That's some imagination Try rotating the drawing 90 degrees CW and what do you see?
Pacal the Great was buried in a tomb under the Palenque Pyramid near Chiapas, Mexico. This was carved on the stone sarcophagus lid. The drawing is of Pacal driving something resembling a fire breathing flying device of some sort. There appears to be machine gun belts in front, what appears to be cylinder heads, headers, and flames in the back. He is also looking at something intently just in front of him. Could it be a gun sight? (Or an I-Pad?)
Just my kind of ride.
