around two books: the Bible and Shakespeare. Did you know that, according to this blog, he carried a third? That's right, Euclid's Elements. More evidence of the decline of the western mind and its devaluing of both knowledge and the human faculties of perception is found in its neglect.

I thought Lincoln also carried around Aesop's Fables. Maybe he grew up studying Aesop but didn't carry the book with him. He obviously read Aesop at some point since he quoted him.
