For more than two millennia, the Parthenon has been revered as the symbol of Western culture, the epitome of the ancient society from which we derive our highest ideals. It was understood to honor the city-state's patron deity Athena, and its intricately sculpted surface believed to depict a celebration of civic continuity in the birthplace of democracy. But through a close reading of a lost play by Euripides, accidentally discovered on a papyrus wrapping an Egyptian mummy, Joan Connelly began to develop a new theory that has sparked one of the fiercest controversies ever to rock the world of classics. Now, she recounts how our most basic sense of the Parthenon and of the culture that built it may have been crucially mistaken. Re-creating the ancient structure from its natural environment to its pediment, and using a breathtaking range of textual and visual evidence, she uncovers a monument glorifying human sacrifice set in a world of cult rituals quite unlike anything conventionally conjured by the word "Athenian."
