This is a great piece, a Victorian kaleidoscope.It is cylindrical in shape tapering up to the eye piece.The wooden casing is mahogany.

It measures 22cm h x 8cm w at the base.

It works by shaking the piece and different patterns appear.

 The kaleidoscope was invented in 1816 by a Scottish scientist called Sir David Brewster. He patented his invention in 1817 and named it 'kaleidoscope' after three Greek words: 'kalos', meaning 'beautiful', 'eidos', meaning 'form' and 'scopos', meaning watcher.
