 Over the five years following he produced a large body of work; each piece was signed in various manners, and was dated and marked as a product of Urbino.Such consistency in signing his work was unusual at the time; there is some suggestion that the artist was blacklisted after the labor troubles of 1530, and that his choice to sign his works might be in some way related to his difficulties.After 1535, Xanto seems to have become less prolific; his works, if signed, are marked in more cursory fashion.
