Luke and Mark stand side by side on this cover panel from the Codex Washingtonianus (compare with photo of page from Codex Washingtonianus), housed in the Smithsonian’s Freer Gallery, in Washington, D.C. The encaustic (painted in wax on wood) portraits date to the seventh century—two hundred years later than the text they protect.
