of the cathedral; largely because, now completed in its interior, and handy for all the ceremonies that were offered, there had not the urgent need to continue working on what was missing. Although the work had in fact been suspended, some works in the interior continued; by 1737 it was the master builder Domingo de Arrieta. He made, in the company of José Eduardo de Herrera, master of architecture, the stands that surround the choir. In 1742 Manuel de Álvarez, master of architecture, ruled with Herrera himself about the presbytery project presented by Jerónimo de Balbás. In 1752, on 17 September, a cross of iron, with more than three varas, with its vane, was placed on the crown of the lantern tower of this church, engraved on one side and on the other side the prayer of the Sanctus Deus, and in the middle of it a fourth-by-fourth oval, in which a wax of Agnus was placed on one side with its window and on the other side a sheet in which Saint Prisca, lawyer of the rays, was sculpted. The ear of the cross is of two varas, and all its weight is of fourteen arrobas; it is nailed to a quarry base. In 1787, the architect José Damián Ortiz de Castro was appointed, after a competition in which it imposed the projects of José Joaquín García de Torres and Isidro Vicente de Balbás, to direct the construction works of the bell towers, the main facade and the dome. For the construction of the towers, the Mexican architect Ortiz de Castro designed a project to make them effective against earthquakes; a second body that looks piercing and a bell-shaped finishing. His direction in the project continued until his death in 1793. When he was replaced by Manuel Tolsá, architect and sculptor driver of the Neoclassical, who arrived in the country in 1791. Tolsá is in charge of completing the work of the cathedral. He reconstructs the dome that was low and disproportionate, designs a project that consists of opening a larger ring on which builds a circular platform, to lift from there a much higher roof lantern. Integrates the torches, statues and balustrades. He crown the facade with figures symbolizing the three theological virtues (faith, hope and charity).
