The modern town of Sutri lies 50 km. north of Rome, beside the Via Cassia, on the site of the ancient Sutrium (pl. X, a, b). It was already in existence in Etruscan times, passed to the Romans at the beginning of the fourth century b.c., was twice colonised by them and reached a peak of prosperity under the early Empire. It continued to flourish in the early Middle Ages, but a rapid decline set in after the fourteenth century and the town to-day is comparatively modest and unimportant.
The following report is concerned mainly with the ancient town and with a typical area of the surrounding countryside (7 km. × 12 km. in extent), as it was in Etruscan and Roman times (fig. 1, p. 64). It is chiefly a record of the archaeological remains found in the area during five months' fieldwork in the winter and spring, 1957–1958, undertaken as part of the British School's current programme of survey in southern Etruria, which is designed to record permanently such remains before they disappear for ever, as they are fast doing.
The antiquities of the ancient town itself are already well known and have been described several times in the past. But, apart from occasional references to isolated finds and an attempt towards the end of the last century to map the ancient roads, the countryside outside the town has never been properly explored. The bulk of the original work, therefore, lies in sections III and IV. The Etruscan and the Roman roads have been located, as far as is possible, and all the sites which are still to be found have been recorded. In certain areas present-day woodland concealed a few, notably round the small town of Bassano di Sutri and towards the summit of M. Calvi, south of Sutri, and cultivation in the immediate vicinity of the modern towns may have destroyed a few more, especially near Ronciglione; but at the most it is probable that only about 20 sites were lost or missed in this way, as opposed to a total recorded of some 220. Except for woodland, all the ground within the limits of the area chosen was walked over and examined.
