THE AGE OF EXPANSION 327 heavier types of Roman architecture. But now there was a demand for grace and ventilation, and Gothic took the place of the Romanesque. Lancet-shaped windows and arches were constructed instead of the rounded windows and wide round arches on massive round pillars; tall slender spires were built in place of the massive domes and bell- capitals. St. Peter's at Rome, St. Paul's in London and St. Mark's and the Doge's Palace in Venice, may be cited as the most interesting creations of this period. In the last named, ' all influences built themselves in marble : the Greek and Oriental columns, Roman and Gothic arches, Oriental domes, Moorish ornament and colour, all combined into a new beauty neither Gothic, Classic, nor Oriental, but Vene- tian, a beauty rich in detail and daring in cosmopolitan combination.' As in architecture so in painting the Renaissance made its own contributions. The gifted Van Eyek brothers, Hubert and Jan (c. 1380-1440), began a new style in Holland; their work was fresh, bright and delightful. A kindred spirit was found in Albrecht Diirer (1471-1528) of Nuremberg and Hans Holbein (1497-1533) in Germany. But the greatest masters of all were in Italy. They were Leonardo da Vinci (1452-1519) who painted his masterpiece (Last Supper) on the wall of a convent in Milan ; Raphael (1483-1520), 'the best beloved of artists', whose Madon- nas are counted among the world's treasures; Michael Angdo (1475-1564) with his wonderful frescoes (e. g. the Last Judgment in the Sistine Chapel at Rome) ; and Titian (1477-1576), the Venetian master, 'celebrated for his por- traits which have preserved for us in the flesh and blood, so to speak, many of the most noteworthy personages of his time.' The change in artistic traditions brought about by all these Renaissance artists is well summed up by
