Vanishing point of multipoint perspective, and historian Kirsti Andersen compiled these observations. She notes, in terms of projective geometry, the vanishing point is the image of the point at infinity associated with , as the sightline from through the vanishing point is parallel to . As a vanishing point originates in a line, so a vanishing line originates in a plane that is not parallel to the picture . Given the eye point , and the plane parallel to and lying on , then the vanishing line of is . For example, when is the ground plane and is the horizon plane,
The Colossus (painting) crowd. The effect of the light, which possibly indicates sunset, surrounds and highlights the clouds that encircle the giant's waist as described in Arriaza's poem: This slanting light is fractured and interrupted by the mountain peaks increasing the sensation of disequilibrium and disorder. The effect is similar to Luis de Góngora's famous "dubious daylight" ("Fable of Polyphemus and Galatea" v. 72.). Instead of a centripetal composition where all the indications point towards a central nucleus, in this painting all the lines of movement shatter the unity of the image into multiple paths towards its margins. The painting can be considered
