On the night of April 3 they fought a pitched battle in the neighborhood of the Pantheon, the factions of Orsini and Colonna joining in the fray.

The fiercest emotions of the Renaissance find expression in the clenched teeth, strained muscles, knotted brows, and tense nerves, depicted by Pollajuolo with eccentric energy. We seem to be assisting at some of those combats a steccato chiuso wherein Sixtus IV. delighted, or to have before our eyes a fray between Crocensi and Vallensi in the streets of Rome.
