About the Cover


Parthenon in Athens, made of white marble from Mount Pentelikon. The pediment sculptures (now in the British Museum) depicted the birth of Athena Parthenos, the virgin goddess, and her battle with Poseidon for the land of Greece. Isotopic studies of such marbles reveal the localities from which they were quarried in ancient times. See page 401. [R. F. Weiss, University of California, San Diego]
