Situa
The situa or citua (in Quechua situwa raymi) was the health and ritual purification festival in the Inca Empire. It was held in Cusco, the capital of the empire, during the month of September on the day of the first moon after the spring equinox, which in the southern hemisphere takes place normally on September 23. It was a very important festival whose rites are well described by the early Spanish chroniclers, in particular Cristóbal de Molina, Polo de Ondegardo and Inca Garcilaso de la Vega. The latter witnessed situas as a child after the Spaniards had reduced them to memorials of the actual Inca festival. The situa is also mentioned by Bernabé Cobo, who copied, most probably, its text from Molina,: xxii Felipe Guaman Poma de Ayala, Pedro Sarmiento de Gamboa and Juan de Betanzos.
