Gordon explains the background of each type of ship, how it was discovered (in the case of the older vessels), how it came to be in its current state, and why it matters. The author emphasizes the importance of each ship: did its discovery contribute to knowledge of a past civilization? What does it reveal about the politics, economics, and culture of the people who created it? Did its loss result in a significant change in maritime regulations, safety, and shipbuilding practices? These are the questions that defined Gordon’s choices, which demonstrate how maritime history is a significant part of world history. . . . Recommended.
