Zelia Nuttall is an American archeologist born in San Francisco (September 6, 1857) and educated abroad. She worked with the Peabody Museum at Harvard and among her publications is this volume she edited, and, published in 1903:
The book of the life of the ancient Mexicans, containing an account of their rites and superstitions: an anonymous Hispano-Mexican manuscript preserved at the Biblioteca nazionale centrale, Florence, Italy..
The work is about the pre-Aztec culture, and contains a rendering of a jaguar, to my knowledge significant in all South American cultures. The jaguar in this volume though is definitely a vrey realistic skinned animal.
