Cosimo II de' Medici

Cosimo II de' Medici (12 May 1590 – 28 February 1621) was Grand Duke of Tuscany from 1609 until his death. He was the elder son of Ferdinando I de' Medici, Grand Duke of Tuscany, and Christina of Lorraine.

For the majority of his 12-year reign, he delegated the administration of Tuscany to his ministers. He is best remembered as the patron of Galileo Galilei, his childhood tutor.

Biography

Cosimo's father Ferdinando I took care to provide him with a modern education. Indeed, Galileo Galilei was Cosimo's tutor between 1605 and 1608. Ferdinando arranged for him to marry Archduchess Maria Maddalena of Austria, daughter of Archduke Charles II, in 1608. Their marriage was celebrated with an elaborate display on the Arno, which included a performance of the Argonautica, in which Jason sailed around an artificial island and presented Maria Maddalena with six red apples, alluding to the Medici family symbolic balls, or palle. Cosimo and Maria Maddalena had eight children in just eight years; among them was Cosimo's eventual successor, Ferdinando II, an Archduchess of Inner Austria, a Duchess of Parma and two cardinals.

Ferdinando I died in 1609. Due to his precarious health, Cosimo did not actively participate in governing his realm, but he was a great patron of science and letters. Just over a year after Cosimo's accession, Galileo dedicated his Sidereus Nuncius, an account of his telescopic discoveries, to the grand duke.

Cosimo extended the Palazzo Pitti, and he reconstructed the Villa del Poggio Imperiale. The already famous Galileo had used his telescopic accomplishments in his bid for patronage. Once appointed, Galileo moved to the Florence court and found a resource rich environment where he worked as philosopher, mathematician and astronomer. Galileo was actively involved in court life and supported the dynastic rhetoric of the Medici family. Aside from producing intellectual spectacles, Galileo used the Medici court to advance his theoretical claims and discoveries. The four moons of Jupiter he had discovered were named Medicean Stars in reference to Cosimo and his three brothers. Tuscan ambassadors were used to advance scientific debate in Europe. Ambassadors in Prague, Paris, London and Madrid received copies of Galileo's Sidereus Nuncius and were sent telescopes constructed by Galileo, paid for by the court treasury.
