Philodemus’ History of the Academy represents a valuable treatise on Greek philosophical schools containing much unique information on Plato and on the development of the Academy under his successors. The so called Index Academicorum is a draft version preserved in a Herculaneum papyrus, which has been reread and reedited on the basis of innovative papyrological criteria and pioneering imaging techniques. The text is now very different from former editions and reveals countless new facts on various Academic philosophers. The edition provides new insights of interdisciplinary relevance into ancient philosophy, biography, literature and the ancient process of writing a book.
