Mexican Aztec/Christian Holiday ("Dia de Los Muertos") Decoration: "Calavera Catrina"

This Mexican "Calavera Catrina" figure is a skeleton used to celebrate the Aztec/Christian holiday of "Dia de los Muertos", or Day of the Dead. The figure is a modern addition to this ancient holiday, starting out as an etching in the 1910s.

Dia de los Muertos started thousands of years ago with the Aztec, Toltec, and other peoples of Mesoamerica. For these ancient cultures, mourning the dead was believed to be disrespectful because death was a natural part of the life cycle. The memory and spirits of the dead were kept alive through various memorial days, religious rituals, and celebrations. Skulls were used to honor the dead. During celebrations, people wore costumes and used "caretas", or masks, to scare the dead away at the end of the festivities.

After the Spanish conquest, these indigenous religious traditions were absorbed into Catholic celebrations. Today, Day of the Dead festivities happen over two days to demonstrate love and respect for deceased friends and family members.
