Quintus Curtius Rufus, History of Alexander 9.4.14

9.4.14

Findi crederes undas et retro gurgites cedere. Quibus tandem navis erepta non tamen ripae adplicatur, sed in proximum vadum inliditur. Cum amne bellum fuisse crederes. Ergo aris pro numero fluminum positis sacrificioque facto XXX stadia processit.

He had already stripped off his clothes preparatory to throwing himself into the river, while his friends were swimming about not far off ready to pick him up, but as it was evident that the danger was about equal whether he threw himself into the water or remained on board, the boatmen vied with each other in stretching to their oars, and made every exertion possible for human beings to force their vessel through the raging surges. It then seemed as though the waves were being cloven asunder. and as though the whirling eddies were retreating, and the ship was thus at length rescued from their grasp. It did not, however, gain the shore in safety, but was stranded on the nearest shallows. One would suppose that a war had been waged against the river. Alexander there erected as many altars as there were rivers, and having offered sacrifices upon them marched onward, accomplishing a distance of thirty stadia.
