Archimedes' Shield

Attributes
Archimedes' Shield is a round shield, approximately 1m in diameter, dated to around 250 BCE. It is backed with leather, but its front is a reflective metal of unknown composition (analysis has proved impossible).

When its surface is uncovered, a beam of white light is emitted from the centre. This occurs regardless of whether there is any other light source. The beam is powerful enough to blind those using it and burn through wood or plaster. Protracted usage can melt metal.
