Quetzalcoatl (28-D) was the governor of the primitive Chichimecas, praised by the Toltecs of Tula as the founder god of their lineage. These people reached their major development between 900 and 1000, when they consolidated their culture in the ceremonial centre of Tula. But internal fights forced one part of the people to emigrate towards the west, lead by a personage who flaunted the name of the founder god.

On the Yucatan Peninsula a power centre of the Mayas was developed, but around the year 987, the people from the west arrived, a group of “Itzaes” warriors, lead by the new Quetzalcoatl, who the Mayas called Kukulkan. Both names have the same significance “snake decorated with feathers”. The newly arrived people dominated a small town, which had a natural well of sacered fame. This place is called Chichen Itza and the Toltec commanders begun to dominate the political life throughout the whole Yucatan Peninsula, included more remote places like those in Guatemala, where they arrived to form the town of Quiche. In the archaeological digs of the natural well of Chichen Itza, directed by Alfred P. Mausdlay in the 1940’s, there were rescued extraordinary jade pieces, among them the plates with details of governors and prisoners (28-A) and (28-B) and the plate representing a warrior (28-C) put above a snake, the body of which is decorated with studs of chalchihuites (jade stones).

On this natural well there were also found other jade pieces, which belonged to the dynasties of Mayan governors of the classic epoque of Piedras Negras and Palenque. How the got to chichen Itza three centuries later is not known.
