   • 1918, W. B. Maxwell, chapter 10, in The Mirror and the Lamp:

     It was a joy to snatch some brief respite, and find himself in the rectory drawing–room. Listening here was as pleasant as talking; just to watch was pleasant. The young priests who lived here wore cassocks and birettas; their faces were fine and mild, yet really strong, like the rector's face; and in their intercourse with him and his wife they seemed to be brothers.

   • 1956, Delano Ames, chapter 13, in Crime out of Mind‎:

     In one of the aisles there was an elaborately carved confessional box and I recognised the village priest in his heavy mountain boots and black cassock as he entered it and drew the dark velvet curtains behind him.
