Charles Kendall Adams,
Christopher Columbus: His Life and His Work
“ To visit the North, the West, or the South was not an enterprise of long duration; and the mariner who had explored the Black Sea, the Mediterranean, the Atlantic from the equator to Iceland and the Baltic, might well claim to be familiar with all the seas that were navigable to a European.Such were the most important of the experiences, which, so far as we can now know, gave form and fibre to the character of Columbus. If the years were full of turbulent experiences, it is evident that they were also years full of absorbing thought. ”
