Regardless as to the veracity of Vasari's account, it is certainly true that Pontormo's artistic idiosyncrasies produced a style that few were able (or willing) to imitate, with the exception of his closest pupil Bronzino. Bronzino's early work is so close to that of his teacher, that the authorship of several paintings from the 1520s and '30s is still under dispute—for example, the four "tondi" containing the Evangelists in the Capponi Chapel, and the "Portrait of a Lady in Red" now in Frankfurt.
