Chess rooks frequently occur as heraldic charges. Heraldic rooks are usually shown as they looked in medieval chess sets, with the usual battlements replaced by two outward-curving horns. They occur in arms from around the 13th century onwards. In Canadian heraldry, the chess rook is the cadency mark of a fifth daughter.
