Horizon science of graphical perspective. Assuming the picture plane stands vertical to ground, and "P" is the perpendicular projection of the eye point "O" on the picture plane, the horizon is defined as the horizontal line through "P". The point "P" is the vanishing point of lines perpendicular to the picture. If "S" is another point on the horizon, then it is the vanishing point for all lines parallel to "OS". But Brook Taylor (1719) indicated that the horizon plane determined by "O" and the horizon was like any other plane: The peculiar geometry of perspective where parallel lines converge in
The Mysteries of the Horizon The Mysteries of the Horizon The Mysteries of the Horizon () is a 1955 Surrealist oil painting by René Magritte. The painting depicts three seemingly identical men in bowler hats. They are in an outdoor setting at twilight. Though they appear to be sharing the same space each one also seems to exist in a separate reality. Each is facing a different direction. In the sky above each figure is a separate waxing crescent moon. Men in bowler hats appear frequently in Magritte's work starting with his 1926 painting "The Musings of a Solitary Walker".
