A period when the influence of Greece predominated succeeded the first epoch in the building of Rome, and to this time must be ascribed the adoption of the Greek models for public buildings, for circuses, baths, and basilicas. Ionic, Corinthian, and Doric columns were imported into Rome, the latter undergoing some modification to suit the Romans' more florid taste. The temples became Hellenic in style. The small _cella_ was built within an open court surrounded by arcades from which the people assisted at the sacrifices. The altar stood in the open court. Later, windows were introduced into the building, and the openings were filled in with a bronze grating similar to that still in perfect preservation over the door of the Pantheon, or with a perforated marble screen, fragments of coloured glass being inserted in the interstices of the pattern. By the third century there were 400 temples in Rome, but the simple form of the early buildings was hidden with excessive ornamentation, and frieze and cornice were loaded with carving and figures. The basilica, or kingly hall of justice, was a rectangular building divided into a central portion or nave and side aisles by rows of columns under a horizontal architrave. The columns were in two tiers, the upper one enclosing a gallery which was reached by a flight of stairs springing either within or without the building. The entrances were at the sides, and one extremity, and in some cases both were extended to form a semicircular apse or tribune where stood the judge's seat. A marble screen, the _cancellum_, separated this portion from the rest of the building, and this constituted the bar to which the accused were brought; just beyond stood the altar, where incense burned; and here, during the persecutions, Christians were arraigned and bidden to throw incense on the fire as a sign of recantation. These great buildings served as courts of justice and for the transaction of business, and those which stood upon the _fora_ were in some instances so large that several cases could be conducted in them at once. Before the Empire the nave was probably unroofed or covered only with an awning, and the upper galleries were entirely open so that their occupants could at will attend to the proceedings within the basilica or watch the games and events without. Similarly a single rail or low partition only separated the open colonnades below from the Forum. Curtains could be drawn across these to shut out importunate onlookers and to muffle the sounds of street traffic, but it is evident that the basilica precincts were regarded as a place of familiar _rendezvous_ by the idlers in the Forum, as the gaming tables scratched in the flooring of the Julian basilica testify.
