(4) Of a different quality, though still partaking somewhat of the nature of a compilation, was his chief educational treatise, the 'Institutiones Divinarum et Humanarum Lectionum[85].' About the year 543, some three or four years after his retirement from public life, while he was slowly ploughing his way through the Commentary on the Psalms, twenty of which he had already interpreted, he seems to have laid it aside for a time in order to devote himself to this work, which aimed more at instruction than at religious edification. In the outset of this book he describes that unsuccessful attempt of his, to which allusion has already been made, for the establishment of a theological school in Rome, and continues that, 'as the rage of war and the turbulence of strife in the Italian realm[86] had prevented the fulfilment of this desire, he felt himself constrained by Divine charity to write for his monks' behoof these _libri introductorii_, in which, after the manner of a teacher, he would open to them the series of the books of Holy Scripture, and would give them a compendious acquaintance with secular literature.' As the book is not written for the learned, he undertakes to abstain from 'affectata eloquentia,' and he does in the main keep his promise. The simple, straightforward style of the book, which occasionally rises into real and 'unaffected eloquence' where the subject inspires him to make an appeal to the hearts of his readers, presents a striking and favourable contrast to the obscure and turgid phraseology in which the perverted taste of the times caused him generally to shroud his meaning[87]. [Footnote 85: Printed hitherto as two works, De Institutione Divinarum Litterarum, and De Artibus ac Disciplinis Liberalium Litterarum. But, as Ebert has shown (i. 477), the Preface to the Orthographia makes it probable that these two really formed one book, with a title like that given above.] [Footnote 86: 'In Italico regno.' These words seem to favour the conjecture that Theodoric may have called himself King of Italy.] [Footnote 87: As a specimen of this better style of Cassiodorus, I may refer to his praises of the life of the literary monk, and his exhortation to him who is of duller brain to practise gardening: 'Quapropter toto nisu, toto labore, totis desideriis exquiramus ut ad tale tantumque munus, Domino largiente, pervenire mereamur. Hoc enim nobis est salutare, proficuum, gloriosum, perpetuum, quod nulla mors, nulla mobilitas, nulla possit separare oblivio; sed in illa suavitate patriae, cum Domino faciet aeterna exsultatione gaudere. Quod si alicui fratrum, ut meminit Virgilius, "Frigidus obstiterit circum praecordia sanguis," ut nec humanis nec divinis litteris perfecte possit erudiri, aliqua tamen scientiae mediocritate suffultus, eligat certe quod sequitur, "Rura mihi et rigui placeant in vallibus amnes."
