Feast in the hacienda "La Angostura"

This impressive group portrait shows the participants of an unspecified party at the hacienda 'La Angostura' in 1929, in Cusco. In the two-storey courtyard with a wooden balcony, gathered the people connected in various ways to the farm. In the courtyard stand the peasants employed by the hacienda, dressed in ponchos or common clothes and hats (one notices all types: from the woolen chullo to the montera, to the more western wide-brimmed hats called sombrero), but also a group of military personnel in uniform (bottom left).
From the top of the gallery, on the other hand, poses the bourgeois family who own the land, together with some soldiers, perhaps members of the family, and a friar (all on the left). A few men and women in bourgeois clothing pose instead in the back row in the courtyard, on a sort of elevation, together with some campesinos at their sides.
The whole building is decorated with festoons and plants. In the first row, a man holds what clearly looks like a Catholic liturgical banner, and at his sides some other campesinos sport masks and disguises.
The three men on the right have stiff masks and wear monteras, capes, elaborate jackets and chuspas (bags) and/or warakas (slingshots) crossed over their chests. The first adult from the left appears to wear a fabric mask with painted details, a kind of wig made of animal hair and a robe with abundant black fringes, and holds a kind of whip in his hand. At his side, a native in a poncho holds an imposing staff decorated with horizontal metal bands: it's a vara, the commanding stick of the indigenous authorities.
The costumes are reminiscent of the Qhapaq Qolla (men on the right) and Ukuku (men on the left) types respectively, typical of the pilgrimage to Quyllurit'i (a sincretic festivity very popular in the area) but also of the Cusqueña procession for Corpus Christi/Domini, a festivity very much felt in the region that combines the Catholic celebration of Pentecost with elements of pre-Hispanic cults. If the feast in hacienda was linked to Corpus Christi, this could explain both customs and the liturgical banner.
