The is the first edition of Christoph Clavius's justly celebrated commentary on Euclid, one of the foundational mathematical books of the Renaissance and among the most influential editions of the Elements ever published.

E. J. Dijksterhuis — “Clavius’s edition of Euclid became the standard textbook of geometry for more than a century.”

Michael J. Crowe — “The most influential edition of Euclid in the Renaissance was that of Christoph Clavius.”

William A. Wallace — Clavius was “the most influential mathematical educator of the late sixteenth century.”

In short: “Clavius did for Euclid what later commentators did for Aristotle: he created the authoritative Renaissance version through which generations learned the discipline.”
