If it so happens that you have none to commune with, then God help you--and yours! In Treves you have not far to go in search of the Romans. Their _magnum opus_ confronts you boldly at the very threshold of the town. Solid and massive and symmetrical, it stands a pregnant lesson to the jerry-builders of to-day. There is little affinity indeed between the building methods of the ancient Romans and those of their trade whose sorry, pitiable record exists in the Quartiere Nuovo of Rome. About the Porta Nigra is no trace of stucco or rubble. The huge blocks of which it is built stand one upon the other clean-hewn and square. No signs of mortar are left, but we see marks of iron or brass clamps. Its colour is a warm, deep red, softened here and there by streaks of green. The Porta Nigra has passed through strange phases since first it started in life as a city gate. Obviously built for purposes of fortification, and equipped with towers of defence, its second phase was an ecclesiastical one, and the "spears" were indeed turned into "pruning-hooks" when the bellicose propugnaculum found itself transformed into a church. "Last scene of all, That ends this strange, eventful history." The gate was in 1876 finally cleared of priests and altars, and allowed to revert to its original form. Not far from the Porta Nigra stands the Cathedral, one of the oldest in Germany, archaeologically interesting, inasmuch as it owes its inception to the Romans. The Basilica, built by Valentinian as a court of law, is clearly traceable in the present cathedral, and one reads a strange tale of Romans and Franks in the sandstone and limestone and brick of its walls. Here is treasured the famous Heilige Rock, or holy coat worn by our Saviour when a boy. At rare intervals this garment is exhibited to the faithful, who come from all countries to gaze reverently upon it. Who that has seen can forget the last exposition in 1891? Never before or since has there been anything more pathetic than the sight of the long rows of tired, haggard, perspiring, praying pilgrims, who stood patiently for hours in the broiling August sun, moving only when permitted, and then at a snail's pace, towards their Mecca. Plebeian though the majority of faces were, their devotional, solemn, rapt expressions for the time being ennobled and beautified them. Treves during that time, however, was by no means the reposeful, dignified city it is to-day. Its buildings were defaced with flags and banners, its streets blocked with pilgrims, and the road leading from the station to the town was lined with booths, whose owners disposed quickly of such delicacies as Napfkuchen, Streusel-Kuchen, and Apfelwein. Piety and profit went everywhere hand-in-hand, and a roaring trade was done in rosaries and benitiers, the last made of the blue pottery of the country, and stamped with a representation of Leo XIII. against a background of Domkirche.
