Clergymen of both sexes, gathered in front of Santa Maria del Fiore church, in different attitudes: some of them pray on their knees, others talk among them; on the right it is possible to see the pope and the emperor sitting on a pedestal, in frontal position; the pope, vested with the mitre, holds the crosier in his left hand while he blesses the bystanders with his right hand; at his feet, in addition to some crouched lambs and goats, it is possible to recognize two piebald dogs, that symbolize Dominican friars.
