Cosimo III was succeeded by his son, Gian Gastone, who, for most of his life, kept to his bed and acted in an unregal manner, rarely appearing to his subjects, to the extent that, at times, he had been thought dead.
Cosimo III järglane oli tema poeg Gian Gastone, kes enamuse oma elust hoidus voodisse ja tegutses valitsejale mittekohasel viisil, ilmudes sel määral harva oma alamate ette, et mõnikord peeti teda surnuks.
