Check out the a full reproduction of the Hypnerotomachia Poliphili, one of the most famous early printed books. It was probably written by Francesco Colonna in the mid-15th century and beautifully printed by Aldus Manutius in 1499. There’s also a copy of the 1592 English translation (Poliphilo’s Strife of Love in a Dream), which attempts to preserve the typography of the original. And of course, Project Gutenberg has a plain text English translation.
