A superb perpetual calendar made by ‘Hemisferium’ who specialise in creating extraordinary replica scientific instruments lost to history. Their goal is to recreate objects that link us to our scientific past and therefore make them accessible to all those who love the art and beauty of science.
This piece is a perpetual calendar made from solid brass with a dial on each side and a dark wood stand which makes it an unusual display piece. I understand that this calendar starts at 1 January 1600 and ends at 31 December 2799.
Sadly, the original box and instructions have been lost, but the calendar will be sent in a good quality box suitable if you want to present it as a gift.
The calendar is in excellent condition, the dial on the front is a little loose compared to the dial on the back, but I think that may be part of the design. The little hardwood stand is also in excellent condition.
The calendar measures 9cm in diameter and, the depth, including the dials on each side, is approx. 1.5cm. It is very heavy for its size, 327g, which goes to show the amazing quality of this interesting reproduction.
A very unusual display piece perfect for anyone interested in scientific instruments of the past.
