An ancient Greek open-air running track and sports ground, providing for spectators by raised earth banks. The stadium was shaped like a hairpin, one end curved and the other, the starting point, either open as at Athens and Delphi, or squared as at Olympia. In the Roman period, stone seating was normal. Occasionally, as at Nicopolis, a Roman stadium was rounded at both ends. The standard length was 600 feet which gave a straight course for the sprint race of about 200 yards. The two-grooved starting line is seen at Corinth (in the agora), Delphi, and Olympia; postholes indicate a separation of the runners at the start.

Essentially glass which has been coloured either through painting the surface with translucent material or, more commonly, adding elements to the glass during its production to give a permanent tint. From about the 12th century onwards pieces of cut and shaped coloured glass were joined together in lead frames to produce pictures of scenes, events, and motifs that were put into windows. Mainly used in ecclesiastical architecture, by the 14th century and on into the Renaissance, stained-glass windows were being treated much like a painter's canvas.
