Libellus de Medicinalibus Indorum Herbis (Cruz-Badiano codex, 1552)

A herbal of Nahua medicine finished at the Colegio de Santa Cruz de Tlatelolco on 22 July 1552, dictated in Nahuatl by the indigenous physician Martin de la Cruz and put into Latin by the indigenous Latinist Juan Badiano. It is the earliest book of medicinal plants of the native peoples of the Americas, painted by Nahua scribes, and it was made to raise money to keep the college that produced it open.
