Both a remarkable work of scholarship and gorgeously produced portfolio of exquisite maps (two decades in the making and the result of a $4 million grant), this definitive atlas of the classical world is worth every penny of the hefty price. It features 99 color maps spread across 175 pages, indicating ancient sites, landscapes and populations in luminous, authoritative detail. The accompanying explanatory information is included on CD-ROM.  (GRE202, $468.75)
