“When I unbutton the sleeve of a shirt/Shades of sky under my skin awaken,” read the opening lines of Maria Barnas’ poem You and I, used at the start of Viviane Sassen’s new photobook, Roxane II. Abstract though these lines seem, they possess a subtle symmetry with the images which follow, in which expanses of pale skin sit in stark juxtaposition to graphic, almost blindingly bright streaks of colour. In Roxane II, the human and the organic seem to bleed into one another with captivating results.
