NICHOLAS KRATZER POLYHEDRAL SUN DIAL  1525

NICHOLAS KRATZER  :  1487 - 1550 ( ? )  :  

Diallist, Clockmaker, Mathematician & Astronomer to Henry V111

This is not intended to be a strict copy of Kratzer's Dial, which is in The Museum of Science, Oxford. It is however approximately the same size & retains the character of the original, It well illustrates the principle that a sundial can be designed to face in any direction.
