[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. [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." [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. [5] It is now a well-recognized fact in the development of animal life that as any part of the body falls into disuse it in time disappears. Good examples of this are the disappearance of powerful fangs from the mouth of man, the loss of power in the wings of barnyard fowls; and, vice versa, as new uses for a member arise, its structure changes to meet the new needs. An example of this is the transformation from the hoof of a horse through the cloven hoofs of the cow to the eventual development of highly expert fingers in the monkey and man. Emerson assumed the doctrine of evolution to be sufficiently established by the anatomical evidence of gradual development. In his own words: "Man is no up-start in the creation. His limbs are only a more exquisite organization—say rather the finish—of the rudimental forms that have been already sweeping the sea and creeping in the mud. The brother of his hand is even now cleaving the arctic sea in the fin of the whale, and innumerable ages since was pawing the marsh in the flipper of the saurian." A view afterwards condensed into his memorable couplet: "Striving to be man, the worm Mounts through all the spires of form." [6] Stint. A prescribed or allotted task, a share of labor. [7] Ridden. Here used in the sense of dominated. [8] Monitory pictures. Instructive warning pictures.
