The Casa del Deán houses frescoes of unique and incalculable artistic value, as well as centuries of history of a family that lived within its walls for generations. The part that is still preserved today is a museum administered by the INAH. There are 2 rooms left intact in the Dean's house of what was once the Spanish domination of the entity. The first preserved room: 1. It is La Sibilina, so called because of its walls decorated with representations of the women who received from the god Apollo the gift of prophecy and divination, known as Sibyls. Here we observe with delight a cavalcade full of color and plastic beauty; the Sibyls ride splendid steeds and wear luxurious dresses in the style of the sixteenth century: Eritrea, Samia, Persia, Europe, Cumea, Tiburtina, Cumana, Delphic, Helespontica, Italica and Egiptia parade before our eyes, who according to a pious tradition prophesied about the coming and the passion of Jesus Christ. It is worth remembering that these women were painted by Michelangelo in the Sistine Chapel. The cavalcade is set against a backdrop of presumably European landscapes. The Sibyls are accompanied by a multitude of tiny characters, as well as a wide variety of animals: rabbits, monkeys, deer, tigers and birds. Elaborate borders depicting fruits, plants, women' centaurs, children with wings, exotic birds and vases with flowers were painted on the upper and lower parts of the scenes described. 2. The room of the triumphs, in this space was the bedroom of the dean Don Tomás de la Plaza, and when contemplating in its walls representations of The Triumphs, work in verse of Petrarca, we realize the refined culture that the priest possessed. The Triumphs were written in hendecasyllabic tercets and are an allegory not only of Petrarch's love for Laura, but also of the human condition. Broadly speaking, the poem shows the triumph of Love over men, but it is defeated by Death, over whom Fame triumphs, defeated in turn by Time, which yields to Divinity. On the four walls of the room these ideas of the poem are recreated plastically as a fact more for reflection than for simple amusement. As in the room of La Sibilina, in the room of Los Triunfos we find all the scenes framed with elegant friezes filled with animals, vegetal motifs, women's faces, infantile fauns and children with wings. In both rooms the murals were painted with the tempera technique by anonymous skilled artists.
