Encounter of an umbreall

In the couturier's studio, the famous "encounter of an umbrella and a sewing machine on a dissecting table" evoked by Lautréamont in Maldoror reveals itself to be a perfectly ordinary occurrence, a phenomenon totally integrated into creative process. Isn't the couturier -medium, conjurer and high priest of the transubstantiation of trends into symbols of the time - also entitled to declare, as Mirô did in front of one of his canvas, "This is the color of my dreams"?

can you help me make clear the paragrap. first, I cant find out what is evoked by Lautreamont. is it the clause in the nail and I am confused about "the famous". I dont know where I have to relati it.
in short what the paragraph tell us.
