Unfortunately Michael Angelo was unable to execute this congenial task.

There is a magnificent portrait of this prince, as Neptune, by Sebastiano del Piombo in the private rooms of the Doria Palace at Rome.

The admiral points down with Michael Angelesque forefinger as though he were condemning his enemies to descend to the lowest depths of the sea.

It looks as if it had been inspired by a drawing of Michael Angelo's, possibly for this statue, which may have been designed as a nude figure of Neptune; the parapet in front of the picture is decorated with a painted bas-relief of a Roman galley.
Michael Angelo's last known letter to his father is supposed to have been written in June 1523.( 128) It is a bitter complaint of the testy manner in which his father always treated him, and the continual interruptions of his work.

It must have been a great grief to Michael Angelo when the old man came to die if he had not made up this quarrel with him, for he loved him in a way that is marvellous to us when we consider the character of the old man as evidenced in the correspondence.
