Isaac Newton invented the reflecting quadrant around 1699 and he gave a detailed description to Edmond Halley, but this was not published until after Halley’s death in 1742.  Octants, quadrants and sextants are closely related and measure the angle between objects.  They can be used vertically, such as to find the angle between the horizon and the sun, which determines latitude or they can be used horizontally to determine distance from the shore.
