Procopius (Goth. l. ii. c. 3) has forgot to
name these aqueducts nor can such a double intersection, at
such a distance from Rome, be clearly ascertained from the
writings of Frontinus, Fabretti, and Eschinard, de Aquis and
de Agro Romano, or from the local maps of Lameti and
Cingolani. Seven or eight miles from the city, (50 stadia,)
on the road to Albano, between the Latin and Appian ways, I
discern the remains of an aqueduct, (probably the
Septimian,) a series (630 paces) of arches twenty-five feet
high.
