Note 2655 — BOOK XXXVI. THE NATURAL HISTORY OF STONES.

The Aqua Marcia was brought a distance of upwards of 60 miles, from the vicinity of Sublaqueum, now Subiaco, and was of such elevation that water could be supplied to the loftiest part of the Capitoline Hill. A considerable number of the arches are still standing. In the vicinity of the city it was afterwards united with the Aqua Tepula and the Aqua Julia; the watercourse of the last being above that of the Aqua Tepula, and that above the course of the Aqua Marcia. See B. xxxi. cc. 24, 25.
