an ingenious painter, sculptor, and architect of Florence, born in 1276. He was the disciple of Cimabue; but far superior to his master in the air of his heads, the attitude of his figures, and in the tone of his colouring; but could not express liveliness in the eyes, tenderness in the flesh, or strength in the muscles of his naked figures. He was principally admired for his works in mosaic; the best of which is over the grand entrance of St Peter's church at Rome. The observation of Alberti on that piece is, that in the ship of Giotto, the expression of fright and amazement of the disciples at seeing St Peter walk upon the water is so excellent, that each of them exhibits some characteristic sign of his terror. His death happened in 1336, and the city of Florence honoured his memory with a statue of marble over his tomb.
