Circus, Gr. and R. (i. e. a circle). A flat open space near a city, round which were raised scaffoldings for the accommodation of the spectators. This was the form of the earliest circuses; but as civilization advanced, they were regularly constructed of stone. The arena was in the form of a vast rectangle terminating at one extremity in a semicircle, and surrounded by tiers of seats for the spectators. At the end fronting the semicircular part was a rectangular pile of buildings, underneath which were the carceres or stalls for the horses, and down the centre of the circus ran a long low wall called the spina, adorned with statues, obelisks, &c. This spina formed a barrier by which the circus was divided into two distinct parts, and at each end of it was a meta or goal, round which the chariots turned. (See Meta and Ovum.) The Romans constructed circuses in England, wherever they had a large encampment. The ruins exist at Dorchester, Silchester, Richborough, and other places.
Cirrus, R. (1) A lock of hair; a ringlet curling naturally, and so distinguished from the cincinnus, a curl produced by means of the curling-iron. (2) A tuft; the forelock of a horse when tied up above its ears. (3) A tuft of flowers forming a bunch or head, such as phlox, calceolaria, &c. (4) Light curled clouds in the sky, portending wind, are hence called cirri.
Ciselure, Fr. Chasing. (See Cælatura.)
Cissibium or Cissybium, Gr. and R. (κισσύβιον, i. e. made or wreathed with ivy). A drinking-vessel, so called because the handle was made of ivy-wood, or more probably because it had an ivy-wreath carved upon it.
Cissoid (lit. ivy-shaped). A celebrated curve, applied in the trisection of an angle, invented by Diocles the geometer.
Cissotomiæ, Gr. (κισσο-τόμοι, sc. ἡμέραι, i. e. the days of ivy-cutting). A festival held in Greece, in honour of Hebe, goddess of youth, and a youth called Cissos, who, when dancing with Bacchus, had fallen down and been changed into ivy. Accordingly at this festival youths and girls danced with their heads wreathed with ivy.
