Quadrant (Accepted)

A quadrant is a period astronomical instrument used for measuring elevation from the horizon.  It consists of a graduated quarter-circle (hence the name) with a movable index and a sight; an example with heraldic interest is a horary quadrant engraved with the badge of Richard II, 1399 [Marks & Payne 35].  For related charges, see astrolabe, sphere, sundial.
