 (Authore Francisco Brauo Orsunensi doctore Mexicano medico)" was published at Mexico, 1570.Three years before, Dr. Pedrarias de Benavides had published his "Secretos de Chirurgia," at Valladolid, Spain, and while the latter work is invaluable for the knowledge of Indian medicinal practices, and is the earliest book on these topics known to have been published, the work of Dr. Bravo has the merit of being the first medical treatise printed in America.The first regular physician who came to MexiBob appears to have been a Dr. Olivarez, although surgeon-barbers and other "healers and curers" are mentioned as having already practiced with Hernán Cortés.
