In 1516, Leonardo entered Francis' service, being given the use of the manor house Clos Lucé, near the king's residence at the royal Château d'Amboise. Being frequently visited by Francis, he drew plans for an immense castle town the king intended to erect at Romorantin, and made a mechanical lion, which during a pageant walked toward the king and—upon being struck by a wand—opened its chest to reveal a cluster of lilies. Leonardo was accompanied during this time by his friend and apprentice, 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. The latter, in addition to the record of an October 1517 visit by Louis d'Aragon, 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.
