One of the women has her hand on the arm of a chained warrior, and the other has at her feet military trophies; among which bucklers, arms, and trumpets, may be seen.

The pilasters that bound the intercolumniations are of the Doric order, and their capitals support the arch.
The cornice and astragals form a frieze, in which military emblems and symbols of sacrifice are intermingled.

The archivault is ornamented on each side with sculptured wreaths of ivy, pine cones, branches of grapes and olives, interlaced with ribands.

The ceiling of the portico is divided into hexagons and squares, enriched by various designs in the shape of eggs and roses, finely executed.
This interesting monument appears to have been ornamented with equal care and richness on every side, but its decorations have not enabled any of the numerous antiquaries who have hitherto examined it to throw any light on its origin; and the destruction of its architecture must have caused that of its inscription, if, indeed, it ever bore one.
The mausoleum is even more curious than the arch, as being the only building of a similar character of architecture to be seen.
Placed on a large square pediment, approached by two steps, the edifice rises with unequalled lightness and beauty against the blue sky, forming two stages supported by columns and pilasters, united by a finely sculptured frieze.

The first stage retreats from the pediment; and the second, which is of a round form, and terminated by a conical-shaped top, is less in advance than the first, giving a pyramidal effect.
The four fronts of the pediment are nearly covered by bassi-relievi, representing battles of infantry; the figures of which are nearly as large as life, and admirably designed.
On the north front is a combat of cavalry; on the west, an engagement, in the midst of which the body of a man is lying on the ground, one party of soldiers endeavouring to take possession of it, while another band of soldiers are trying to prevent them.
The basso-relievo of the south front represents a field of battle, strewed with the dead and wounded, and mingled with warriors on horseback and on foot.
