It is generally belived to have begun in Florence, Italy, in the Late Middle Ages and later spred across the rest of Europe. In part it was a consequence of a renewed intrest by the scolars of the time in aincient Latin and Greek litterature and history, where before they had focused principally on works of natural science, philosophy and mathematics.
Below are some key works from the Renaissance Period made by two of it's key artists Leonardo da Vinci and :

Giotto di Bondone, 1310, Tempera on wood
Leonardo da Vinci, 1505, Oil on wood
One way to begin to understand the significance of the Renaissance is to look at the similarities and differences between these two images. Starting with the similarities, both are of a religious subject, the Virgin mother and child. In each these figures provide the principal focal point, with the other imagery framing them or comprising the background. It is here that we begin to notice some obvious differences between the images. In the first image the background and the figures in the foreground are both pushed up towards what is known as the picture plane, or the surface of the picture. There is a suggestion of depth, but it feels relatively forced and inaccurate. Likewise, the modeling on the figures feels a bit flat and awkward as though the artist is trying to suggest three dimentions but doesn't quite know how to do it. By comparison the second image is much more successfully three dimentionally modeled. As can be seen from the detail above, the figures have a much more successful sense of form, which no longer feels forced or awkward, even where the drawing is still in parts somewhat inaccurate. Although the background to the image still looks somewhat flat, as though it were a theatrical backdrop, it is rendered with far greater detail and the suggestion of depth is much more effective.
