The Birth of the Virgin
XVI century.Not on display
This seems a good drawing by a competent hand. While there are some hints of the work of the two sienese artist, Andrea Casolani (1522/23-1608) and Astolfo Petrazzi (1579-1665), other aspects of the drawing´s style point to that of Roman artists from the circle of Cherubino Alberti (1553-1615).
