This week Neil MacGregor is exploring the growing importance of agriculture around the world at the end of the Ice Age, with objects that show and celebrate the key elements of the time; power, sex, worship and food. Today the series focuses on the world of the Mayan civilisation and a stone Maize God, discovered on the site of a major Mayan city in present-day Honduras. This large statue is wearing a headdress in the shape of a giant corn cob.

Maize was not only worshipped at that time but the Maya also believed that all their ancestors were descended from maize. Neil MacGregor reveals why maize, which is notoriously difficult to refine for human consumption, becomes so important to the emerging agriculture of the region.

Neil is joined by the anthropologist Professor John Staller and the restaurateur Santiago Calva who explain the complexity of Mayan mythological belief and the ongoing power of maize in Central America today Show less
