This perpetual calendar from 1855 is a fascinating piece of printing history and timekeeping. Designed by J.C.V. and printed by Charvin and Nigon in Lyon, this document illustrates the complexity and ingenuity of date calculation systems in the 19th century.
Made on paper, this calendar features multiple tables for determining dominical letters, the golden ratio, epacts, and movable feast days according to the Julian and Gregorian calendars. It incorporates an ingenious rotating mechanism, secured by a brass clasp, which allows the various variables to be aligned. A detailed illustration of an angel holding an hourglass and a scythe adds an allegorical dimension to the piece. This historical item measures 66 cm high by 46 cm wide.
Its overall condition reflects its age and past use, retaining all its period character. The paper has a natural patina that testifies to its authenticity.
This historical document would look perfectly at home framed in a classic study, library, or cabinet of curiosities. It integrates ideally into classical or eclectic interiors, adding a touch of erudition and mystery.
See photos, thank you.
