Feu follet is French for firefly - the source of delicate bursts of lightning on summer evenings.
Those evanescent flashes in the landscape and what they evoke about illumination and impermanence inspired the title for Liz Rideal's new book and exhibition.
In Feu Follet, the artworks respond to the subterranean crypt space of St John's, focusing on the ambiguous and offering momentary glimpses of fleeting subject matter.
The brief trails of seemingly airborne colour appear to arrest time in this atmospheric space.
Throughout the exhibition Rideal continues her investigations into artistic analogies, offering a conversation among digital photographs printed on silk, video and large watercolour abstract painting.
