The cassock, an ankle-length robe worn by Christian clergy, has functioned as a symbol of religious identity and tradition across various denominations, from Catholicism to Anglicanism. Historically descended from ancient tunics, it developed into a liturgical essential, characterized by its fastenings, hues, and designs that signify the wearer’s status. Although its regular use has decreased in favor of clerical suits, the cassock continues to play a central role in ceremonial dress, as demonstrated by the detailed accounts of its variations and symbolic meanings.
In literature, it appears both as a setting—Virginia Woolf evoking the solemnity of a church filled with "cassocks in place"—and as a character name, as in Horace Bleackley’s A Clerical Error, where "Mr. Cassock" becomes a narrative figure. These mentions highlight its dual function as both a liturgical object and a cultural symbol, connecting religious practice with literary imagination.
