Thecavea (Latin for "enclosure") are the seating sections ofGreek andRoman theatres andamphitheatres. In Roman theatres, thecavea is traditionally organised in three horizontal sections, corresponding to the social class of the spectators:^[1]

• theima cavea is the lowest part of thecavea and the one directly surrounding the arena. It was usually reserved for the upper echelons of society.
• themedia cavea directly follows theima cavea and was open to the general public, though mostly reserved for men.
• thesumma cavea is the highest section and was usually open to women and children.

Similarly, the front row was called theprima cavea and the last row was called thecavea ultima. Thecavea was further divided vertically intocunei. Acuneus (Latin for "wedge"; plural,cunei) was a wedge-shaped division separated by thescalae or stairways.

Cavea also referred to the subterranean cells in which the wild beasts were confined prior to the combats in the Roman arena.^[2]

Cavea is also the name for an experimental liquid rocket fuel, with the formal name 1,4,diaza,1,4,dimethyl,bicyclo 2,2,2, octane dinitrate which was researched as a monopropellant. The name Cavea refers to the cage-like arrangement of carbon atoms in the compound. There was a metyhlated variant of the compound with a lower freezing point that was named Cavea B. From there on the former Cavea was referred as Cavea A.^[3]
