Many parts are still unexplored, and scarce anything known of their extent, even by repute. Until Felix Aquila's time, the greater portion, indeed, had not even a name. Each community was well acquainted with the bay before its own city, and with the route to the next, but beyond that they were ignorant, and had no desire to learn. Yet the Lake cannot really be so long and broad as it seems, for the country could not contain it. The length is increased, almost trebled, by the islands and shoals, which will not permit of navigation in a straight line. For the most part, too, they follow the southern shore of the mainland, which is protected by a fringe of islets and banks from the storms which sweep over the open waters. Thus rowing along round the gulfs and promontories, their voyage is thrice prolonged, but rendered nearly safe from the waves, which rise with incredible celerity before the gales. The slow ships of commerce, indeed, are often days in traversing the distance between one port and another, for they wait for the wind to blow abaft, and being heavy, deeply laden, built broad and flat-bottomed for shallows, and bluff at the bows, they drift like logs of timber. In canoes the hunters, indeed, sometimes pass swiftly from one place to another, venturing farther out to sea than the ships. They could pass yet more quickly were it not for the inquisition of the authorities at every city and port, who not only levy dues and fees for the treasury of the prince, and for their own rapacious desires, but demand whence the vessel comes, to whom she belongs, and whither she is bound, so that no ship can travel rapidly unless so armed as to shake off these inquisitors. The canoes, therefore, travel at night and in calm weather many miles away from the shore, and thus escape, or slip by daylight among the reedy shallows, sheltered by the flags and willows from view. The ships of commerce haul up to the shore towards evening, and the crews, disembarking, light their fires and cook their food. There are, however, one or two gaps, as it were, in their usual course which they cannot pass in this leisurely manner; where the shore is exposed and rocky, or too shallow, and where they must reluctantly put forth, and sail from one horn of the land to the other. The Lake is also divided into two unequal portions by the straits of White Horse, where vessels are often weather-bound, and cannot make way against the wind, which sets a current through the narrow channel. There is no tide; the sweet waters do not ebb and flow; but while I thus discourse, I have forgotten to state how they came to fill the middle of the country. Now, the philosopher Silvester, and those who seek after marvels, say that the passage of the dark body through space caused an immense volume of fresh water to fall in the shape of rain, and also that the growth of the forests distilled rain from the clouds. Let us leave these speculations to dreamers, and recount what is known to be.
