[German version]

In Roman culture, aedicula either refers to a cult-related shrine ( Lararium), often in a sepulchral context ( Tombs), which contained urns or pictures of the deceased, or a building structure flanked by columns for the housing of statues or paintings. In the latter case either as an individual building usually placed on a podium as high as a man or as a niche integrated into a façade arrangement. Rear and side walls are without windows, the roof with a flat slope has a gable displaying ornaments. The  naiskos is comparable in Greek culture.
