Tabulae totius dialectices, aliarum artium instrumenti ...

Marginalia: ...explained, and soon contracted into few words, and quickly spoken, as Horace preaches:
"Let docile minds perceive, and let faithful ones hold."

The main text continues the preface:
...explained, and soon contracted into few words, and quickly spoken, as Horace preaches:

Let docile minds perceive, and let faithful ones hold.

And we have recorded all these things accurately digested into tables: so that even voluntarily (while they are before their eyes daily) they might insinuate themselves into the familiarity of adolescents. To dedicate this labor to you, most prudent President, a man most eloquent and polished in every liberal science and even in interior letters, many learned men were urging me, shy and often somewhat rustically modest, to consecrate the first-fruits of my studies to your name, testifying to my soul and observance toward you. Wherefore I trust that you, for your highest humanity and usual benevolence toward those who are commended by some fame of erudition, will willingly accept this, whatever it is, which is offered, which I hope will be useful to studious adolescents and not useless to teachers: whereby the labor of teaching may be diminished in some part for them, and the method of learning may be made shorter and also more expeditious for the others. This convenience and utility of the new treatment, if there is any, and its ease, those who are studious ought to gratefully attribute to you, in whose name our tables are published. Farewell, at Utrecht. 10th day before the Kalends of June, 1545.
