What We Know
The stairs up to the studio were almost always in a shadowed space, but in the spring of the year, for only a few weeks at most, a lozenge of light, or some days a tentacle, or a band, or fan, or spray, depending on the cloud cover or angle, slides down the wall and describes a new space in what is a familiar but often overlooked passage.
It points out how we can still be surprised by what we think we know.
