[Footnote 1: Games of strength. The public games of Greece were athletic and intellectual contests of various kinds. There were four of importance: the Olympic, held every four years; the Pythian, held every third Olympic year; and the Nemean and Isthmian, held alternate years between the Olympic periods. These great national festivals exercised a strong influence in Greece. They were a secure bond of union between the numerous independent states and did much to help the nation to repel its foreign invaders. In Greece the accomplished athlete was reverenced almost as a god, and cases have been recorded where altars were erected and sacrifices made in his honor. The extreme care and cultivation of the body induced by this national spirit is one of the most significant features of Greek culture, and one which might wisely be imitated in the modern world.] [Footnote 2: Troubadours. In southern France during the eleventh century, wandering poets went from castle to castle reciting or singing love-songs, composed in the old Provençal dialect, a sort of vulgarized Latin. The life in the great feudal chateaux was so dull that the lords and ladies seized with avidity any amusement which promised to while away an idle hour. The troubadours were made much of and became a strong element in the development of the Southern spirit. So-called Courts of Love were formed where questions of an amorous nature were discussed in all their bearings; learned opinions were expressed on the most trivial matters, and offenses were tried. Some of the Provençal poetry is of the highest artistic significance, though the mass of it is worthless high-flown trash.] [Footnote 3: At the time this oration was delivered (1837), many of the authors who have since given America a place in the world's literature were young men writing their first books. "We were," says James Russell Lowell, "still socially and intellectually moored to English thought, till Emerson cut the cable and gave us a chance at the dangers and glories of blue water."] [Footnote 4: Pole-star. Polaris is now the nearest conspicuous star to the north pole of the celestial equator. Owing to the motion of the pole of the celestial equator around that of the ecliptic, this star will in course of time recede from its proud position, and the brilliant star Vega in the constellation Harp will become the pole-star.]
