Two works hanging in Gallery Minerva’s Biltmore Avenue window are set as bait for the passersby. From afar, they are stark, black and white minimalist compositions. But up close they reveal a intricate framework of curvilinear lines, decades in the making. The works, by Connecticut artist Bryan Nash Gill, are woodcuts, nearly four feet wide. Woodcut is literal here, but in a different sense. Gill cuts out cross sections of felled trees for printing. The wood discs are lightly sanded, just enough to smooth the surface and keep the grain from shredding the paper. Each block is inked and hand-printed, resulting in abstract, organic shapes that resemble fingerprints. Smaller versions from trees of a variety of shapes and size are also available for viewing upon request.
