It has been necessary to show the Hospital de Tavera as a model, for the building hides the Visagra Gate, and the dome obscures part of the town, and once treated as a model and moved from its place, it seemed better to me to show the main façade.... the rest, and its proper relationship to the town can be seen on the plan. Also, in the representation of Our Lady presenting the Chasuble to Saint Ildefonso, in making the figures large, I have applied, in some way, the observation made of celestial bodies that an illuminated body seen at a distance may appear large although it be small.
