“Pragmatica” on the Ten Days of the Year


This work is the first known South American imprint. It consists of a four-page edict, issued by King Philip II of Spain, decreeing the change from the Julian to the Gregorian calendar. In order to bring the calendar back into line with the seasons, in February 1582 Pope Gregory XIII deleted ten days from the year 1582, so that October 4, 1582, of the Julian calendar was followed immediately by October 15, 1582, in the new Gregorian calendar. This work was produced in 1584 by Antonio Ricardo, an Italian typographer who worked as a printer in Mexico City and later moved to Lima, capital of the Viceroyalty of Peru, where he helped the Jesuits establish the first printing office in South America.
