Plate XIV.

AQUEDUCTS

MARCIA AT PORTA TIBURTINA

CLAUDIA AND ANIO NOVUS AT ANGLE OF THE SESSORIUM

The upper view represents the stone specus of the Aqua Marcia at the Porta Tiburtina, now of S. Lorenzo, just within the gate, and in the wall on the southern side, with an opening by the side of it, through which a man can now walk into the specus and along it. To the right of this, still in the wall, is a Castellum of the Aqua Felice, which is here, as at the Porta Maggiore, above the Marcia, Tepula and Julia, and below the Claudia and Anio Novus.

In the lower view is the Claudia and Anio Novus, at the north-east angle of the gardens of the Sessorian Palace (now of S. Croce in Gerusalemme). One of the stone piers of the Aqua Claudia is seen just within the projection of the tower at the angle, which is an addition of a later period. Within this portion of the City wall is a great Castellum Aquæ, extending from the corner to the tower, through which the aqueducts entered Rome. The interior of the tower is a piscina, which is shewn in another plate.
