Or linear, developed in Italy in the 15th century, a mathematical system is used based on orthogonals receding to vanishing points on the horizon; transversals intersect the orthogonals at right angles at distances derived mathematically; since this presupposes an absolutely stationary viewer and imposes rigid restrictions on the artist; it is seldom applied with complete consistency; although traditionally ascribed to Brunelleschi, the first theoretical text on perspective was Leon Battista Alberti’s On Painting (1435).


Literally “a place for writing”, is commonly used to refer to a room in medieval European monasteries devoted to the writing, copying and illuminating of manuscripts by monastic scribes.
