attendant on amalgamation with strange natives, as well as on a fresh distribution of land,—would have added greatly to our knowledge both of Greek character and Greek social existence. [101] Thucyd. i, 15. Taking the two centuries now under review, then, it will appear that there is not only no growing political unity among the Grecian states, but a tendency even to the contrary,—to dissemination and mutual estrangement. Not so, however, in regard to the other feelings of unity capable of subsisting between men who acknowledge no common political authority,—sympathies founded on common religion, language, belief of race, legends, tastes and customs, intellectual appetencies, sense of proportion and artistic excellence, recreative enjoyments, etc. On all these points the manifestations of Hellenic unity become more and more pronounced and comprehensive, in spite of increased political dissemination, throughout the same period. The breadth of common sentiment and sympathy between Greek and Greek, together with the conception of multitudinous periodical meetings as an indispensable portion of existence, appears decidedly greater in 560 B. C. than it had been a century before. It was fostered by the increased conviction of the superiority of Greeks as compared with foreigners,—a conviction gradually more and more justified as Grecian art and intellect improved, and as the survey of foreign countries became extended,—as well as by the many new efforts of men of genius in the field of music, poetry, statuary, and architecture, each of whom touched chords of feeling belonging to other Greeks hardly less than to his own peculiar city. At the same time, the life of each peculiar city continues distinct, and even gathers to itself a greater abundance of facts and internal interests. So that during the two centuries now under review there was in the mind of every Greek an increase both of the city-feeling and of the Pan-Hellenic feeling, but on the other hand a decline of the old sentiment of separate race,—Doric, Ionic, Æolic.
