Archaeologists work at the pre-Inca Moche site of San Jose de Moro in Peru
in an undated picture. Since 1991 archaeologist Luis Jaime Castillo Butters has led excavations at the site, which was a regional ceremonial center and cemetery for elite Moche people.
In September 2009 Castillo's team revealed their findings from a double-chambered tomb, the first of its kind found at the site. Their discoveries included ceramic bowls about 20 inches (38 centimeters) wide, which crowded the floor along the walls and filled overlying niches.
The large bowls were overflowing with smaller, thick-walled ceramic bottles, which may have been heated up and dropped into liquid-filled bowls to create a misty, ceremonial effect as bodies were lowered into the tomb, Castillo said.
