The iconography derives from late Mannerist prototypes; see, for example, Giovan Vincenzo Forli's Madonna del Suffragio, in the church of S. Maria della Sapienza, Naples.

For the attribution compare five small coppers in the Museo di Capodimonte, Naples (see, for instance, R. Lattuada, Opere di Francesco Guarino a Campobasso, Prospettiva, Oct. 1982, p. 64, note 27).

Professor Riccardo Lattuada will publish this picture in his forthcoming catalogue raisonné of the artist's work
