History

Galero

A galero (pl. galeri; L. galerum, pl. galera) in the Catholic Church is a broad-brimmed hat with tasselated strings worn by clergy. Over the centuries the red galero was restricted to use by individual cardinals while such other colors as green and violet were reserved to clergy of other ranks and styles.

History

The privilege of wearing the red galero was first granted to cardinals by Pope Innocent IV in 1245 at the First Council of Lyon. Tradition in the Archdiocese of Lyon is that the red color was inspired by the red hats of the canons of Lyon. Pope Innocent wanted his favorites to be distinct and recognizable in the lengthy processions at the council.

Anachronistically, some early Church Fathers are shown wearing a galero, notably Jerome frequently is pictured in art either wearing a galero, or with one close by. Even though the office of cardinal did not exist in Jerome's day, he had been secretary to Pope Damasus I, which in later days would have made him a cardinal ex officio.
