who is often credited as the first painter to fully utilize the theory of linear perspective
Perspective (graphical) In about 1413 a contemporary of Ghiberti, Filippo Brunelleschi, demonstrated the geometrical method of perspective, used today by artists, by painting the outlines of various Florentine buildings onto a mirror. When the building's outline was continued, he noticed that all of the lines converged on the horizon line. According to Vasari, he then set up a demonstration of his painting of the Baptistery in the incomplete doorway of the Duomo. He had the viewer look through a small hole on the back of the painting, facing the Baptistery. He would then set up a mirror, facing the viewer, which reflected his painting. To the viewer, the painting of the Baptistery and the building itself were nearly indistinguishable.
Giorgio Vasari Often called "the first art historian",[7] Vasari invented the genre of the encyclopedia of artistic biographies with his Le Vite de' piÃ¹ eccellenti pittori, scultori, ed architettori (Lives of the Most Eminent Painters, Sculptors, and Architects), dedicated to Grand Duke Cosimo I de' Medici, which was first published in 1550. He was the first to use the term "Renaissance" (rinascita) in print, though an awareness of the ongoing "rebirth" in the arts had been in the air since the time of Alberti, and he was responsible for our use of the term Gothic Art, though he only used the word Goth which he associated with the "barbaric" German style. The Lives also included a novel treatise on the technical methods employed in the arts.[8] The book was partly rewritten and enlarged in 1568, with the addition of woodcut portraits of artists (some conjectural).
