This new exhibition at The Frick Collection, through December 1, 2002, provides an opportunity to see an array of drawings by 17th century masters. It is the type of show that begs careful study. Viewers, of course, will find their own favorites.Among the especially impressive, for example, is Nicolas Poussin's "Salome Receiving the Head of Saint John the Baptist." Another is Jean-Baptiste de Champaigne's "Nude Study of a Standing Man, with Light Drapery." Another one that I found especially impressive was Nicholas de Plattemontagne's "Three Studies of a Head" in black, red and white chalk on beige paper. There are more than 30 artists represented in the exhibit, and the intimate surroundings of the attractive Frick make it possible to pay close attention to the delicate work and appreciate the contributions that come from the period under inspection.
