Olmec tomb The ancient Olmec civilization is believed to have been centred around the southern Gulf Coast of Mexico area (today the states of Veracruz and Tabasco) - further south east than the heart of the Aztec empire. The Olmec culture developed in the centuries before 1200BC (BCE), and declined around 400BC.
Archaeologists say the tomb of Aztec Emperor Ahuizotl likely lies beneath this stone monolith, discovered in Mexico City in 2006. (An update in 2008 indicates it's still looking good to be the tomb of at least one Emperor, but there may even be three http://sci.tech-archive.net/Archive/sci.archaeology/2008-06/msg00178.html )
An archaeologist works on a stone monolith at the Templo Mayor (Great Temple) site in Mexico City. The skeleton of a richly decorated canine and several unbroken plaster seals add to clues that the site could be the only known tomb of an Aztec king, researchers said in June 2009.
The city of #Oaxaca is well-known for having one of the best Dia de Los Muertos festivals in Mexico, a holiday celebrated in many parts of Latin America. In Mexico the festival can be traced back thousands of years ago to indigenous cultures such as the Zapotec and Aztec. In Oaxaca the Day of the Dead Festival starts at the end of October when families prepare the tombs for the return of the spirits.
