Summary

Description
English: This is a drawing of a centrolinead, a type of technical drawing instrument used for drawing lines in perspective, particularly when their w:Vanishing point lies outside the drawing board.

This particular design is attributed to John Farey in Instrument for making perspective drawings, 1814, though the author William Stanley attributes it instead to Peter Nicholson, who is also associated with another sort of centrolinead. When the instrument rests against two pins as shown, lines drawn along its long edge have a common vanishing point that lies at a distance along the dotted line.

Alongside the centrolinead is a detailed drawing of a house in two-point perspective, with the drawing edge of the instrument aligned with a fence to show that it was draw using the instrument.
