Description: | This is a horary quadrant marked with Gunter scales. The reverse shows a perpetual calendar for the years 1676 to 1703, a very unusual addition to this type of instrument. It is signed 'Ann Shepard fecit in Bristoll 1676'. She may have been the maker but most likely was the seller. Unusually it is made of ivory, and would have been an expensive instrument to buy. No other instruments signed by Shepard are known.
Fitted with plumb bob and 1 sight hole missing.
Table of epacts and Dominical letters for the years 1676 to 1703.
