In the civic buildings and palaces the Romans show the greatest constructive skill and splendour of embellishment. The skilful planning and appropriateness of decorative treatment in their basilicas and amphitheatres are evidences of the practical nature of the Romans. The Basilica or Hall of Justice was an important architectural feature, rectangular in plan, with a semi-circular apse at one end, where the Tribunal was placed; roofed with timber framing, or vaulted with concrete, and supported with rows of columns or biers. The remains of two typical Roman basilicas are still in existence: the Basilica of Trajan, A.D. 114, rectangular, 180 × 160 feet, five aisles, the centre aisle with a semi-circular wooden roof, and enriched with bronze plates, is typical of one class; and the basilica of Maxentinus, A.D. 310, with a width of 195 feet and a length of 260 feet, is typical of a vaulted Basilica, the two side aisles with an arched roof, and the centre aisle with an intersecting vaulted roof. These Roman basilicas were adopted by the early Christians to their service, and the basilica church was the typical form used up to the 12th century in the Romanesque provinces. [Illustration] The Roman houses were of two types: the _Domus_, or houses clustered together, and the _Insular_, houses which were surrounded by streets. Most of the finest Pompeian houses were of the _Insular_ type.
