Il contributo dà conto di quanto rinvenuto
nelle ricognizioni condotte a nord ovest del
lago di Bracciano, alle sorgenti della Fiora e
riguardanti il primo tratto dell’Acquedotto
Traiano.
La ricostruzione si basa anche sui disegni
e le misurazioni condotte nel Seicento da Luigi Bernini e da Carlo Fontana, per recuperare
per Roma queste acque, le più ricche dell’intero invaso del lago.
Soprattutto i disegni di Carlo Fontana
hanno permesso di delineare un paesaggio e
una realtà idrica molto diversi dall’attuale, la
cui conoscenza ha permesso un fruttuoso confronto per ricostruire questo tracciato.
The paper is about what has been found
during the reconnaissance survey of the north-western area of Bracciano Lake, of the head of
the river Fiora area, and of the first segment
of the Aqua Trajana Aqueduct.
The reconstruction is based on the 16th
Century drawings by Luigi Bernini and Carlo Fontana, who also took the measurements.
They aimed to supply Rome with water from
the Aqueduct, which was much more abundant than the amount of water which was possible to obtain from the lake.
Above all, the drawings by Carlo Fontana
made clear that the whole landscape and the
water supply network were very different from
the modern one. The comparison between the
ancient and the modern network gave satisfying results that helped to reconstruct how
the ancient network actually was.
