A sundial is a device that allows one to measure the time based on the where the sun’s shadow falls on its surface. The flat surface is usually marked with lines indicating the time of day, with a rod or triangular edge called a gnomon rising from the centre to create a shadow.

The wealthy Roman elite loved to decorate their houses and villas with lavish paintings, mosaics and artworks, particularly in the reception rooms where guests were entertained or clients received. Interior decoration followed changing fashions, but certain themes were always popular, including scenes of the gods and Greek mythology. Bacchus was commonly used in dining and entertaining rooms, Neptune and nymphs in the bathroom, Venus in the bedroom, and so on. The more exquisite and expensive the decoration, the higher the status of the owner; Romans loved to show off!
