The Castle in the Pyrenees he has altered the laws of gravity and the behavior of matter, but space, and the landscape, continue to breathe. In Memory of a Voyage nothing has changed in the natural aspect of people and things except the materials they are made of. Because everything has become petrified, transfixed as in a monument, there is a terrible impression of all breathing having come to a stop. Here the word "souvenir," a prominent component of all works of the Romantic era, acquires an almost cynical - and, in any case, ironical - intonation.
Human memory has been swept up into the mystery of life that has been brought to a halt, but even the petrified wears away and disappears. It is not mere coincidence that during the same period Magritte also encased the living in coffins - that is, removed them from direct sight.
