In ad 79, the volcano Vesuvius erupted, burying the cities of Pompeii and Herculaneum under ash and rock, and leaving them remarkably well preserved for centuries. While Pompeii has been extensively written about and popularized, the remains of its sister city, a smaller yet wealthier community close to the sea, are less widely known, but they have yielded spectacular archaeological evidence. This is the first major study of Herculaneum since that of Joseph Jay Deiss, published in 1966 and last revised in 1993. And in any language there have only ever been a handful of books available, mostly guidebooks and exhibition catalogues. Herculaneum is based on the latest excavation work and incorporates much new material that has revolutionized our understanding of the site. The book draws on a decade's work with the Herculaneum Conservation Project which, thanks to the Packard Humanities Institute, has begun to reverse the neglect of previous years which had reduced this extraordinary site to a critical condition. Illustrated with more than 300 newly taken colour photographs and archive illustrations, plus eight spectacular 360-degree panoramas, it is the definitive overview for the general public of what we know and understand about Herculaneum, of what is still unknown and mysterious, and of the potential for future discoveries in both archaeological and political contexts.
