Thinkers Timeline

Leonardo da Vinci was an Italian artist, scientist, and inventor. He was born in 1452 in the small town of Vinci, near Florence, in what is now Italy. His name means 'Leonardo from Vinci'. He was the son of a young woman named Caterina, who was probably a peasant or servant, and a wealthy notary named Ser Piero. His parents never married. Leonardo grew up in his father's family but was treated as a separate, somewhat outside figure. He showed great talent young. As a teenager he was apprenticed to the artist Andrea del Verrocchio in Florence. He learned painting, sculpture, and many practical crafts. Around the age of 30, he moved to Milan to work for the Duke, Ludovico Sforza. He stayed in Milan for nearly 20 years. He painted, designed weapons, planned buildings, and filled notebooks with ideas. When French armies invaded Milan, Leonardo moved on. He worked in Florence, Rome, and other Italian cities. He served various rulers, including Cesare Borgia and the Medici. In 1516, the king of France, Francis I, invited him to come and live in France. Leonardo accepted. He spent his last three years in a small castle near the king's palace at Amboise. He died there in 1519, aged 67. He never married and had no children. He was probably gay, though the evidence is indirect. He was vegetarian, unusual for his time. He left thousands of notebook pages full of drawings and ideas, most of which were not read for centuries.

Niccolò Machiavelli was an Italian writer, diplomat, and political thinker. He was born in 1469 in Florence, then a powerful Italian city-state. His family was middle-ranking and not rich, but his father had a good library. Machiavelli was educated in Latin, history, and the classical writers of ancient Rome. In 1498, at the age of 29, he became a senior official of the Florentine Republic. For the next fourteen years he served as a diplomat and adviser. He travelled across Italy and Europe on missions, meeting popes, kings, and warlords. He watched up close how power actually worked. He saw cruelty, betrayal, and luck shaping politics far more than virtue or law. In 1512 the Republic fell. The Medici family, who had ruled Florence before, returned to power. Machiavelli lost his job. He was suspected of plotting against the Medici, arrested, and tortured. Released and sent into rural exile, he spent his days farming and his evenings writing. In 1513 he wrote The Prince, a short, sharp book of advice for rulers. He hoped it would win him a job back in Florence. It did not. He also wrote a longer work, the Discourses on Livy, a study of Roman republican history, plus comedies, histories, and military essays. He died in 1527, just before the Republic briefly returned. The Prince was published five years after his death. It became one of the most controversial and influential books in the history of political thought.
