in the strictest sense, a home or house for the dead; the term is applied loosely to all kinds of graves, funerary monuments, and memorials. In many primitive cultures the dead were buried in their own houses, and the tomb form may have developed out of this practice, as a reproduction in permanent materials of primeval house types. Thus prehistoric tomb barrows were usually built around a round hut, in which the body was placed, along with tools and other personal effects for use in the next life. With the more advanced technology of early civilizations, brick and stone tombs appeared, often of great size, but still preserving primitive house forms. They were sometimes domical and sometimes rectangular, depending on which form was in common domestic use when the tombs began to be built. Being thought of as houses, such tombs were often lavishly provided with clothes, utensils, and furniture, so that they are major sources of knowledge about the cultures that built them.

In very early times, royal dead were apparently provided not only with all manner of necessary objects but also with actual servants, who were put to death at the time of the burial so that they might continue to serve their master. Typical is the tomb of Queen Shub-Ad of Ur (Early Dynastic Period in Mesopotamia, c. 2900–c. 2334 BC), which contained the bodies of more than 60 attendants. It became more common, however, to substitute statues or painted images for human beings. This was the practice in most Egyptian (Egypt, ancient) tombs; and from such painted pictures and statuettes, particularly in Old and Middle Kingdom tombs, a vivid picture of Egyptian life can be gained.

In many cultures and civilizations the tomb was superseded by, or coexisted with, monuments or memorials to the dead; sometimes, as in ancient Greece, the bodies were burned and the ashes put in funerary urns. In medieval Christian thought, the tomb was considered an earthly prototype and symbol of a heavenly home. This concept appeared in the Roman catacombs, the walls of which were decorated with scenes of the resurrected in paradise. The church building itself sometimes functioned as a tomb (e.g., Hagia Sophia in Istanbul was the tomb of Justinian). Throughout the Middle Ages it was common to inter bodies in churches, monasteries, and chapels, with depictions of the deceased on carved or painted plaques, or as life-size gisants (reclining sculptured figures, usually lying on their backs) placed above them. The deceased were represented not as corpses but as souls living in heaven, with their hands pressed together in adoration and the symbols of their salvation beside them. During the 15th century it became a common Christian practice to represent such figures as dead (usually on biers). This foreshadowed a general revival of the Greek practice of erecting funerary monuments, rather than tombs, during the 16th century. Since the Renaissance, the idea in the West of the tomb as a home has died out, except as a faint reminiscence in the mausoleums sometimes erected above graves or serving as burial vaults in modern cemeteries.
