It is possible that the Praefect may have continued to hold office down to the capture of Ravenna in May, 540, which made Witigis a prisoner, and seemed to bring the Ostrogothic monarchy to an end. Upon the whole, however, it is rather more probable that in the year 538 or 539 he finally retired from public life. The dates of his letters will show that there is nothing in them which forbids us to accept this conclusion; and the fact, if it be a fact, that in 540, when Belisarius, with his Secretary Procopius in his train, made his triumphal entry into Ravenna, the late Praefect was no longer there, but in his native Province of Bruttii, a little lessens the difficulty of that which still remains most difficult of comprehension, the entire omission from Procopius' History of the Gothic War of all mention of the name of Cassiodorus.

The Variae edited.

The closing years of the veteran statesman's tenure of office were years of some literary activity. It was in them that he was collecting, and to some extent probably revising, the letters which appear in the following collection. His motives for publishing this monument of his official life are sufficiently set forth in the two prefaces, one prefixed to the [First Book] and the other to the [Eleventh]. Much emphasis is laid on the entreaties of his friends, the regular excuse, in the sixth century as in the nineteenth, for an author or a politician doing the very thing which most pleases his own vanity. A worthier reason probably existed in the author's natural desire to vindicate his own consistency, by showing that the influence which for more than thirty years he had wielded in the councils of the Gothic Sovereigns had been uniformly exerted on the side of law and order and just government, directed equally to the repression of Teutonic barbarism and the punishment of Roman venality.

What alterations were made in the letters.

The question how far the letters which now appear in the 'Variae' really reproduce the actual documents originally issued by Cassiodorus is one which has been a good deal discussed by scholars, but with no very definite result. It is, after all, a matter of conjecture; and every student who peruses the following letters is entitled to form his own conjecture—especially as to those marvellous digressions on matters of Natural History, Moral Philosophy, and the like—whether they were veritably included in the original letters that issued from the Royal Secretum, and were carried over Italy by the Cursus Publicus. My own conjecture is, that though they may have been a little amplified and elaborated, substantially they were to be found in those original documents. The age was pedantic and half-educated, and had lost both its poetic inspiration and its faculty of humour; and I fear that these marvellous letters were read by the officials to whom they were addressed with a kind of stolid admiration, provoking neither the smile of amusement nor the shrug of impatience which are their rightful meed.

'Illum atque Illum.'

The reader will observe that in many, in fact most of the letters, which were meant to serve as credentials to ambassadors or commissions to civil servants, no names are inserted, but we have instead only the tantalising formula, 'Illum atque Illum,' which I have generally translated, 'A and B.' This circumstance has also been much commented upon, but without our arriving at any very definite result. All that can be said is, that Cassiodorus must have formed his collection of State-papers either from rough drafts in his own possession, or from copies preserved in the public archives, and that, from whichsoever source he drew, the names in that source had not been preserved: a striking comment on the rhetorical unbusinesslike character of the Royal and Imperial Chanceries of that day, in which words were deemed of more importance than things, and the flowers of speech which were showered upon the performer of some piece of public business were preserved, while the name of the performer was forgotten.

Treatise 'De Animâ.'

As soon as he had finished the collection of the 'Variae,' the Praefect—again in obedience to the entreaties of his friends—composed a short philosophic treatise on the Nature of the Soul ('De Animâ'). As he said, it seems an absurd thing to treat as a stranger and an unknown quantity the very centre of our being; to seek to understand the height of the air, the extent of the earth, the causes of storms and earthquakes, and the nature of the wandering winds, and yet to leave the faculty, by which we grasp all this knowledge, itself uncomprehended[72]. He therefore sets himself to enquire, in twelve chapters:
