On the 9th of November 1520 he writes that his gossip, Giovanni da Reggio, "goes about saying that you did not execute the figure, but that it is the work of Pietro Urbano.

Take good care that it should be seen to be from your hand, so that poltroons and babblers may burst." On the 6th of September 1521 he returns to the subject.

Urbano was at this time resident in Rome, and behaving himself so badly, in Sebastiano's opinion, that he feels bound to make a severe report.

"In the first place, you sent him to Rome with the statue to finish and erect it.
What he did and left undone you know already.

But I must inform you that he has spoiled the marble wherever he touched it.
