It has been observed that the golden ratio is evident in the arrangement of branches along the stems of plants, and of veins in leaves. The golden ratio also has a place in art when used to determine what arrangements of a composition  are aesthetically pleasing to the eye. Some would suggest that the "perfect" human face adheres to the golden ratio <ref> http://www.beautyanalysis.com/index2_mba.htm </ref>.

[[Leonardo da Vinci]] was a close friend of Luca Pacioli, who published a treatise (''Divina Proportione'') on the Golden Ratio in 1509. It has been claimed that he used the Golden Ratio in his composition of the [[Mona Lisa]], but there is no documentation to prove this.
