What of the brilliancy of stones and gems, the gold that rolls amid the sands of rushing streams, the heaven-born fires that burst forth from the midst of the earth and even from the midst of the sea; the ocean itself, that binds land to land, dividing the nations by its threefold indentations, and boiling up with mighty rage? Swimming upon its waves, making them disturbed and swelling without wind, you will see animals exceeding the size of any that belong to the land, some clumsy and requiring others to guide their movements, some swift and moving faster than the utmost efforts of rowers, some of them that drink in the waters and blow them out again to the great perils of those who sail near them: you will see here ships seeking for unknown lands: you will see that man’s audacity leaves nothing unattempted, and you will yourself be both a witness and a sharer in great attempts.
