City-state of bankers and patrons
Florence was a rich city-state thanks to banking and trade in wool and cloth. The most powerful family was the Medici, bankers who used their wealth to become patrons: they paid artists, architects, and scholars to create new works.
Italian city-states like Florence, Venice, and Genoa grew rich because they sat on trade routes between Europe, the Middle East, and Asia, partly thanks to trade that expanded after the Crusades.
Sketches, art, and science
Leonardo da Vinci (1452–1519) painted the Mona Lisa and The Last Supper. He also filled notebooks with sketches of flying machines, human anatomy, and engineering ideas, written in mirror-image handwriting.
Leonardo is often called a "Renaissance man": a person skilled in many fields, from art to science.
Renaissance artists used perspective, a technique that makes flat paintings look three-dimensional, and studied real human bodies to paint them realistically.
David and the Sistine Chapel
Michelangelo (1475–1564) carved the marble statue David (finished in 1504), which stands more than 5 meters (17 feet) tall. From 1508 to 1512, he painted the ceiling of the Sistine Chapel in Rome, lying on scaffolding for four years.
His work reflects humanism, a Renaissance idea that celebrated human potential and achievement, and that encouraged the study of classical (Greek and Roman) texts.
Gutenberg's workshop, about 1450
Around 1450, Johannes Gutenberg in Germany developed a printing press with movable metal type. Before this, books were copied by hand, which could take months.
Soon, printers could make hundreds of copies quickly and cheaply. By 1500, millions of books had been printed in Europe. More people learned to read, and new ideas spread faster than ever before.
A church door in Wittenberg, 1517
In 1517, a German monk named Martin Luther wrote the Ninety-Five Theses, criticizing the Catholic Church, especially the sale of indulgences (payments that people were told would reduce punishment for sins).
Thanks to the printing press, copies spread across Germany in weeks. Luther's ideas led to the Protestant Reformation and the creation of new Christian churches. Europe was divided between Catholic and Protestant regions, which led to many conflicts.
