"an essay on Vermeer of Delft"
Vermeer's View of Delft
In 1902 Proust went to Belgium and Holland, seeing Vermeer's View of Delft,
which had a profound impact on him. Johannes Vermeer (1632-1675) was a Dutch Baroque painter, now particularly known for his painting Girl With a Pearl Earring.
Proust writes about the View of Delft
later in the Search,
in volume V, The Captive.
