The column rests on a base where there is a figure with beard to his chest (perhaps an image of Noah) and two lions. At the foot of the central column at the top inside, looking towards the main altar of the cathedral, there is the kneeling figure of the Master Mateo himself, holding a sign on which is written Architectus. This image is popularly known as Santo dos Croques from the ancient tradition of students hitting their heads against the figure for wisdom, a tradition that was adopted later by pilgrims, although steps are being taken to limit access, to stem deterioration from which the work has suffered.
