"It's the first book which revisits Greek and Latin theories of signs from the point of view of a profound classical scholarship and a paramount knowledge of contemporary semiotics debates." —Umberto Eco

Available in English for the first time is Professor Manetti's brilliant study of the origin of semiotics and sign theory. He seeks to discover the common thread that runs through the classical world from the very beginning of human thought to the fourth century A.D. In the "classical" tradition he sees a concept of the sign which is significantly different from that currently in use.
