In Mexico City's Plaza Tolsá, in front of the National Museum of Art, people gather on weekends to honor and preserve their Aztec heritage with music and dance. When I left the museum on Sunday, I found that during the short time that I had been inside, a large and elaborate "ofrenda" had been built on the plaza. But this "ofrenda" had no crosses or saints... it looked as if it might have been taken straight from the pre-conquest era of the Aztecs.

The skeletal image of a dog is a reminder that "xolos", the Mexican hairless dogs, were often buried with the dead to serve as guides through the underworld.
I can imagine that if the 16th century Catholic monks could see this, they would have been shocked that after five centuries the Aztec rituals have survived.
