The Golden Rectangle: Here is a brief history of what the golden rectangle is and how it came to be.
This "golden rectangle began as a golden ration of 1.618 to 1. Apparently the discovery of the golden ratio traces all the way back to Plato who supposedly worked with this ratio many times in ancient Greece. The ration was then rediscovered in 370 B.C. by a man named Eudoxus. The first to actually mention this ration to the public though was Proclus around 450 A.D. Since in ancient times the "golden Ratio" was represented in segments instead of just numbers the ratio was then used to create a "golden rectangle". The ration of length to width is what makes the rectangle distinct.
