Bondeno (river)(Natural Landmark)
Right tributary of Po, now partially disappeared.
"Casalis" in Massa Nautona donated by duke Hildebrand to Farfa in May 778 (CDL 4a:33) and later confirmed by Charlemagne in DKAR 1:111. In CDL 4a:37, April 783, mentioned as "Sucilianus ... in Massa Pretorii", territory of Rieti. Costambeys (2007), p. 75, argues they could be identical. Editor of CDL 5 locates it in a frazione of Collevecchio, province of Rieti
