Hermes was a key member of the early twentieth-century wood engraving revival and one of the founders of the English Wood Engraving Society in 1925. Wood engraving was at the time considered a feminine craft, with little physical strength required, and was not highly regarded by art critics. This print evolved from a maquette (a scale model) for a sculpture which was named 'Triangular Form'. It is interesting that the print is black monochrome because from the 1940s on Hermes mainly worked in colour: her job as a draughtsperson in aircraft production and shipbuilding in the 1940s having made her 'heartily sick of black and white'.
