Papal Coat of Arms - Symbolism and History of the Vatican’s Heraldry #3536359 (License: Personal Use)

This heraldic emblem represents the papacy during the pontificate of Leo X (Giovanni de’ Medici), combining traditional papal symbols-the triple tiara and crossed keys of St. Peter-with the distinctive Medici arms: six red roundels (palle) on a gold field and three golden fleurs-de-lis on a blue chief. The red and gold colors reflect Medici heritage, while the keys signify spiritual authority granted to Peter, and the tiara symbolizes the Pope’s triple role as Father, Pastor, and Teacher.

Used in Vatican publications, official documents, and historical resources about Renaissance popes; commonly sought by researchers, students, and Catholic audiences interested in ecclesiastical heraldry and Medici influence on the papacy.
