Twenty years ago, a dilapidated temple painted from the inside with magnificent frescoes was discovered in the Mexican forests of Chiapas. It was the temple of the City of Painted Walls of the ancient mysterious Mayan people. Who is he, this amazing nation-builder? Where did he come from? How and when did his culture begin? Who taught him to write? What knowledge should he have if the Mayan calendar, created two millennia ago, turned out to be more accurate than our calendar? These and other questions are answered by V. A. Kuzmishchev's book "The Secret of the Mayan Priests."
