Print, Perpetual Calendar

This is a Print. It was designed by Ortensio Toro and published by Giovanni Battista de' Rossi and Nicolaus van Aelst. It is dated 1594 and we acquired it in 1963. Its medium is engraving on laid paper. It is a part of the Drawings, Prints, and Graphic Design department.

This table for the Gregorian calendar is designed for a 400-year cycle. Such perpetual calendars permit one to calculate dates far into the future. The Gregorian calendar was introduced in 1582 and was heavily promoted by the Catholic Church. The design is dedicated to Cardinal Pietro Aldobrandini, nephew to Pope Clement VIII and important patron of the arts. The engravers, whose names are prominently displayed, may have dedicated this print in hope of future patronage.

It is credited Museum purchase through gift of E.F. Caldwell & Co..

Its dimensions are

H x W: 47.2 × 39.5 cm (18 9/16 × 15 9/16 in.)
