Admiral of the Ocean Sea is Admiral Samuel Eliot Morison's classic biography of the greatest sailor of them all, Christopher Columbus. It is written with the insight, energy, and authority that only someone who had himself sailed in Columbus' path to the New World could muster. Morison undertook this expedition in a 147-foot schooner and a 47-foot ketch, the dimensions of these craft roughly matching those of Columbus' Santa Maria and Niña. The result is this vivid and definitive biography that accurately details the voyages that, for better or worse, changed the world.
