This is a set of 15 images of the surface of the River Thames, which flows through central London. It captures the astounding diversity in what people often think of as simply a single body of water. Look closely and you will find the images dotted with tiny numbers, which connect to footnotes below the photographs. In the footnote text, Horn’s ideas are interwoven with various emotions and questions evoked by the depth and rippling surface of the water, disturbing tales associated with the river, literary quotations from Emily Dickinson and more. In this work, Horn asks us: “When you see your reflection in water, do you recognize the water in you?” Water is an indeterminate substance, both familiar and strange, which flows through and fills all our bodies.
