Ancient Ocean Crossings

Reconsidering the Case for Contacts with the Pre-Columbian Americas
Paints a compelling picture of impressive pre-Columbian cultures and Old World civilizations that, contrary to many prevailing notions, were not isolated from one another, evolving independently, each in its own hemisphere. Instead, they constituted a ""global ecumene,"" involving a complex pattern of intermittent but numerous and profoundly consequential contacts.

In Ancient Ocean Crossings: Reconsidering the Case for Contacts with the Pre-Columbian Americas, Stephen Jett encourages readers to reevaluate the common belief that there was no significant contact between the emerging civilizations of Eurasia and Africa and peoples who occupied the terra incognita beyond the great oceans.

More than a hundred centuries separate the time that Ice Age hunters are conventionally thought to have crossed a land bridge from Asia into North America and the arrival of Columbus in the Bahamas in 1492. Traditional belief has long held that earth’s two hemispheres were essentially cut off from one another as a result of the post-Pleistocene meltwater-fed rising oceans. These oceans, along with deserts and mountains, formed impermeable barriers to interhemispheric communication. This viewpoint implies that the cultures of the Old World and those of the Americas developed independently.

Drawing on abundant evidence to support his theory for significant pre-Columbian contacts, Jett suggests that many ancient peoples had both the seafaring capabilities and the motives to cross the oceans and, in fact, did so repeatedly and with great impact. His deep and broad work synthesizes information and ideas from archaeology, geography, linguistics, climatology, oceanography, ethnobotany, genetics, medicine, and the history of navigation and seafaring, making an innovative and persuasive multidisciplinary case for a new understanding of human societies and their diffuse but interconnected development.
