Printers' mark of Abraham Usque [16th century; born, Portugal - died, Ferrara, Italy (?)], a printer in Ferrara between 1553 and 1558 who was best known for the "Ferrara Bible," the first printing in Spanish of the Bible. Usque's activity was directed towards guiding former Conversos back to Judaism. Usque, himself born and baptized "Duarte Pinel," fled Portugal as a Converso in 1543.
