[1] Speakers of the Ancient Egyptian language referred to pyramidia as benbenet [2] and associated the pyramid as a whole with the sacred benben stone.
[3] Pyramidia were usually made of limestone, sandstone, basalt or granite,[4][5] and were sometimes covered with plates of copper,[6] gold or electrum.
[3] Four pyramidia are housed in the main hall of the Egyptian Museum in Cairo: A badly damaged white Tura limestone pyramidion, thought to have been made for the Red Pyramid of Sneferu at Dahshur, has been reconstructed and is on open-air display beside that pyramid; it presents a minor mystery, however, as its angle of inclination is steeper than that of the edifice it was apparently built to surmount.
During the New Kingdom, some private underground tombs were marked on the surface by small brick pyramids that terminated in pyramidia.
The pyramidion of Mose (mes,s, New Kingdom, 19th Dynasty, c. 1250 BC, limestone, 53 cm tall) depicts himself making an offering, with his name on two opposite faces.
