Ostotempan

There is a well in this town near Chilpancingo. I translate the following from:

La Fiesta de la Santa Cruz y los Pueblos Indígenas.

This celebration is at May 3 every year.

From the above link I took the following:

"In an article on rain ceremony in the Ostotempan mountain well to which Guerrero state nahuatl indigenous groups attend (Zumpango del Río, Mártir de Cuilapan, Ixtla de Guerrero, Mochitlán and Chilpancingo de los Bravo) María Teresa Sepúlveda states that the rain ceremonies and rituals occupy a good part of the time of agricultural peoples constituting the main part of the yearly ceremonial cycle.

Ostotempan is considered the center of the world, because God lives there keeping the water and wealth. Inhabitants believe that at the bottom of Ostotempan there are four caves where one can find seeds and all colors of corn guarded by four "giants" with "tlacololero" masks who produce thunder with their whips; each giant represent one of the four winds, the one in the East attracts clouds to produce good rain. "

I have another book: "La Historia del Estado de Guerrero a Través de su Cultura" The History of Guerreo through its culture, by Miguel Ángel Gutiérrez Ávila, edited by Universidad Autónoma de Guerrero. From this I translate the following:

";the one in the North brings hail, cold and bad rains; the one from the East blows away the clouds and produces drought and, the South one, sometimes brings good rain and others bad."

According to Prof. Stahl from Oklahoma University, we are getting the effects of the East giant.
