Types of Mankind: Or, Ethnological Researches, Based Upon the Ancient Monuments, Paintings, Sculptures, and Crania of Races, and Upon their Natural Geographical, Philological, and Biblical History

"Types of Mankind" is a seminal work by Josiah Nott and George Gliddon, published in 1854. It explores human diversity through an ethnological lens, examining ancient monuments, art, and crania to categorize races. The authors argue for the distinctiveness of various races based on geographical, linguistic, and biblical contexts. Their research reflects 19th-century views on race and human development, often supporting then-prevalent theories of racial hierarchy. While influential, the work is criticized today for its pseudoscientific approach and flawed methodology, highlighting the evolution of anthropological perspectives on race and human variation over time.
