'She's a genius, I believe, because she lights up every subject she touches.' Hilary Mantel A Spectator Book of the YearGoethe claimed to know what light was. Galileo and Einstein both confessed they didn't. On the essential nature of light, and how it operates, the scientific jury is still out. There is still time, therefore, to listen to painters and poets on the subject. They, after all, spend their lives pursuing light and trying to tie it down.Six Facets of Light is a series of meditations on this most elusive and alluring feature of human life. Set mostly on the Downs and coastline of East Sussex, the most luminous part of England, it interweaves a walker's experiences of light in Nature with the observations, jottings and thoughts of a dozen writers and painters - and some scientists - who have wrestled to define and understand light. From Hopkins to Turner, Coleridge to Whitman, Fra Angelico to Newton, Ravilious to Dante, the mystery of light is teased out and pondered on. Some of the results are surprising.By using mostly notebooks and sketchbooks, this book becomes a portrait of the transitoriness, randomness, swiftness, frustrations and quicksilver beauty that are the essence of light. It is a work to be enjoyed, pondered over, engaged with, provoked by; to be packed in the rucksack of every walker heading for the sea or the hills, or to be opened to bring that outside radiance within four dark town walls.Lifescapes by Ann Wroe is coming in August 2023.
