Since antiquity the colour blue has influenced world cultures, particularly around the Mediterranean as in the poet Homer's evocative image of the 'wine dark sea'. Blue was also the colour of the city of Athens, as an homage to Goddess Athena and her brilliant blue eyes. The elusive hue reveals itself at the edges of our world, at the farthest point of the horizon and the deepest stretches of the sea.

Blue has influenced our perceptions of the natural world, our cultural understandings, tapping into our deepest desires and affecting our emotions - or even the cause of history! This exhibition explores the many interpretations of Blue.
