In another Aztec myth of creation, Quetzalcoatl and tezcatlipoca fashion the heavens and earth by dismembering the great
earth monster, Tlaltecuhtli. Although the name Tlaltecuhtli means Earth Lord , this being is actually dually
sexed and is often described as female. Tlaltecuhtli sometimes merges with another earth monster, a great caiman whose spiny
crocodilian back forms the mountain ridges of the world. The Tlaltecuhtli myth was widespread in Meso-america.
In one Aztec version ,Quetzalcoatl and Tezcatlipoca descend from the sky to observe Tlaltecuhtli striding upon the sea. So fierce is
her desire for flesh that not only does she have a great toothy maw, but also gnashing mouths at her elbows, knees and joints. Quetzalcoatl
and Tezcatlipoca transform themselves into two great serpents. One snake seizes the left hand and right foot of Tlaltecuhtli and the other her
right hand and left foot, and between them thet tear the monster apart. The upper portion of her body then becomes the earth, while the other half
is thrown into the sky to create the heavens.
The violent slaying and dismemberment of Tlaltecuhtli angers the other gods. To console the mutilated earth, they decree that all plants needed
for human life will derive from her body. From her hair are fashioned trees, flowers and herbs, and from her skin come the grasses and small flowers.
Her eyes are the source of wells, springs and small caves; her mouth, great rivers and caverns; and her nose, mountain ridges and valleys. At times, the
earth goddess can still be heard screaming in the night for the blood and the hearts of people. Ultimately, only sacrifical flesh and blood can soothe and
quiet Tlaltecuhtli sufficiently to keep her producing the fruits needed for human life.
