This collection of thematic chapters derives from inter-disciplinary research on the subject of Orte (Viterbo, Italy) from the earliest Etruscan occupation to the First Crusade in 1099. Written by scholars who have been heavily involved in excavations and conservation projects in Orte from the 1960s to 2003, the chapters examine the history and archaeology of the town in general, hydraulic systems, cemeteries, ceramics, metal and glass finds, bricks and brick-stamps and other finds.
