Diptychs or Sundials for the pocket or purse

Quadrants with a compass, introduced in the 15th century, were the first
portable sundials. The compass served to face the quadrant toward the
north and the gnomon (a bit of cord or a flexible triangle) could be
raised or lowered to accommodate the latitude where the compass is used.
The golden age of sundials lasted from the 15th century to the end of
the 18th.
