Afilmywap’s night at the museum became a kind of rumor there. The janitor swore he heard laughter coming from the Greco-Roman wing at dawn; the conservator found a painted-over line on a canvas that now revealed a hidden smile; a child visiting with a class declared she had seen the pictures wink. The official records were, predictably, mute. But artifacts have a way of keeping gossip, and museums are, in their core, institutions of testimony. The books would catalog the accession numbers; the stairwells would keep the footnotes. The notebooks, however, preserved the margins.
