The 'Inti Raymi'rata (Quechua for "sun festival") is a religious ceremony of the Inca Empire in honor of the god Inti (Quechua for "sun"), the most venerated deity in Inca religion. It was the celebration of the winter solstice - the shortest day of the year in terms of the time between sunrise and sunset and the Inca New Year. In territories south of the equator the gregorian months of June and July are winter months. It is held on June 24.
During the Inca Empire, the Inti Raymi was the most important of four ceremonies celebrated in Cusco, as related by Inca Garcilaso de la Vega. The celebration took place in the Haukaypata or the main plaza in the city.
The Inti Raymi was proceeded by a three day purification by the Sapa Inca and curacas. During that time, only water, uncooked corn, and chucam were eaten. At dawn on the June solstice, they gathered in the Haucaypata, took off their shoes, and faced northeast in anticipation of the rising sun. When the sun appeared, they would crouch down and blow respectful kisses, before raising two golden cups of chicha. The left cup was offered to the Sun, while the right cup was shared amongst the Sapa Inca and his retinue. From the plaza, they walked to the Coricancha, for the sacrifice of llamas, and in some cases, children.
According to chronicler Garcilaso de la Vega, Sapa Inca Pachacuti created the Inti Raymi to celebrate the new year in the Andes of the Southern Hemisphere. The ceremony was also said to indicate the mythical origin of the Incas. It lasted for nine days and was filled with colorful dances and processions, as well as animal sacrifices to thank Pachamama and to ensure a good harvest season.The first Inti Raymi was in 1412. The last Inti Raymi with the Inca Emperor's presence was carried out in 1535, after which the Spanish and the Catholic priests banned it.
In 1944, a historical reconstruction of the Inti Raymi was directed by Faustino Espinoza Navarro and indigenous actors. The first reconstruction was largely based on the chronicles of Garcilaso de la Vega and only referred to the religious ceremony. Since 1944, a theatrical representation of the Inti Raymi has been taking place at Saksaywaman, two kilometers from its original celebration in central Cusco on June 24 of each year, attracting thousands of tourists and local visitors.
Inti Raymi is still celebrated in indigenous cultures throughout the Andes. Celebrations involve music, colorful costumes (most notable the woven aya huma mask) and the sharing of food. In many parts of the Andes though, this celebration has been connected to the western festivals of Saint John the Baptist, which falls on the day after the northern solstice (June 21).
