First published in 1871, Ancient America delivers the earliest comprehensive English‑language survey of North America's prehistoric past. Baldwin synthesizes scattered accounts—from the fluted‑point hunters of the Paleo‑Indian era to the monumental earthworks of the Mississippi‑Valley "Mound Builders," and onward to the pyramidal cities of Mexico and Central America—into a single, lucid narrative. Rejecting then‑common Eurocentric myths, he argues that these civilizations were "wholly original, wholly American," products of indigenous innovation rather than Old‑World transplantations. Richly illustrated with plates and informed by Baldwin's correspondence with leading thinkers of his day, this seminal work frames American antiquities within a global archaeological context and remains a cornerstone for understanding the continent's ancient ingenuity.
