In architecture, a modillion is an ornate bracket, more horizontal in shape and less imposing than a corbel. They are often seen underneath a cornice which helps to support them. Modillions are more elaborate than dentils. All three are selectively used as adjectival historic past participles as to what co-supports or simply adorns any high structure of a building, such as a terrace of a roof, parapet, pediment/entablature, balcony, cornice band or roof cornice. Modillions occur classically under a Corinthian or a Composite cornice but may support any type of eaves cornice. They may be carved or plain.
