Giacomo Mazzocchi

Giacomo Mazzocchi, a native of Bergamo, was a bookseller, printer, and noted antiquarian in papal Rome during the High Renaissance.

Mazzocchi is first heard of in 1505 as publisher of an edition of Vibius Sequester De fluminibus printed by J. Besicken of Rome. By 1509 Mazzocchi was himself in business as a printer, printing mostly scholarly works for the circle of Roman humanists. He also published, under papal privilege, many papal bullae including those of the Fifth Lateran Council. As a printer he is interesting for he was among first to use a large-format upper-case roman typeface for title-pages, headings and other prominent lines.

It is presumed that Mazzocchi disappeared during the Sack of Rome in 1527 by the troops of Charles V, Holy Roman Emperor (r. 1519 – 1556).
