Goddess I is the Schellhas-Zimmermann-Taube letter designation for one of the most important Maya deities: a youthful woman to whom considerable parts of the post-Classic codices are dedicated, and who equally figures in Classic Period scenes. Based on her representation in codical almanacs, she is considered to represent vital functions of the fertile woman, and to preside over eroticism, human procreation, and marriage. Her aged form is associated with weaving. Goddess I could, perhaps, be seen as a terrestrial counterpart to the Maya moon goddess. In important respects, she corresponds to Xochiquetzal among the Aztecs, a deity with no apparent connection to the moon.
