The word “mapping” usually gets my attention, so I was intrigued to read Laurence Fearnley’s Corpus post, Scent mapping, Signal Hill. I imagined that she would have created a depiction of Signal Hill with delineated areas where certain scents predominated, probably colour-coded and overlapping syllogistically in places. In other words, scents experienced in real life would be mapped to defined areas on a small scale pictorial representation of real life. Captions would be along the lines of “Here be lavender,” and “Bracken, with the bouquet of gorse in season”. This was a map that I really wanted to see, and to sniff at. But Laurence’s article and a subsequent email disabused me. She saw her map as “dynamic rather than static, with ‘map’ being more of a verb than a noun.” More along the lines of what Alfred Gell refers to as a “mental map”: a process, not a picture. The Signal Hill scent map existed in Laurence’s brain, not on paper.
