<P> Raphael, who moved to Florence in 1504 and to Rome in 1508, unashamedly drew on the skills of the renowned painters whose lifespans encompassed his . In his works the individual qualities of numerous different painters are drawn together . The rounded forms and luminous colours of Perugino, the lifelike portraiture of Ghirlandaio, the realism and lighting of Leonardo, and the powerful draughtsmanship of Michelangelo became unified in the paintings of Raphael . In his short life he executed a number of large altarpieces, an impressive Classical fresco of the sea nymph, Galatea, outstanding portraits with two popes and a famous writer among them, and, while Michelangelo was painting the Sistine Chapel ceiling, a series of wall frescoes in the Vatican chambers nearby, of which the School of Athens (1509 - 11) in the Stanza della Segnaturais is uniquely significant . </P> <P> This fresco depicts a meeting of all the most learned ancient Athenians, gathered in a grand classical setting around the central figure of Plato, whom Raphael has famously modelled upon Leonardo da Vinci . The brooding figure of Heraclitus who sits by a large block of stone, is a portrait of Michelangelo, and is a reference to the latter's painting of the Prophet Jeremiah in the Sistine Chapel . His own portrait is to the right, beside his teacher, Perugino . </P> <P> But the main source of Raphael's popularity was not his major works, but his small Florentine pictures of the Madonna and Christ Child . Over and over he painted, in slightly different poses, a similar plump, calm - faced blonde woman and her chubby babies the most famous probably being La Belle Jardinière ("The Madonna of the Beautiful Garden"), now in the Louvre . His larger work, the Sistine Madonna, used as a design for countless stained glass windows, has come, in the 21st century, to provide the iconic image of two small cherubs which has been reproduced on everything from paper table napkins to umbrellas . </P> <P> A leader of the Venetian School of painting, Giovanni Bellini (1430 - 1516) was born within a year of his brother Gentile, his brother - in - law Mantegna and Antonello da Messina, but lived a decade longer than the first two and almost three decades longer than the latter . He was painting right up until his death and his works illustrate several influences . His early works show the influence of Mantegna with incisive lines and clearly delineated colours while after Messina's stay in Venice in 1475 - 1476 his works adopted a Flemish - like realism and luminous colours, which shows he was highly successful at adopting the techniques of oil painting brought by Messina . He was first the teacher of Giorgione and Titian but was later influenced by Giorgione, most notably in adopting tonalism wherein paint is applied in superimposed layers creating a soft diffused effect so figures and landscapes become more unified in atmosphere . </P>
