biretta

"Diversity is necessary; it is indispensable," Francis said in his homily at the service, during which each new cardinal received a ring of office and the red, three-blade hat known as a "biretta".

It depicts a blurred, open-mouthed figure in a biretta, a traditional cap worn by Catholic clergy and wearing a politician's usual attire of a shirt and tie.

A photograph showed Bishop Joyce, in cassock and biretta, standing in front of a Christmas tree with children on each side.

A biretta is a stiff, four-cornered hat, topped with a big, fluffy tassel, that can be worn with a cassock and surplice!

Where the glowering Innocent X portrait radiates authority, Camillo appears softer and shier here, with a red biretta plopped on his head like a question mark.
