Etymology 2
According to Zosimus, the place “was called Rhene because it is surrounded by waters flowing throughout and on all sides” (Ῥήνη κληθεῖσα διὰ τὸ πανταχόθεν ὕδασι περιρρεῖσθαι — ), referring to Ravenna’s original character as a settlement comprising buildings erected on piles on numerous small islands in a marshy lagoon. Compare the verb, the noun , and the contraction of the Titaness’s name , which  derives from the verb.
