were composed at the time when the fair copy of Troilus had just been finished, and may be dated, without fear of mistake, in 1381-3. It is not likely that we shall be able to determine these dates within closer limits; nor is it at all necessary that we should be able to do so. A few further remarks upon this subject are given below. § 2. BOETHIUS. Before proceeding to remark upon Chaucer's translation of Boethius, or (as he calls him) Boece, it is necessary to say a few words as to the original work, and its author. Anicius Manlius Torquatus Severinus Boethius, the most learned philosopher of his time, was born at Rome about A. D. 480, and was put to death A. D. 524. In his youth, he had the advantage of a liberal training, and enjoyed the rare privilege of being able to read the Greek philosophers in their own tongue. In the particular treatise which here most concerns us, his Greek quotations are mostly taken from Plato, and there are a few references to Aristotle, Homer, and to the _Andromache_ of Euripides. His extant works shew that he was well acquainted with geometry, mechanics, astronomy, and music, as well as with logic and theology; and it is an interesting fact that an illustration of the way in which waves of sound are propagated through the air, introduced by Chaucer into his House of Fame, ll. 788-822, is almost certainly derived from the treatise of Boethius _De Musica_, as pointed out in the note upon that passage. At any rate, there is an unequivocal reference to 'the felinge' of Boece 'in musik' in the Nonnes Preestes Tale, B 4484. § 3. The most important part of his political life was passed in the service of the celebrated Theodoric the Goth, who, after the defeat and death of Odoacer, A. D. 493, had made himself undisputed master of Italy, and had fixed the seat of his government in Ravenna. The usual account, that Boethius was twice married, is now discredited, there being no clear evidence with respect to Elpis, the name assigned to his supposed first wife; but it is certain that he married Rusticiana, the daughter of the patrician Symmachus, a man of great influence and probity, and much respected, who had been consul under Odoacer in 485. Boethius had the singular felicity of seeing his two sons, Boethius and Symmachus, raised to the consular dignity on the same day, in 522. After many years spent in indefatigable study and great public usefulness, he fell under the suspicion of Theodoric; and, notwithstanding an indignant denial of his supposed crimes, was hurried away to Pavia, where he was imprisoned in a tower, and denied the means of justifying his conduct. The rest must be told in the eloquent words of Gibbon[1].
