Built in the shape of a Latin cross, the basilica develops longitudinally, starting from the three aisles that divide the central body with nine rows of columns. Closing your eyes, following the outline of the columns, rhythmically arranged on each side of the central aisle, and touching the cold marble, is a way to mystically connect with the antiquity. The eighteen columns support capitals, irregularly distributed according to the size of the shaft, which in turn are topped by pulvinos that establish the beginning of the mosaic ornamentation of the walls, in an increasingly intense decorative rhythm.
