Annotation:[Canterbury Catalog: Cylinder made of "isinglass", recognised by Bargrave to have come from the workshops in "High Germany". Isinglass is a type of Muscovite cylinder (also known as Common mica or Potash mica). Bargrave writes: "there are several uses of them in opticks. I used them with some several pictures, which are artificially painted like the greatest confusion ... a cylinder being placed upon the square ... all the reflections of that seemingly confused work meet in the cylinder, and make a very handsome picture".] (missing) (approx early - mid 17th cent)
