A lovely exhibition at the Frick showcases the drawings of Andrea del Sarto, the Florentine sixteenth century artist.  The show highlights the creative process and the role of drawing in the Renaissance workshop.  The drawings on view at the Frick span del Sarto’s career.  They are amazingly nuanced and mostly in red and black chalk.  Possibly the most striking drawings are the various head studies, amongst which are the Study for the Head of Julius Caesar – most elegant – and the expressive Study for the Head of Saint John the Baptist.  Also in the exhibition are three finished paintings, including a masterful (the draping of the sleeve – wow!) Portrait of a Young Man and an innocent yet sensuous Saint John the Baptist from Palazzo Pitti.
