Also worth asking, are you willing to learn 2000+ year old greek to read Euclid or for Euler learn Latin (the language in of scholarship in his time)? One reason that we have and use more modern math textbooks is changes in language and notation over time. Also it is often the case that the original proof is far from the best that has been found since there is now more structure developed in later works that allows either condensing or a novel approach. If you limit yourself to pre-1900 works, you throw out the vast majority of Graph Theory losing all contributions by Erdos, Kuratowski, Tutte, Ramsey, etc. Sorry, there are areas of math that need at least up to the 1950's to get major theorems.
