a person who wears a calotte (“religious skullcap”); any officer of the church
“Lorsqu'il lisait les grands morceaux, il était transporté; mais, quand il songeait que les calotins en tiraient avantage pour leur boutique, il était désolé, et dans cette confusion de sentiments où il s'embarrassait, il aurait voulu tout à la fois pouvoir couronner Racine de ses deux mains et discuter avec lui pendant un bon quart d'heure.” — When he read the fine passages he was transported, but when he thought that mummers would get something out of them for their show, he was disconsolate; and in this confusion of sentiments in which he was involved he would have liked at once to crown Racine with both his hands and discuss with him for a good quarter of an hour.
From calotte + -in.
