WHAT DO WE KNOW ABOUT THE CELTS?

The catechism-style queries heading the 17 topical spreads here may seem a bit off-putting, but they're an admirably direct approach to information and subjects likely to interest children- -not only concerning ``what'' is known, but how the surviving evidence can be interpreted. On each spread, a brief paragraph addresses the question at hand (``Did the Celts go shopping?...[not] like we do. Instead, they grew their own food...However, luxury goods such as jewelery [sic] were bought...''). Extensively captioned photos and drawings of artifacts and reconstructions amplify the information on crafts and trade, origins and tribal movements, family structure, beliefs, and more. Like a well-crafted exhibit, an inviting introduction that offers a good sampling of objects with real stories to tell, together with lucid explanations of how these can be read (Martell even cautions that contemporary descriptions of Celts ``were written by people who thought their civilizations were better than the Celtic one,'' and gives an egregious example from Julius Caesar).
