Pakal , The Mayan Astronaut

K'inich Janaab' Pakal (23 March 603 – 28 August 683) was ruler of the Maya polity of Palenque in the Late Classic period of pre-Columbian Mesoamerican chronology. During a long reign of some 68 years Pakal was responsible for the construction or extension of some of Palenque's most notable surviving inscriptions and monumental architecture.
Pakal’s tomb has been the focus of attention of some "ancient astronaut" enthusiasts since its appearance in Erich von Däniken's 1968 best seller, Chariots of the Gods?. Von Däniken reproduced a drawing of the sarcophagus lid (incorrectly labeling it as being from "Copan") and comparing Pacal's pose to that of 1960s Project Mercury astronauts, interpreting drawings underneath him as rockets, and offering it as evidence of a supposed extraterrestrial influence on the ancient Maya.
