Original in Spanish
Located an hour and a quarter by car from Panama City, the Polanco stone displays fifteen strange drawings carved on its surface, with geometric shapes and human features, which present several enigmas: Who carved the drawings? When did they do it? For what purpose? The locals cannot answer these questions, although they have woven pagan and religious superstitions around the stone.
In this piece, Roberto Pérez-Franco describes the place for us, presents photographs of all the drawings carved on the stone, and tries to clear up the mystery with a curious and simple archaeological hypothesis based on basic principles of astronomy and on the rainfall pattern of the region. The hypothesis set out on this page has been on the web since February 2000.
