A QAJAR BRASS QIBLA INDICATOR, 19TH CENTURY
A QAJAR BRASS QIBLA INDICATOR, 19TH CENTURY
The lid opening, the face engraved with astrological signs. Folding engraved string with engraved tables on underside and face.
To use the sundial one first needs to set the instrument on a flat surface and rotate it until the needle on the compass is correctly aligned in a north-south direction. When the metal pin is due north then the string is properly aligned towards the north-pole and the sundial will indicate the correct time – but only for the latitude for which it was constructed.
