Amit, Hirschfeld and Joseph Patrich (Jerusalem: Yad Izhak Ben-Zvi, 1989), pp. 101–108 (in Hebrew); The Ancient Reservoir of Sepphoris: Excavations, 1993–1994, Tsuk, E. Rosenberger and M. Peilstocker (Tel Aviv: National Parks, Hydrology Society and Ministry of Tourism, 1996) (in Hebrew); and “The Aqueducts to Sepphoris,” in Galilee Through the Centuries: Confluence of Cultures, ed., E.M.
