This book, which Gustave Glotz was peculiarly well-equipped by all his previous work to write, has a twofold interest: on the one hand it traces, with remarkable erudition, the evolution of Greek institution, brings out their essential characteristics and, to a certain extent, enters into the details of their construction; and, on the other hand, it formulates and suggests the general ideas which such a subject admits of, and leads on to considerations of a sociological bearing. It combines strict realism and explanations of deep insight.
