For many years the prevailing debate about the Maya centred upon why their civilisation collapsed. Now, many scholars are asking: how did the Maya survive?

As a seven-year-old, Francisco Estrada-Belli was afraid all of history would have been discovered by the time he was old enough to contribute. The year was 1970 and he and his parents had come from Rome to visit relatives in the Central American country of Guatemala. On the trip, they visited the ancient Maya ruins at Tikal. “I was completely mesmerised,” Estrada-Belli told me recently. “It was jungle everywhere, there were animals, and then these enormous, majestic temples. I asked questions but felt the answers were not good enough. I decided there and then that I wanted to be answering them.”

Fifty-five years later, Estrada-Belli is now one of the archaeologists helping to rewrite the history of the Maya peoples who built Tikal. Thanks to technological advances, we are entering a new age of discovery in the field of ancient history. Improved DNA analysis, advances in plant and climate science, soil and isotope chemistry, linguistics and other techniques such as a laser mapping technology called Lidar, are overturning long-held beliefs. Nowhere is this more true than when it comes to Maya archaeology.
