Eraicon-RevelationsEraicon-Revelations book

On Nature was a book written by Empedocles, a hidden copy of which was found by Ezio Auditore da Firenze in the 16th century.


A major poetic work by the pre-Socratic Greek philosopher Empedocles, previously thought lost. Empedocles was one of the first to articulate a vague - if somewhat bizarre - version of the theory of evolution, which described a prehistoric world filled with autonomous body parts - free roaming eyes, hands, feet, organs etc. Over time, he argued, these parts gradually joined together in symbiotic union to create all the natural diversity we observe today.


  • While a copy of the poem is retrieved in-game by Ezio, in real life, the book remains lost, with only a quarter of it having survived in fragments.
