the invention of linear perspective is generally attributed to
Filippo Brunelleschi Filippo Brunelleschi (Italian: [fiˈlippo brunelˈleski]; 1377 – April 15, 1446) was an Italian designer and a key figure in architecture, recognised to be the first modern engineer, planner and sole construction supervisor.[4] He was one of the founding fathers of the Renaissance. He is generally well known for developing a technique for linear perspective in art and for building the dome of the Florence Cathedral. Heavily dependent on mirrors and geometry, to "reinforce Christian spiritual reality", his formulation of linear perspective governed pictorial depiction of space until the late 19th century.[5][6] It also had the most profound – and quite unanticipated – influence on the rise of modern science.[6] His accomplishments also include other architectural works, sculpture, mathematics, engineering, and ship design. His principal surviving works are to be found in Florence, Italy; however his two original linear perspective panels have been lost.
Optical telescope The basic scheme is that the primary light-gathering element the objective (1) (the convex lens or concave mirror used to gather the incoming light), focuses that light from the distant object (4) to a focal plane where it forms a real image (5). This image may be recorded or viewed through an eyepiece (2), which acts like a magnifying glass. The eye (3) then sees an inverted magnified virtual image (6) of the object.
