DEDICATORY LETTER.

BERNHARDUS FULLENIUS, U. J. D. Doctor of Both Laws Professor of Mathematics at the University in Franeker,

FRANCISCUS FULLENIUS, U. J. D. Doctor of Both Laws Burgomaster and Councilor of the city of Franeker, and currently Muster-Commissioner of the Noble and Mighty Lords of the States of Friesland.

A decorative woodcut initial 'D' featuring scrolled vine patterns and floral elements.

Those who were the first to dedicate their books, written for the public good, to specific persons, chose for that purpose, as far as I can learn, those who were closest to them; and worthy of the honor of decorating a useful work with their names. And everyone must admit that it is beyond reproach if one proves their gratitude by giving at least as much honor to someone whom one cannot repay as it is to openly profess the benefit and friendship. Thinking well on this, I have no one closer than you both, dear and beloved Brothers: because benevolence and friendship go together here in the greatest measure. For the father of you both, Master BERNHARDUS FULLENIUS, of praiseworthy and blessed memory, was first a fellow student with my own father, thereafter the successor of the famous man Sixtinus Amama, and since then of the widely renowned Metius: he has heard me declare with respect more than once that I recognized His Honor, along with Master Jacob Alting, as my greatest and most faithful Masters, to whom I must be indebted for all my life.
