On each side of the principal entrance rise two sculptured pyramids, charged with trophies of arms, both towards the faubourg, and towards the city. Underneath each of these pyramids is a small collateral passage for persons on foot. The arch is ornamented with two bas-reliefs: the one facing the city represents the passage of the Rhine; and the other, the capture of Maestricht. On the frieze on both sides LUDOVICO MAGNO was formerly to be read, in large characters of gilt bronze. This inscription is removed, and to it are substituted the word _Liberté, Égalité, Fraternité_. On arriving from Calais, you enter Paris by the _Porte St. Denis_. It was also by the _Porte St. Denis_ that kings and queens made their public entry. On these occasions, the houses in all the streets through which they passed, were decorated with silk hangings and tapestry, as far as the cathedral of _Notre-Dame_. Scented waters perfumed the air in the form of _jets d'eau_; while wine and milk flowed from the different public fountains. Froissard relates that, on the entrance of Isabeau de Bavière, there was in the _Rue St. Denis_ a representation of a clouded heaven, thickly sown with stars, whence descended two angels who gently placed on her head a very rich crown of gold, set with precious stones, at the same time singing verses in her praise. It was on this occasion that Charles VI, anxious for a sight of his intended bride, took a fancy to mix in the crowd, mounted on horseback behind Savoisi, his favourite. Pushing forward in order to approach her, he received from the serjeants posted to keep off the populace several sharp blows on the shoulders, which occasioned great mirth in the evening, when the circumstance was related before the queen and her ladies. Proceeding along the Boulevard towards the east, at a short distance from the _Porte St. Denis_, you arrive at the PORTE SAINT MARTIN. Although this triumphal arch cannot be compared to the preceding in magnificence, it was nevertheless executed by the same artists, having been erected in 1674. It is pierced with three openings, the centre one of which is eighteen feet wide, and the two others nine. The whole structure, which is fifty-four feet both in height and breadth, is rusticated, and in the spandles of the arch are four bas-reliefs; the two towards the city represent the capture of Besançon, and the rupture of the triple alliance; and those towards the faubourg, the capture of Lomberg, and the defeat of the Germans under the emblem of an eagle repulsed by the god of war. These bas-reliefs are crowned by an entablature of the Doric order, surmounted by an attic. The _Porte St. Martin_ is the grand entrance into Paris from all parts of Flanders.
