Shortly after I began teaching on the creative writing programme at Middlesex University, Shena Mackay was appointed as our Honorary Visiting Professor. Her inaugural lecture in 2001 was titled A Horror of Sunsets: The Writer’s Palette and the Enemies of the Imagination. This referred to a line from Proust: ‘I have a horror of sunsets: they’re so romantic, so operatic.’ I’ve never got on with opera myself, not being able to let the music sweep me past the banality of the plots, but I knew at once I would get on with Shena Mackay. Her subject was synaesthesia, a condition from which she suffers, if ‘suffers’ is the right word. I suspect not – ‘inhabits’, perhaps. In her case, it means seeing words or individual letters in colours.
