Giotto di Bondone (c.1267–8 January 1337), usually known as Giotto, was an Italian painter and architect from Florence. He is generally thought of as the first in a line of great artists of the Italian Renaissance.

Giovanni Villani, who lived at the same time as Giotto, wrote that he was the king of painters, who drew all his figures as if they were alive. Villani says that, because he was so clever, the city of Florence gave him a salary.

In the 16th century, the biographer Giorgio Vasari says that Giotto changed painting from the Byzantine style of other artists of his day, and brought to life the great art of painting as it was made by the later Renaissance painters like Leonardo da Vinci. This was because Giotto drew his figures from life, rather than copying the style them from old well-known pictures in the way that the Byzantine artists like Cimabue and Duccio did.

Giotto's greatest work is the decoration of the Scrovegni Chapel in Padua, finished around 1305. The building is sometimes called the "Arena Chapel" because it is on the site of an Ancient Roman arena. This fresco series shows the life of the Virgin and the life of Christ. It is thought of as one of the greatest masterpieces of the Early Renaissance.

Although Vasari wrote about Giotto's life, it is not known how many of the stories are true, because Vasari was writing more than 200 years after Giotto died. Only two things are known for certain. It is known that in 1334 Giotto was chosen by the "commune" (town council) of Florence to design the bell tower next to Florence Cathedral which was being built at that time. It is also known for certain that Giotto painted the "Arena Chapel". But no-one can be certain where he was born, who his teacher was, what he looked like, whether he really painted the famous frescos at Assisi or where he was buried when he died.
