{{Template invention |nome= Current name for the quadrant widely used in the sixteenth century by gunners. The inventor, or divulger, Nicolò Tartaglia, called it simply ''squara'' = quadrant. |inventore= Nicolò Tartaglia |data= 1537 |descrizione= Described by Nicolò Tartaglia in two versions developed respectively for aiming cannon (with a longer leg to be inserted into the gun mouth and a quarter-circle divided into 12 points with plumb bob) and to measure the height and distance of a target. In the latter case, the quadrant has legs of the same length and a shadow square with plumb bob. Mounted on one side are the sights, which can also be used, thanks to the plumb bob, to level a terrain. In measuring unknown quantities, the operation of the gunner's quadrant is similar to that of the [[quadrant]]. |componenti= |riferimentibibliografici= Tartaglia, Nicolò. ''Nova Scientia''.
