NO rest for "sleep" artist Susan Aldworth, who now has two exhibitions running in York.

As featured in The Press already, her flotilla of 414 embroidered pillowcases, plus sculptures, monoprints and a film, will be on show at York St Mary's, Castlegate, in The Dark Self exhibition until September 3.

Now, more of her monoprints can be seen in The Art Of Sleep at Lotte Inch Gallery, in Bootham, until July 21. "Susan Aldworth is an artist interested in questions of human identity," says Lotte. "This intriguing show of exquisitely detailed, wonderfully mysterious and often ethereal works shows Susan's working practice at its most experimental and beautiful," says Lotte.

Aldworth is a printmaker and filmmaker who references philosophy, medicine, and neuroscience in her work. She has spent the past three years as artist in residence at the University of York, working on an interdisciplinary project with Professor Miles Whittington, chair in neuroscience, and Professor Michael White, head of the department of art history.

Professor Whittington and his team are working on a Wellcome Trust grant carrying out research into what happens within the brain during deep sleep: a time when our brain renders us unconscious. For Aldworth, this poses a philosophical conundrum: “If our brains can make the ‘self’ unconscious, then what is the relationship between the brain and our sense of self?” she asks.

The Art Of Sleep offers an insight into the first stages of Aldworth’s artistic questioning and presents a body of work produced in preparation for The Dark Self.

Lotte Inch, by the way, was responsible for designing the frankest of the 414 embroidered pillowcases now hanging from the ceiling in the Nave of York St Mary's: the one that reads Stop ******* Snoring. "Blame the snoring husband!" she says.
