ORLET, or Orlo, in architecture, a fillet under the ovolo, or quarter round of a capital. When it is at the top or bottom of a shaft, it is called cincture. Palladio uses the word orlo for the plinth of the basis of the columns.

ORLE, in heraldry, an ordinary, in form of a fillet, drawn round the shield, near the edge or extremity thereof, leaving the field vacant in the middle. Its breadth is but half that of the trellure or bordure, which contains a fifth part of the shield; and the orle only a twelfth: besides, that the orle is its own breadth distant from the edge of the shield, whereas the bordure comes the edge itself. The form of the orle is the same with that of the shield, whence it resembles an escutcheon. See Plate CXLIv. fig. 1. (a.)
