[126] In Subruino is the reading given in the text by Dederich. In suo rivo is the reading adopted by Polenus, Jocundus, and other editors. A third reading has been suggested, “In Simbrivio,” or in Simbruino, that is, referring to the Simbruine hills. This is the reading of Buecheler (1868), who follows verbatim the manuscript of Monte Cassino. The reading, however, bears little upon the evidence.
[127] Herculaneus Rivus. This is not the same Herculaneus Rivus as the one mentioned by Frontinus in connection with the Anio Vetus, in ch. 19. The same name is given in these places to different streams, all strong and rapid.
