RIVER TIBER, ROME'S FOUNTAIN OF LIFE
"The river widens considerably as it reaches the
sea and forms large bays, like the best sea harbours. And, most
surprising of all, it is not cut off from its mouth by a barrier
of sea sand, which is the fate even of many large rivers."
"Ships with oars,
however large, and merchantmen with sails up to 3,000 (amphorae)
capacity enter the mouth itself and row or are towed up to Rome;
but larger ships ride at anchor outside the mouth and unload and
reload with the help of river vessels."
(Dionysius of Halicarnassus)
