Main (Thompson) Library location: South wing -- Fifth window. Ottaviano Scotto (c. 1444 - c. 1499) was born to a noble family in Monza, a city in northern Italy. In 1479, he moved to Venice and printed his first book, an edition of the Diurnale Romanum. Scotto primarily worked on breviaries and collections of the writings of saints, including Jerome and Augustine. After his last independent publication in 1484, he turned his printing press over to Bonetus Locatellus and a guild of several heirs and apprentices. Scotto then spent the remainder of his career as an editor and publisher. The mark of Ottaviano Scotto consists primarily of an orb-and-cross motif. The orb is divided into two hemispheres; the upper contains the printer's initials, O.S., and the lower an uppercase M, which signifies Monza, his city of origin. Two horizontal bars intersect the line that extends upward from the orb to form a patriarchal cross. Scotto's successors continued to use this mark until the end of the 16th century.
