Glossary

Term Definition
Arula A small altar composed of a rectangular or cylindrical body with an upper crown, for domestic use.
Balustrade slab (transenna) A vertical element inserted between columns to form a parapet (see Ward Perkins et al. 1986, 114). In the HoO the balustrade is always composed of two superimposed slabs – lower with base and upper with crown.
Worked block Block with a partially or fully carved, or incised surface. This can be directly on the stone or on its coating, and can be functional (e.g. mason’s or assembly marks) or decorative.
Column shaft A vertical cylindrical support, monolithic or composed of superimposed segments (higher than one and a half times its diameter) or drums (under or equal to one and a half times its diameter) (see Ginouvès et al. 1992, vol. 2, 78; Ward-Perkins et al. 1986, 132).
Furniture This category includes small stone fragments which can be identified as forming part of tables and basins, and the base of a thymiaterion.
Frame A moulded element that bordered objects or specific features of the building (doors, aediculae, pillars). They differ from cornices by their smaller dimensions and mainly decorative function. Very often the small size of a fragment does not permit identification of either the context or the object it relates to. The crown frames of balustrades are not included in this category.
Heart-shaped pier A corner vertical support composed of a square pillar and two attached (engaged or juxtaposed) half columns (see Ginouvès et al. 1992, vol. 2, 68; Ward Perkins et al. 1986, 113).
Pilaster A vertical rectangular/square/parallelepiped decorative element, protruding from the wall; monolithic or composed of superimposed blocks (see Ginouvès et al. 1992, vol. 2, 64).
Pillar A vertical rectangular/square/parallelepiped support, monolithic or composed of several superimposed blocks/segments. It can be free-standing or engaged (see Ginouvès et al. 1992, vol. 2, 63).
Simplified Corinthian capital Known also as ‘Nabatean’, ‘unfinished', ‘geometrized’, ‘stylized’ or ‘blocked-out’, the capitals are characterized by an intentionally schematic, geometric-like shape. Their designation derives from the similarity of their form to that of the standard Corinthian capitals.
Threshold Besides the well-recognized features in situ, this category also includes fragmentary examples in secondary use, or to blocks devoid of the characteristic features of a threshold (sockets, bolt-holes etc.), but identified as having this function because of their location in the building.
