1267-1337. Italian painter and architect. He broke away from the conventional Gothic style of the time, and introduced a naturalistic style, painting saints as real people. He painted cycles of frescoes in churches at Assisi, Florence, and Padua. He is said to have designed the campanile (bell tower) in Florence. Giotto was born in Vespignano, N of Florence. The interior of the Arena Arena Chapel, Padua, was covered by him in a fresco cycle (completed by 1306) illustrating the life of Mary and the life of Jesus. Giotto's figures occupy a definite pictorial space, and there is an unusual emotional intensity and dignity in the presentation of the story. In one of the frescoes he made the Star of Bethlehem appear as a comet; Halley's comet had appeared 1303, just two years before. From 1334 he was official architect to Florence and from 1335 overseer of works at the cathedral; he collaborated with Andrea Pisano in decorating the cathedral facade with statues and designing the campanile, which was completed after his death.
