One of the most dramatic periods in world history is the age of Europe's discovery of the world from Columbus and da Gama in the late 15th century to the voyages of James Cook in the 18th century. The extent of the changes can be seen by comparing the pre-Columbian maps, which showed no knowledge of either the Americas or the Pacific, with those of 1800, which in terms of projection, scale, and content approximate today's maps.

Richard Henry Dana, a law student turned sailor for health reasons, sailed in 1834 aboard the brig Pilgrim on a voyage from Boston around Cape Horn to California. Drawing from his journals, Two Years Before the Mast gives a vivid and detailed account, shrewdly observed and beautifully described, of a common sailor's wretched treatment at sea, and of a way of life virtually unknown at that time.
