Quechuan-speaking Indians sit behind huge piles of potatoes, carrots, herbs, and other vegetables in one corner of the square. They sell these products to buy essentials (salt, sugar, kerosene, matches, medicines) but also trade to acquire other foods, such as oranges from the Quillabamba Valley. It exists side-by-side to the Pisac market but ends by 3 p.m. so that villagers can walk home before dark. Also on Sundays only, masses in Quechua are held at 6 and 11 a.m. in San Pedro Apóstol de Pisac, the colonial church on the main square that was rebuilt after the 1950 earthquake. The early mass is held for townspeople, and the later one is reserved for the varayocs and regidores (elected mayors and their appointed deputies) of the 13 villages that are a two- to five-hour walk away through the mountains. After mass, the officials proceed around the square in their Sunday best before a series of baptisms, and sometimes a wedding, are held in the church. Between services, it is possible to enter the church for a glimpse at the Inca foundations and an interesting collection of colonial paintings.
