Should your research afford you a specialized expertise in the mathematicians of the first half of the sixteenth century, or should you perhaps recognize the paleography of the annotations presented below, I should be most gratified to receive your communication via the contact address provided at https://mardi.dk.

Gerrit Dou (1613-1675)
A learned monk – presumably from the sixteenth century. After a painting by Gerrit Dou (1613–1675).

The annotations are recorded within a specimen of:

Or, rendered into formal English:

The Works of Euclid of Megara—most acute Philosopher and undisputed Prince of all Mathematicians—as translated by the most faithful interpreter, Campanus. In former times, on account of the execrable negligences of copyists, these Works were so defiled by loathsome errors that one would scarcely have recognized Euclid himself. Luca Pacioli, a distinguished theologian possessing the most profound mastery of the mathematical disciplines, has, with the most rigorous judgment, cleansed and emended the text. The one hundred and twenty-nine figures, which in other manuscripts were transposed or corrupted, he has restored to their proper symmetry and supplemented with many necessary additions. The manifold passages where the text proved obscure he has elucidated and clarified with concise, learned commentaries. To ensure the work was issued in its most refined state, Scipio Vegius of Milan—renowned for his mastery of both languages, the medical arts, and higher studies—has contributed his own diligence and critical review. A. Paganius Paganinus has, with the utmost precision, printed this work with the most elegant typefaces.

Euclidis megarensis
The reproduced title page originates from the specimen held at the Linda Hall Library, Kansas City, Missouri, and corresponds exactly to the title page of the copy described herein.

The volume consists of 146 leaves, the final leaf of which is blank. It is bound in contemporary vellum, with the title Euclidis Campani inscribed in ink on the upper cover. There are no recorded names of previous owners. The colophon on fol. 145v specifies the place of publication and the date: “Ve.Re.Pu. M.D.VIIII. Klen. xi. Iunii.” (Republic of Venice, June 11, 1509—alternatively calculated as May 22, 1509, in accordance with the Julian to Gregorian conversion).
