Apparently death masks were all the rage in the past…especially for highly important people like Isaac Newton. The one that I saw last week was taken as a guide for the artist who had been commissioned to make Newton’s tomb in Westminster Abbey. This wasn’t the only Newton goodie (if you can call it that!) on display when I was taken on a tour of the Royal Society’s Library and Archive last week. There was also a lock of his hair, the original manuscript of Principia, a diary detailing the first recorded version of the famous apple story and even a piece of bark from that fateful apple tree.
