Do you remember the stories about the native inhabitants of Puerto Rico that we were taught in school? Yes, the Taino Indians. They faded with the arrival of Spanish colonizers, according to the story. When exactly TaÌno ceased to exist?

Not only archaeologists and historians were interested in learning more about the Taino culture. A curious scientist that since he was a teenager was fascinated with stories about the Tainos, had in mind a number of questions, but mostly an effort to answer them.
