Nezahualcoyotl was ruler of the city-state of Texcoco in pre-Columbian Mexico. Unlike other high-profile Mexican figures from the century preceding the Spanish Conquest, Nezahualcoyotl was not a 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.
Nezahualcoyotl has been remembered as a poet. This is because a number of poems in the Classical Nahuatl language written in the 16th and 17th centuries have been ascribed to him. One of his poems is almost hidden on the Mexican 100 Peso Note
Amo el canto de zenzontle
Pájaro de cuatrocientas voces,
Amo el color del jade
Y el enervante perfume de las flores,
Pero más amo a mi hermano: el hombre.
I love the song of the mockingbird,
Bird of four hundred voices,
I love the color of the jadestone
And the enervating perfume of flowers,
But more than all I love my brother: man.
