Baudelaire and Rops first met through the editor Auguste Poulet-Malassis.
In a letter written to Edouard Manet, May 11 1865, the poet said:
"Rops is the one true artist - what I and perhaps I alone mean by artist - that I have found in Belgium!"
Rops for his part said:
"I was, I believe, not merely a friend, but the most faithful and respectful companion to Baudelaire, I "lightened his sadness in Belgium", as he describes it in a dedication which is very dear to me....".
The poet visited Namur and the family château of Thozée many times.
