A corbel bracket is a supporting element that uses corbelling to reach out horizontally from a vertical post to steady what is above. At Humayun's Garden Tomb, the material used to create corbel brackets is stone masonry stacked out and up at irregular intervals to appear organic and carved to resemble elaborately carved wood ornamentation, much like that of the local temple architecture. This feature is also prevalent in Sultanate architecture.
