Erratic Boundaries is a collection of ten pen and ink drawings by architect and artist Sigrid Miller Pollin, coupled with ten ekphrastic poems by poet and economist Jane D'Arista. The drawings pull the viewer into fanciful natural and constructed visual moments, and invites the reader into an osmotic ricochet from poem to drawing. The book title is embedded in Poem IV. Here, sky rises like a canopy above erratic boundaries where land and water meet- boundaries so elemental we borrow their irregular connections to name the ragged edges of human life: birth, death, youth, age and what we call love and loss.
