1496–1527)[1] De Gregori (Latin: Johannes & Gregorius de Gregoriis) were two Italian brothers from Forlì who worked as printers in Renaissance Venice.
They are generally credited with the first attractive type in nonpareil size for a 1498[2] or 1501[3] edition of the divine offices.
Gregorio de Gregori is considered to have published the first book printed in Arabic, Kitab salat al-sawai—a book of hours—in 1514.
