of the deceased. This basic form, which served to identify the tomb owner, evolved into a key component of the funerary equipment with a magical function. Hence, from the 2nd Dynasty onward, the owner was usually shown seated before an offering table piled with food and drink; in the Middle Kingdom, the offering formula was generally inscribed along the top of the stele. Both were designed to ensure a perpetual supply of offerings in the afterlife. Votive stelae, inscribed with prayers to deities, were dedicated by worshipers seeking a favorable outcome to a particular situation. In the Middle Kingdom, many hundreds were set up by pilgrims on the "terrace of the great god" at Abydos, so that they might participate in the annual procession of Osiris. One particular variety of votive stele common in the New Kingdom was the ear stele, inscribed with images of human ears to encourage the deity to listen to the prayer or request. Commemorative stelae were produced to proclaim notable achievements (for example, the stela of Horwerra, recording a mining expedition to Serabit el-Khadim, and the Restoration Stela of Tutankhamun, celebrating the restoration of the traditional cults at the end of the Amarna period); to celebrate military victories (for instance, the Merneptah Stele); and to establish frontiers (for example the Semna stele of Senusret III and the boundary stelae around Amarna). Pyramidia A pyramidion is a capstone at the top of a pyramid. Called benbenet in ancient Egyptian language, it associated the pyramid as a whole with the sacred Benben stone. Pyramidia may have been covered in gold leaf to reflect the rays of the sun; in the Middle Kingdom, they were often inscribed with royal titles and religious symbols. Painting Not all Egyptian reliefs were painted, and less-prestigious works in tombs, temples and palaces were merely painted on a flat surface. Stone surfaces were prepared by whitewash, or if rough, a layer of coarse mud plaster, with a smoother gesso layer above; some finer limestones could take paint directly. Pigments were mostly mineral, chosen to withstand strong sunlight without fading. The binding medium used in painting remains unclear: egg tempera and various gums and resins have been suggested. It is clear that true fresco, painted into a thin layer of wet plaster, was not used. Instead, the paint was applied to dried plaster, in what is called fresco a secco in Italian. After painting,
