How did European paintings during the renaissance differ from those created in the years before the renissance?

Renaissance culture fostered a renewed interest in science, math, philosophy, and art. Interestingly, all of these subjects are combined in linear perspective, which uses geometric lines and a vanishing point to give the illusion of depth and space to painting. It greatly focused on realism, dimension, and depth. These method greatly differed from the middle ages which focused on religion often lacking aspects like emotion, perspective, and humans.

Explanation:

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.
