LOVE just came out of the dark. Or so it seems at the Frick Collection, which just reopened its refurbished Fragonard Room. Now, thanks to the miracle of fiber-optic lighting, these sumptuous paintings of chubby cupids and lissome lasses – commissioned more than two centuries ago by Louis XV’s mistress Madame du Barry – look freshly painted, even on the dreariest day.

New to the room is a 2-foot-tall statue of a lithe Diana the Huntress, and a spectacular clock – Clodion’s “The Dance of Time,” a clear glass globe supported by three nymphs.

This week, the Frick also unveiled its Gabriel de Saint-Aubin retrospective, mounted in league with the Louvre. In case you’ve wondered what Paris was like 250 years ago, France’s master draftsman can draw you a picture (or 50) of the French Enlightenment.

Pick up one of the magnifying glasses in the hallway, the better to see cunning little details – like the chorus line of aspiring nude male models that line up in Saint- Aubin’s “Four Sketches at the Academe de Saint-Luc.”

Look closely and you’ll see that one of the men in the drawing – also armed with a magnifying glass – is examining the models’ umm, assets.
