Who drew the perfect circle?

The artist Giotto di Bondone is known for drawing the perfect circle. Although it may only be a legend, the story goes that the Pope sent a messenger to Giotto requesting that he prove his drawing ability. In one stroke, Giotto drew a perfect red circle.

Giotto was primarily self taught. He was known for using brush strokes that were tighter than normal and allowed for more realism in his paintings. Giotto was born in Florence, Italy, in 1266 and he died in 1377. Giotto drew many religious figures because the Catholic church was centered in Italy. Giotto's art was very well received throughout his career and remained popular after his death.
