Tlanchana or Altanchane, queen mother goddess, sorceress of the lagoon, water mother spirit, protector and sustainer of Chignahuapan. Belonging to the traditional and local folklore of the folks of the nets, the Matlatzinca people, whose mythology around Atl-tonan Chane predates the Mexica power over the Nine Waters. Her appearance was that of gray or black skin, fish-woman, snake-woman, covered in flower necklaces, long hair, uncovered chest and a crown on her forehead. Mother guardian and protector of the Nine Waters.The goddess spent her days on an islet, in the waters behind the tule and herbs, in the marshy area for 11 thousand years, near Xinantécatl (Toluca snow) and the Chignahuapan river (Lerma river) along with the rest of Matlatzincas and Otomíes, who lived from the flora and fauna of the then lacustrine area full of lagoons and swamps. Usually naked, only with flower necklaces, a crown that reflected the light of the moon, dressed in jewelry, necklaces and strings of fish, perhaps frogs, snakes and axolotls at her waist. When she’s happy she boasts her black tail, this was a good omen for the fishing people, because it meant abundance. She’s a deity of an unstable, vengeful and possessive character as much as she’s protective and supportive. A persistent duality in Mesoamerican cosmology. The male locals would watch the beautiful woman, hidden behind the tule trees in the lagoon, as she swam through the waters of the islet and the moonlight reflected her crown and silhouette. She also is a divinator, being consulted before fishing, battle, sowing and marriage. Showing a practically vital role in the societies of people living in the Nine Waters. In the homes they had an idol of mud from Tlanchana so that food never lacked. She is the mistress and madame of the swamp, mother and creator of everything in the lagoon, from her came all the marine animals of the place. Fishes, axolote, cozens and frogs. Summoned to be venerated.The snake-woman, when in love, left the islet and transformed her tail into two legs to go and seduce a man with her melody, but when she was rejected, with her snake tail she surrounded him and dragged him to the water until drowning him or took him to the caves from the nearby hills and from there they descended to the underground rivers, those who disdained their love usually disappeared. Its tail was transformed into that of a fish when it wanted to swim through the waters of the lagoons and fill with food the nets of those who fished. In the 90s a statue in her honor was made and installed in the called parque Juárez, coming from a place of continuous and existing devotion and love from the locals.Metepec’s mud handcrafts of Tlanchana are iconic of the zone, after the recovery of her image with the almost disappearance of her legend the pottery culture and syncretism revived her story and knowledge, now with tail of fish, decorating it with flowers and marine animals, probably because of the influence of the old world. Sustainer and protector of Metepec. Those who know her power and charm put a serpient’s tail.
