|First Appearance||"Child's Play"|
The Circumscope is a version of what we, today, would recognize as a periscope. The first periscope-type device was designed by Johannes Gutenberg in the 1430s but the device we are familiar with wasn't perfected until World War I.
Appearances and Mentions
- Murdoch and Crabtree were able to use the Circumscope to view children bringing stolen horses to the Rookwood & Watt Glue Factory and Tannery.
- Murdoch builds an elongated circumscope out of the water closet “tubes” and Julia's mirrors to view the room above theirs at the Park Embassy hotel, first through the windows then through the heater vent.
