The last of three books by the famous Swiss scientist A. Bonnard, completing his brilliant study of Greek civilization. The third volume introduces the reader to the era of late antiquity - the time of the campaigns of Alexander the Great, the philosophy of Aristotle and Plato, the dramaturgy of Euripides, and the oratory of Demosthenes. This is the time of the expansion of Hellenic culture beyond the borders of Greece, the flourishing of science and the arts in the city of Alexandria, with which many Greek discoveries in mechanics, astronomy, geography, and medicine are associated. The book’s extensive material is concluded with chapters on Alexandrian poetry, the first Greek novel “Daphnis and Chloe,” the philosopher Epicurus and his teaching.
