A nun is a woman dedicated to the severer duties of religion, secluded in a cloister from the world, and debarred by a vow from the converse of men. When a woman is to be made a nun, the habit, veil, and ring of the candidate, are carried to the altar; and she herself, accompanied by her nearest relations, is conducted to the bishop, who, after mass and an anthem (the subject of which is, "that she ought to have her lamp lighted, because the bridegroom is coming to meet her,") pronounces the benediction: then she rises up, and the bishop consecrates the new habit, sprinkling it with holy water. When the candidate has put on her religious habit, she presents herself before the bishop, and sings on her knees, Ancilla Christi sum, etc.; then she receives the veil, and afterwards the ring, by which she is married to Christ; and lastly, the crown of virginity.
