What is "nezahualcoyotl"

Nezahualcoyotl (, , meaning "Coyote in fast" or "Coyote who Fasts") (April 28, 1402 – June 4, 1472) was a philosopher, warrior, architect, poet and ruler ( tlatoani) of the city-state of Texcoco in pre-Columbian era Mexico. Unlike other high-profile Mexican figures from the century preceding Spanish conquest of the Aztec Empire, Nezahualcoyotl was not Mexica; his people were the Acolhua, another Nahuan people settled in the eastern part of the Valley of Mexico, settling on the eastern side of Lake Texcoco.

He is best remembered for his poetry, but according to accounts by his descendants and biographers, Fernando de Alva Cortés Ixtlilxóchitl and Juan Bautista Pomar, he had an experience of an "Unknown, Unknowable Lord of Everywhere" to whom he built an entirely empty temple in which no blood sacrifices of any kind were allowed — not even those of animals. However, he allowed human sacrifices to continue in his other temples.
