Chancel arch & high altar

"The high altarpiece, slender and soaring, is one of the pièces de résistance of Mexican art, designed like a folding screen. Circa 1567-68 the painter Andrés de Concha was brought from Seville {...} to do the original altarpiece. The present work, of the 17C, incorporating Concha's 16 original paintings, was modified in 1718-20. It is in four storeys and seven vertical sections divided by solomonic columns; the centre section broad and ending in an elaborate top-piece, the two centre lateral sections, placed obliquely to it as the screen folds, ending in smaller statues of saints, probably originals, the word of a local sculptor using estofado, but later overpainted. In the lowest storey are four apostles; in the upper three are four preachers, four doctors of the Church, and four founders of Orders." (Collis, p. 686)
