Macrobius, Saturnalia (Preface) 1-4
“My child Eustathius: nature has imbued our life with many different instincts, but none is greater than the force which binds us to our own children. She has made our need to educate you and raise you so powerful that parents can gain no greater pleasure–if everything goes according to plan–and feel no more savage sorrow, than when they fail. For this reason I have valued nothing more than your education and, because I believe that focused work should be preferred to prolonged diversion–I am intolerant of delays: I cannot wait for you to advance through only the studies you make tirelessly on your own, so I have also made an effort to read for you and to put together whatever I have read spread out among various volumes of Greek and Latin, before and since you were born as a total supplement of knowledge. And, just as if from your own pantry of culture, whenever you need some fact from history which evades other men by hiding in books, or you need to remember some famous deed or saying, it will be easy and efficient for you to find it.”
Multas variasque res in hac vita nobis, Eustachi fili, natura conciliavit: sed nulla nos magis quam eorum qui e nobis essent procreati caritate devinxit, eamque nostram in his educandis atque erudiendis curam esse voluit, ut parentes neque, si id quod cuperent ex sententia cederet, tantum ulla alia ex re voluptatis, neque, si contra eveniret, tantum maeroris capere possent.Hinc est quod mihi quoque institutione tua nihil antiquius aestimatur, ad cuius perfectionem compendia longis amfractibus anteponenda ducens moraeque omnis inpatiens non opperior ut per haec sola promoveas quibus ediscendis naviter ipse invigilas, sed ago ut ego quoque tibi legerim, et quicquid mihi, vel te iam in lucem edito vel antequam nascereris, in diversis seu Graecae seu Romanae linguae voluminibus elaboratum est, id totum sit tibi scientiae supellex, et quasi de quodam litterarum peno, si quando usus venerit aut historiae quae in librorum strue latens clam vulgo est aut dicti factive memorabilis reminiscendi, facile id tibi inventu atque depromptu sit.
