Lil Neilson has strong parallels with Joan Eardley (1921–1963), quite apart from their association, friendship, and lives in Catterline in Northeast Scotland. Sunrise Over a Seawall, Catterline and A Beached Boat speak to both the similarities in their work and the divergence. Looking at the same subjects, in particular the dark winters of dramatic sea and storm cloud, she was drawn to this wild, beautiful, forbidding place and exacted her painterly vision. Sunrise Over a Seawall, Catterline belongs to 1963 where the artist takes an imaginative, abstract approach to the subject. There is no sea wall structure in Catterline Bay: is it the sea this is the wall? Is it the harbour wall which shelters an enigmatic structure? It is a powerfully realised work that chimes with other directions in Scottish painting. Neilson was a restless searcher for well-being and truth and remains an enigmatic figure who is still to be fully appreciated as a great Scottish painter.
