"Which god retained a higher level of cognizance in the Aztec psyche than most of their other gods, due primarily to its tenth-century departure from the Valley of Mexico and promised future victorious return?"

Quetzalcoatl

Explanation:

Quetzalcoatl is represented with a snake with feathers on his body. It contains a representation of the two natural conditions of all human beings: on the one hand, the earthly symbolized with the snake body and, on the other, the spiritual character of the bird represented with feathers. This God was characterized by his enormous wisdom.
