To the praise and honor of the Most High and Almighty God and of Mary his Virgin Mother there comes to an end Henricus de Piro on the Institutions, printed by Egidius van der Heerstraten in the bounteous University of Louvain, on the twelfth day of November. Lastly, masters and most beloved brothers, remember, I pray you, and silently in your minds consider with how great toils and how great harassments of the head I, Henricus, the son of Bruno, otherwise Henricus de Piro of Cologne, the least among the doctors and readers of the law, have completed this little work out of the writings of other men for your profiting and for the advancement of this new university of Louvain. Now I, day by day, after lecturing on the Pandects according to the terms of my public appointment, forthwith took up this work, though intolerably burdensome. Wherefore, my most courteous brethren, if you find any trace of error or anything worthy of correction, I request, pray, and entreat you, by your immortal souls, that you see to its correction and amendment in a kindly rather than a biting spirit, with the zeal of love rather than the spur of envy. To the praise of the Most High God, who lives and reigns, blessed to all ages. Amen. Even as late as 1580 an author, a musician this time, used the colophon to pour out the griefs of which nowadays we disburden ourselves in prefaces. It is thus that, in his “Cantiones seu Harmoniae sacrae quas vulgo Moteta vocant,” Johann von Cleve took advantage of the tradition of the colophon to bespeak the sympathy of students and amateurs of music for his troubles in bringing out his book: Sub calce operis, Musicae studiosos & amatores admonere, operae pretium visum est hoc Motetorum opus, primo Philippo Vlhardo, ciui et Typographo Augustano, ad imprimendum esse delegatum, qui ob aduersam corporis valetudinem (vt fieri solet) aequo morosior, saepe nostram intentionem non est assecutus, meque opus ipsum, praetermissis quibusdam mutetis (quae tamen breui, vita comite & Deo fauente, in lucem prodibunt) abbreuiare coegit, praesertim cum idem Typographus, opere nondum finito, diem suum clauserit extremum: ac deinceps idem opus Andreae Reinheckel, ad finem deducendum, sit commissum. Quare si quid, quod curiosum turbare posset occurrerit, Musici (oro) animam ferunt aequiore. Valete. Anno Domini M.D.lxxx. Mense Ianuario.
