Winsome Pinnock's
Rockets and Blue Lights takes its title from a JMW Turner painting, but its subject revolves around a different one of the painter's seascapes, unveiled in the same year and possibly a kind of companion piece: Best-known as
The Slave Ship, it shows the aftermath of a slave ship (possibly the
Zong) jettisoning its human "cargo" in a storm. It was part of the backlash against slavery that led to abolition in British territories, and the painting and its ambiguities - is Turner's not showing the bodies of the victims letting the viewer off the hook, or forcing them to imagine horrors he can't satisfactorily put to canvas? - becomes a recurring symbol, and a starting-off point for trying to reframe the narrative: Instead of making abolition a cause for self-congratulation, looking at the legacy of slavery both at the time and down the generations.
