In May 2008 a team of researchers forming part of the Templo Mayor project of the historic centre of Mexico City, discovered a large offering which had been placed underneath an enormous statue of the goddess Tlaltecuhtli.
Underneath Mexico City lie the ruins of Tenochtitlan, the Aztec capital, and at its centre was the Templo Mayor. The project researchers believe that this offering was made during the reign of Ahuizotl, who was ruler of the Aztec empire for sixteen years, from 1486 to 1502, and in that time conquered 45 Mesoamerican territories.
Offering 126, the largest found so far at the Templo Mayor, is composed of almost 4,000 organic remains, of which three-fourths (3,045) are marine molluscs. Read more.
