The river takes charge of Dr Simon Park’s poetic intervention.
One of my works at “Exploring The Invisible”, Trinity Buoy Wharf. A photographic process that uses the microorganisms naturally present in natural water courses to make living images. To make these, I took water taken from the Thames, and used this to infuse a paper canvas. Next, I differentially exposed the medium to light, using a negative image, so that the normally invisible photosynthetic microbes naturally present in the water, would grow in the illuminated areas to form a poem, written in a living green ink which has arisen from the river water itself. Nature is capricious though, and the Thames seems to have censored the intended message, and created its own interpretation. Here are the words of the original poem: Grey Thames at flood in balance swung, Grey gulls scared mewing overhead, The chill grey wind a requiem said, And over all the grey sky hung. Mortlake Bridge, Fred S Thacker, 1920
