Such subjects as the foregoing are often placed within an architectural structure, usually consisting of two pilasters and an entablature, sometimes surmounted by a pediment. Various theories have been proposed on the subject. It has been suggested that the architectural ornament indicates the votive character of the relief (_Journ. of Hellen. Studies_, v., p. 111), or the home of the dead person (Pervanoglu, _Grabsteine der alten Griechen_, p. 14), but there is no evidence of any such special significance attaching to the form. (Compare Furtwaengler, _Coll. Sabouroff_, i., p. 52.) _The Sepulchral Banquet._--From the fourth century onwards, a type of relief commonly known as the Sepulchral Banquet becomes very common in Attica and elsewhere. In a normal example of the fully developed type, the chief figure is that of a man recumbent on a couch, holding a cup. Before him is a table with food. A woman, according to Greek custom, is seated upright at the foot of the couch. Boys or attendants are seen drawing wine. The head of a horse is often seen at the back of the relief. A snake is frequently introduced, and often drinks wine from a cup held by one of the figures. Further, a group of adorant figures, usually on a small scale, may be represented about to sacrifice at an altar, near the foot of the couch. The meaning of this type has been a subject of long controversy, but it is best understood if the later reliefs are studied in connection with the oldest known specimens of the same subject. A series of archaic reliefs from the neighbourhood of Sparta (_Athenische Mittheilungen_, ii., pls. 20-25; Furtwaengler, _Coll. Sabouroff_, pl. 1; _Journ. of Hellen. Studies_, v., p. 123), contains subjects somewhat of the following character: A male and female figure, represented on a heroic or divine scale, are seated enthroned, holding as attributes a large two-handled cup, or a pomegranate. Figures of worshippers approach, carrying a pomegranate or a cock, and a snake is sometimes present. The sculptures of the Harpy Tomb (No. 94), have been sometimes classed with the works here described, but this has not yet been established.
