Treacherous Old Father Thames

While its shape is famous — prominent on maps of London and Oxford — the Thames is ‘unmappable’, according to Diane Setterfield, because it not only ‘flows ever onwards, but is also seeping sideways, irrigating the land to one side and the other’. In Once Upon a River, she redefines the boundaries that separate land and water. The Thames ‘finds its way into wells and is drawn up to launder petticoats and to be boiled for tea’ and ‘from teapot and soup dish, it passes into mouths’.

Setterfield places the Thames all around, underneath and inside her characters — it nourishes their crops but also destroys them; it hydrates people but drowns them. It’s an understatement to say that the river is a character in this novel. It is more a god — powerful, changeable, violent and mysterious.
