In De instauranda Aethiopum salute (1627)--the earliest known book-length study of African slavery in the colonial Americas--Jesuit priest Alonso de Sandoval described dozens of African ethnicities, their languages, and their beliefs, and provided an exposA (c) of the abuse of slaves in the Americas. This collection of previously untranslated selections from Sandoval's book is an invaluable resource for understanding the history of the African diaspora, slavery in colonial Latin America, and the role of Christianity in the formation of the Spanish Empire; it also provides insights into early modern European concepts of race. A general Introduction and headnotes to each selection provide cultural, historical, and religious context; copious footnotes identify terms and references that may be unfamiliar to modern readers. A map and an index are also provided.
