Galileo Galilei was portrayed by some of the most famous painters of his time, such as Santi di Tito, Caravaggio, Francesco Villamena, Domenico Tintoretto, Ottavio Leoni, Domenico Passignano, Joachim von Sandrart, and Claude Mellan. However, the most famous portraits, now in the Palatine Gallery and Uffizi Gallery in Florence, were painted by Justus Susterman. The painting in the Uffizi shows Galileo as an old man, following a model associated since antiquity with the figure of the "philosopher," the savant able to reveal the secrets of Nature. This theme was celebrated in the funerary monument built in Santa Croce in 1737. It also informs many nineteenth-century representations, in particular in the Tribuna, built by Grand Duke Leopold II, and in the paintings showing the highlights of Galileo's life: the scientific discoveries, the abjuration, the presumed meeting with Milton in Arcetri, and the Apotheosis.
