Ixtlilton, “Little Black Face,” is the name of a deity or divine force, also known as Tlaltecuin or Tlaltetecuini, "Earth-Stamper,” who “belonged with the Macuiltonaleque, the young solar deities who presided over flowers, feasting, singing, dancing, gaming, and painting and who bore the names of the five tonalpohualli (260-day religious divinatory calendar) days assigned to the south, with numerical coefficients of five (the number signifying ‘excess’). Their most prominent member was Macuilxochitl, ‘Five Flower.’" [See: Fray Bernardino de Sahagún, Primeros Memoriales, ed. Thelma D. Sullivan, et al. (Norman: University of Oklahoma Press, 1997), 101.]
