In the National Museum of Guatemala lies the Altar Stone of th | World Theatre
In the National Museum of Guatemala lies the Altar Stone of the Great Incas, dating back to 653 AD. A metal pipe comes out of the limestone, and the cavity of the pipe is also filled with limestone.
The question is, how did Indians running around the prairies without pants make a trumpet in the 7th century? There were no pipe-rolling machines yet, I can tell you for sure.
