Res Gestae

Now the entire Pontus throughout its whole circuit is misty,[*](Cf. Mela, i. 19, 102, brevis, atrox, nebulosus, etc.) has sweeter[*](I.e. fresher. ) waters than the other seas,[*](Cf. Sail., Hist. iii. 65, Maur., mare Ponticum dulcius quam cetera; Val. Flacc. iv. 719 ff.) and is full of shoals, since the air is often thickened and condensed from the evaporation of moisture, and is tempered by the great masses of water that flow into it; and, because the many rivers that pour into it from every side bring in mud and clods, it rises in shoals that are full of ridges.
