Round Magic Lantern

This version has a round body to contain its lamp, and a high base.  There are ringlets hanging from both sides of the round portion, probably for decoration rather than a functional purpose.  Attaching the ringlets to pieces of rope would not suspend the lantern properly, and even if it could be suspended by rope, the metal body would quickly become hot enough to burn any such attachments.

Note the glass slide protruding from behind the lens tube.  Often, pictures were hand-drawn on these slides, although later, pictures were photographed and printed onto them.
