Anamorphosis Ref: LH-A407
The distorted forms or anamorphosis was a very popular instrument during the XIX century. It consists of hidden figures appearing when projected on a reflecting surface, as a cylinder, cone or pyramid.
Although the terminology "anamorphosis" was first used in the XVII century, Leonardo Da Vinci described it on his notes.
Manierism (Europe 1530-1600) was totally characterised by distorted forms. Painters showed special interest in objects distorted by convex mirrors. In this art context, the anamorphosis took place and as a clear example, please refer "The Embassadors" (detail on the sword) by Hans Holbein.
Curious tip: You can download a programme from the Internet (www.anamorphosis.com) that allows you see the anamorphosis in your own images.

Perpetual Calender Ref: LH-H27
Only perpetual calendars meet the basic condition of permitting the deduction of any essential data from any other data (year, month, week and day). However, all the analogue perpetual calendars known are hardly perpetual since the limit of their calculations is about 50 years.
Our calendar starts at January 1, 1600, and ends at December 31, 2799. It is based on a repeating cycle of 400 years and a solar cycle of 28 years. It works by means of the "Dominical letter".
