Picture after picture he painted thus upon that dark background; ships first and foremost, ships at anchor, ships flying before the storm, ships in harbour; he painted sunsets and dawns; he painted the night; he painted the sea in every aspect; he painted the gaudy brilliancy of Eastern ports, and men and women, their houses and their attitudes. He was an accurate and unflinching observer, schooled to that "absolute loyalty towards his feelings and sensations", which, Conrad wrote, "an author should keep hold of in his most exalted moments of creation". And very quietly and compassionately Marlow sometimes lets fall a few words of epitaph which remind us, with all that beauty and brilliancy before our eyes, of the darkness of the background.
