The Christopher Columbus Encyclopedia


Book Description

The European discovery of the Americas in 1492 was one of the most important events of the Renaissance, and with it Christopher Columbus changed the course of world history. Now, five hundred years later, this 2-volume reference work will chart new courses in the study and understanding of Columbus and the Age of Discovery. Much more than an account of the man and his voyages, The Christopher Columbus Encyclopedia is a complete A-Z look at the world during this momentous era. In two volumes, The Christopher Columbus Encyclopedia contains more than 350 signed original articles ranging from 250 to more than 10,000 words, written by nearly 150 contributors from around the world. The work includes cross-references, bibliographies for each article, and a comprehensive index. The work is fully illustrated, with hundreds of maps, drawings and photographs.
