From September 1513 to 1516, under Pope Leo X, Leonardo spent much of his time living in the Belvedere in the Vatican in Rome, where Raphael and Michelangelo were both active.  In October 1515, King Francis I of France recaptured Milan. On 19 December, Leonardo was present at the meeting of Francis I and Pope Leo X, which took place in Bologna.  Leonardo was commissioned to make for Francis a mechanical lion that could walk forward then open its chest to reveal a cluster of lilies. [k] In 1516, he entered Francis' service, being given the use of the manor house Clos Lucé, near the king's residence at the royal Château d'Amboise. He spent the last three years of his life here, accompanied by his friend and apprentice, Count Francesco Melzi, and supported by a pension totalling 10,000 scudi.  At some point, Melzi drew a portrait of Leonardo; the only others known from his lifetime were a sketch by an unknown assistant on the back of one of Leonardo's studies (c. 1517) and a drawing by Giovanni Ambrogio Figino depicting an elderly Leonardo with his right arm assuaged by cloth. [l][m] The latter confirms an account of Leonardo's right hand being paralytic at the age of 65, which may indicate why he left works such as the Mona Lisa unfinished.  He continued to work at some capacity until eventually becoming ill and bedridden for several months, as Vasari states.
