As we all know, The Metropolitan Museum of Art is huge so this post is going to be small.
In a corner of gallery 813 was a small oil by my beloved Vilhelm Hammershoi:
is a typical interior but, as always, look closely at the brushwork.
On the windowsill are two white squares, tiny, almost imperceptible but they are there. Minuscule spots of light in between the shadows cast by the moonlight.
It is a good idea not to look up paintings beforehand, and the pleasure I gained from finding this was an added bonus to a terrific day!
