This is a small study (approx. 6X8 inches) on vellum with gesso and magic marker. last night I began blocking out a much larger version (approx. 6 X 4 feet) on untreated wood. Whereas in this study the negative space is white, the plan is to leave the wood grain exposed in the larger version.
I originally approached this scene because of the deteriorating tile wall, but as I came to the protective fence I saw in the foreground the roman foundation which was part of the amphitheatre across the street. Double the pleasure.
