Hi,
Admittedly, it's not being used as a lacemakers lamp, but I've seen
pictures of Robert Hooke's microscope set-up with the same idea of a
candle and a bowl of water to focus the light in lectures. His major
publication on microscopy was in 1665 and, as far as I can tell, the
picture here is from the same time
http://www.omni-optical.com/micro/sm101.htm I've tried looking
through my Optics handouts, but it must have been a separate slide
that the lecturer only put up for a few seconds.

hello,
can somebody tell me from what time a lacemakers lamp (in Dutch : ordinaal),
has been used ? Are there old paintings (16th or 17th century) with lacemakers
using an "ordinaal " ?????
