Don't we all have a certain number of images that stay around in our head, which we undoubtedly call memories and improperly so, and which we can never get rid of because they return in our sky with the regularity of a comet - torn away also from a world about which we know almost nothing? They return more frequently than comets do, in fact. It would be better, then, to speak of them as loyal satellites, a bit capricious and therefore even troublesome: they appear, disappear, suddenly come back to badger our memory at night when we cannot sleep. But, little as we may care to, as our hearts tell us to, we can also observe them at will, coldly, scrutinize their shadows, colors, and relief. Only, they are dead stars: from them we shall never grasp anything other than the certainty that we have already seen them, examined them, questioned them without really understanding the laws that the line of their mysterious orbits obeyed.
