Today, we often see the Amazon basin as an endless expanse of trees and rainforest. But 2,000 years ago, at the same time that great cities like Rome, Athens and Alexandria were at their height, this massive area of South America was home to a huge range of landscapes, biodiversity and ancient Amazonian civilisations.

In this episode of The Ancients, Tristan Hughes is joined by author and journalist Laurence Blair - whose new book Patria: Lost Countries of South America is out today - to explore the extraordinary cultures that lived all across the ancient Amazon basin and unpack stories of agriculture, farming and fish-fuelled cities that go back 8,000 years.

Presented by Tristan Hughes. The audio editor is Aidan Lonergan, it was produced by Joseph Knight. The senior producer is Anne-Marie Luff.
