The longer poem, entitled "Hercules Musagetes," is among the most admired of the author's pieces. His original poems equal in number, though not in excellence, those of his brother; for it would be absurd to expect that this universal genius should shine equally in every department of letters. The flexible, graceful, harmonious genius of Augustus William Schlegel has at different periods enriched his own tongue with the noblest literary treasures of ancient and modern Italy, of Portugal, Spain and England; and his immortal translations, which have superior merit to any original poems, but those of the highest order, are admitted by competent judges to have done more than the works of any writer, except Goethe, for improving the rhythm and poetical diction of his country. The great poetical powers which his short original pieces, as well as his translations, display, make it a matter of regret that he should have so much confined himself to translation, and never ventured on the composition of a great poem. Both these incomparable brothers are minds eminently poetical, and eminently philosophical. In one the poetic element prevails--in the other, the philosophical element, and, by a great deal, predominates. In their early productions we can scarcely discriminate the features of these apparently intellectual twins: but, as their genius ripens to manhood, the one becomes an etherial Apollo, full of grace, energy, and majesty--the other an intellectual Hercules, of the most gigantic strength and colossal stature. In was in the Spring of 1812 that Schlegel delivered, before a numerous and distinguished audience at Vienna, his lectures on ancient and modern literature. Of this work, which a German critic has characterised "as a great national possession of the Germans," and which has been translated into several European languages, and is so well known to the English reader by the excellent translation which appeared in 1818, it is unnecessary to speak at much length. Here were concentrated in one focus all those radii of criticism that this powerful mind had so long emitted. Here, at the bidding of a potent magician, the lords of intellect--the mighty princes of literature of all times--
