The reason why a theory founded on such an absurdly weak basis has held its ground at all, has probably been that it buttressed up another obvious fallacy. A whole school of biographers of Cassiodorus and commentators on his works has persisted, in spite of the plainest evidence of his letters, in identifying him with his father, who bore office under Odovacar (476-493). To do this it was necessary to get rid of the date 480 for the birth of Cassiodorus Senator, and to throw back that event as far as possible. And yet, not even by pushing it back to 468, do they make it reasonably probable that a person, who was only a child of eight years old at Odovacar's accession, could in the course of his short reign (the last four years of which were filled by his struggle with Theodoric) have held the various high offices which were really held during that reign by the father of Senator. We assume therefore with some confidence the year 480 as the approximate date of the birth of our author; and while we observe that this date fits well with those which the course of history induces us to assign to his ancestors in the three preceding generations[14], we also note with interest that it was, as nearly as we can ascertain, the year of the birth of two of the most distinguished contemporaries of Cassiodorus--Boethius and Benedict. [Footnote 14: Cassiodorus the First, born about 390; the Second, about 420; the Third, about 450.] [Sidenote: Education of Cassiodorus.] Of the training and education of the young Senator we can only speak from their evident results as displayed in the 'Variae,' to which the reader is accordingly referred. It may be remarked, however, that though he evidently received the usual instruction in philosophy and rhetoric which was given to a young Roman noble aspiring to employment in the Civil Service, there are some indications that the bent of his own genius was towards Natural History, strange and often laughable as are the facts or fictions which this taste of his has caused him to accumulate.
