I love the almost optical illusion of this kind of knot: looking at either the light or dark ink paths, at a glance, it appears as if there are two offset triangular figures. Tracing that path quickly reveals that something much weirder is going on. The same basic knot is doubled, with its copy being rotated in place.

At the time I drew this, my mind was preoccupied with the sculptures of Wenzel Jamnitzer (or at least Jost Amman’s woodcuts of them, assuming the sculptures ever existed).
