Recent work on medieval Tuscania has included the study of the communal archives, notably by Don Lidano Pasquale, Luigi Pierdomenico and Giuseppe Giontella; publications on the architecture by Joselita Raspi Serra and others; and archaeological and topographical work carried out under the auspices of the British School at Rome. For the bibliography and archive sources, see Luttrell, 1971: 90–121; Whitehouse, et al., 1972: 196–238; add Ruysschaert, 1967–68, and Giontella, 1971–72. Some use has been made of the Libri del Consiglio which survive from 1449 onwards, but the registers of the Archivio Notarile e Giudiziario di Tuscania (now in the Archivio di Stato at Viterbo) have yet to be explored. Records of some nine notaries survive for the years 1457 to 1500; the materials are reasonably well written and preserved, and there is a detailed typescript index. This discussion merely presents one document from the earliest surviving register, that of Bartholomeo Thome, which is of particular interest as it shows that in 1458 the old civitas of Tuscania was considered to be ‘destroyed’ and ‘ruined’, and had become part of a rural tenimentum or tenuta. This document of 15 January 1458, published from Register 26 f.27–27v, refers to the Ciuitatis destructe et dirute. No attempt has been made to improve spelling or punctuation; the heavy contractions are often difficult to resolve, and significantly doubtful readings appear in square brackets. Another document at f.29–29v, which was drawn up four days later, concerns unum pectium terre situm in ten[imeri]to Ciuitatis tuscan[e] in Ciuitate deuastata et destructa.
