Xochiquetzal, from the Codex Borbonicus. In Aztec mythology, Xochiquetzal was a goddess associated with concepts of fertility, beauty, and female sexual power, serving as a protector of young mothers and a patroness of pregnancy, childbirth, and the crafts practiced by women such as weaving and embroidery. Xochiquetzal is also representative of human desire, pleasure, and excess, appearing also as patroness of prostitutes and artisans involved in the manufacture of luxury items. The Codex Borbonicus is an Aztec codex written by Aztec priests shortly before or after the Spanish conquest of Mexico. Like all pre-Columbian codices, it was originally entirely pictorial in nature, although some Spanish descriptions were later added. There is dispute as to whether the Codex Borbonicus is pre-Columbian, as the calendar pictures all contain room above them for Spanish descriptions.
