Hemisferium - Paper Octagonal H05

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.
