The transversal arch is twenty-five feet wide and fifty-seven feet high.

The general plan of this imposing monument is borrowed from that of the famous arches at Rome; but the transversal arch is an additional feature, while its reliefs, and inscriptions, and its colossal proportions throw the arches of Rome into comparative insignificance.

The interior sides of the piers are inscribed with the names of ninety-six victories; under the transversal arches are the names of generals.

We may define this attitude as a third transversal; that is to say, the free leg, instead of being behind as in the third, is impassive, so that the body, instead of being advanced, should be slightly inclined to one side.
