In one of the most famous last lines of modern poetry, Seamus Heaney resolves to use his pen as a spade and excavate.
Like many poets, Heaney is drawn to archaeology.
Christine Finn, an archaeologist and poet herself, explores the connections between these two crafts.
She visits the bogs of Jutland, whose Tollund man inspired Heaney.
At a recent dig, with the poet Mario Petrucci, she tested the links between the poetic and archaeological process.
Petrucci's new poem, Terranauts, written as a result, is heard here for the first time.
