When on 28 April 1285 at Girona, during the Aragonese Crusade, Jean Cholet crowned Charles of Valois with his galero and pronounced him King of Aragon, he earned Charles the nickname roi du chapeau ("king of the hat").
When a cardinal dies, it is traditional that it be suspended over his tomb, where it remains until it is reduced to dust, symbolizing how all earthly glory is passing. It is said that when it falls, the cardinals soul has entered Heaven. In the United States, where only a few cathedrals have crypts, the galeri of past archbishops who were cardinals are suspended from the ceiling. Hence, St. Patrick's Cathedral, New York (where past archbishops are entombed beneath the sanctuary), Holy Name Cathedral in Chicago, Illinois,
the Cathedral Basilica of Saint Louis in St. Louis, Missouri, the Cathedral of Our Lady of the Angels in Los Angeles, California, and the Cathedral of St. Matthew the Apostle in Washington, D.C. are five Cathedral churches in the United States that hang the galeri of past Cardinals from their ceilings.
The galero (or "ecclesiastical hat") is still in use today in ecclesiastical heraldry as part of the achievement of the coat of arms of an armigerous Roman Catholic cleric. The galero replaces the helmet and crest, because those were considered too warlike for the clerical state. The color of the galero and number of tassels indicate the cleric's place in the hierarchy. Depiction in arms can vary greatly depending on the artist's style, but even when it looks like a cappello romano with tassels, in heraldry it is still considered a galero.
