Mural Quadrant


mural quadrant Early instrument used for measuring declination. It consists of a graduated circle fixed to a wall (in Latin, murus) orientated north-south. A telescope (or, in early versions, a simple sighting tube) is mounted centrally on a pivot so that its position can be read off the circle. The eyepiece of the telescope contains a horizontal graticule along which the image of the star must move as the Earth turns. Setting of the telescope must be done quickly, as the star passes the meridian. It was superseded in the mid-19th century by the transit circle.
