In this issue the oldest known works of representational art – stone carvings – become the source material for the artist Tacita Dean and the photographer Boris Mikhailov. Where he extracts from the stone, she adds – collaging, colouring and manipulating. Where Boris pulls the human from the natural, Tacita brings the human in, offering a sense of place and location. Dean herself describes their collaboration as follows: "Perhaps what we are doing here with our rock voodoo is trading in respect for each other’s unselfconsciousness across a continent and a society of difference."
