modillion

noun

1. A decoratively carved supporting block atop a column, often underneath a cornice, and usually smaller and more ornamental in function than a corbel.

   “It is a large square structure, two and a half stories in height, with a hipped roof rising above a handsome cornice with prominent modillions and surmounted by a balustraded belvedere.”

   “The familiar classic console or modillion is an example: although in general contour it is well adapted to its function as a supporting bracket, embedded in, and projecting from a wall, yet the scroll-like ornament with which its sides are embellished gives it the appearance of not entering the wall at all, but of being stuck against it in some miraculous manner.”
