The Last Lords of Palenque: The Lacandon Mayas of the Mexican Rain Forest, by Victor Perera and Robert D. Bruce
I'm reading the book above on the Lacandon's right now. The main informant is the last elder of their tribe, the last traditionalist, in 1977, he was in his late 60's. He and a number of others, in his tribe of 170 people, one of the two tribes of Lacandons, (the other Christianized and numbering 250 people) the last decedents of the true Mayan civilization, these people regularly say, that when this old man dies, the developers will come, and they will have a road, and their way of life will be over. They will no longer be Lacandons, they will be westerners. No one in the next generation has the power to protect the people.
This was written over 30 years ago, when Chan K'in was an old man at 60. I can't help but feel... Something more then upset, and horror, and sadness together... at realizing I'm reading the last dispatch, the last history, the last contact with a civilization that died in the years it took me to find out they existed.
