Thybris ea fluvium, quam longa est, nocte tumentem leniit, et tacita refluens ita substitit unda, mitis ut in morem stagni placidaeque paludis sterneret aequor aquis, remo ut luctamen abesset.
All that night long Tiber calmed his swelling flood, and flowing back with silent wave so halted that like a gentle pool or quiet mere he smoothed his watery plain, so that the oars might know no struggle.
