or **Mantle tree**, in architecture, the lower part of the chimney, or that piece of timber which is laid across the jambs, and sustains the compartment of the chimney piece.

or **Mantling**, in heraldry, that appearance of folding of cloth, flourishing, or drapery, that is in any achievement drawn about the coat of arms. It is supposed originally to be the representation of a mantle, or military habit, worn by the ancient cavaliers over their armour to preserve it from rust; or, as others hold, a short covering only worn over the helmet, which in after-times was lengthened, and made to hang from the helmet below the whole shield. See Plate CX. fig. 1.
