Pupil of Cimabue, Giotto is rated among the main Italian painters, he began a new style in the Italian visual art and became a model for the Renaissance artists. The fresco cycle of the Life of St. Francis for the Basilica of Assisi, the Crucifixion for the Church of Santa Maria Novella in Florence, the frescoes for the Scrovegni Chapel in Padua and those for the Basilica of Santa Croce in Florence are among his most famous masterpieces. He was also a well-known architect: he was appointed as chief architect of the Dome of Florence and he built the bell tower, which was named after him. The Republic of San Marino celebrates the 750th anniversary of his birth by a 2 Euro commemorative coin. The obverse side of the coin, designed by Luciana De Simoni, shows to the left a detail of the bell tower of the Dome of Florence and to the right a portrait of Giotto.
