To return to ancient times, we find an absorbingly interesting link with pre-Christian days sculptured on one of the panels which decorate the interior of the Arch of Titus. The Via Sacra passed under this arch, which was erected to commemorate the taking of Jerusalem. The panel in question has figured on it in bas-relief a procession bearing the seven-branched candlestick and tabernacle which were spoils from the Jewish Temple. This is the only known material proof existing of the former object, and may therefore be justly said to be of surpassing ecclesiastical interest. Through the archway one sees the half-ruined walls of the Colosseum, the greatest amphitheatre in the world. This, too, is of intense religious interest. In the arena hundreds of Christian martyrs were torn to pieces by wild beasts, or butchered to fill the passing hours with amusement for the Roman populace. Pope Benedict XIV. consecrated the interior after erecting gates outside to preserve it from the demolition which up to his day had been going on for centuries. Small chapels were also formed amongst the lower structural arches, and services held where once the walls resounded to the shouts of bloodthirsty spectators. Close by the Colosseum is another fine archway, the Arch of Constantine. This likewise, has an interest apart from its design. It was put up when the great emperor declared himself in favour of the Christian faith. The devout may ponder over the fact that these two arches, so closely connected with Christianity, are still standing, while nearly every other has long since been razed to the ground.
Away to the south-east of these three buildings the Mother Church of Rome is situated close to the city walls. Here, on rising ground, overlooking the vast Campagna, stands S. Giovanni in Laterano, "omnium urbis et orbis ecclesiarum mater et caput." Dedicated originally to Christ the Saviour, and afterwards in the sixth century to S. John, this fine basilica is of much greater, archæological interest than S. Peter's. The present building dates from the seventeenth century. All that remains of the once attached Benedictine monastery is to be found in the very beautiful cloisters, which are a transition between Romanesque and Gothic. The church itself has a fine eastern façade--it orientates to the west--of five arches with an intervening gallery. In the _atrium_ is a statue of Constantine found in his _Thermæ_. The interior of the basilica is simple, with a very good _opus Alexandrinum_ floor. The aisles are double, and are separated from the nave by eleven bays on each side. Colossal statues of Apostles and Prophets find places at the bases of the pillars. The transepts and tribune are raised above the body of the church. In the centre, the high altar is situated under an ornate Gothic canopy. This contains a tabernacle, erected partly at the expense of Charles V. of France, to receive the busts of SS. Peter and Paul which were found amidst the ruins of the older church. A few years ago the tribune was extended and beautifully inlaid with mosaic carrying out a design of the thirteenth century. Michael Angelo is said to have designed the flat ceiling of the nave, and there is a wooden figure of S. John by Donatello in the sacristy.
