Giotto
Ernesto Scrovegni belonged to a banking family in Padua whose patriarch, Reginaldo degli Scrovegni had a bad reputation. He commissioned the building of a chapel in Padua and its fresco decoration by Giotto.
Michelangelo took approximately four years to paint the Sistine Chapel's ceiling, from 1508 to 1512. The frescoes, which cover about 12,000 square feet, depict various biblical scenes, including the iconic "Creation of Adam." The project was commissioned by Pope Julius II and remains one of the most significant masterpieces of Renaissance art.
