Arete is a crucial concept in ancient Greek culture that defies simple translation. In general, it indicates excellence-especially of human beings, but also of animals, institutions, even objects. It is linked to important concepts such as glory, justice, truth and harmony. It influences important activities such as religion, athletics, politics, and education. This collection demonstrates the length and breadth of arete's importance in ancient Greek and Roman culture, from its prehistorical etymological roots to its mystification in pre-Christian theology and even its manifestation in the career of a modern archaeologist. Leaving aside Plato and Aristotle, to whom a companion volume has been dedicated, these essays explore arete in Presocratic philosophy, classical oratory, epinician poetry, tragic drama, ancient Sicilian history, Stoicism, Epicureanism, and Neoplatonic thought. To many, arete was inherited by blood from the Homeric heroes, a birthright of social elites used to reinforce traditional hierarchies in the classical polis. To others, arete was an achievement distinct from social advantage but expected to advantage society. To understand arete philosophically, we must explore its wider cultural function-and vice versa. Arete is an enduring-even ageless-concept that, properly understood, may benefit humanity even today.
