He also produced a long poem, The Myth of the Rock, of a spiritual nature. His daughter, Oriole Parker-Rhodes, has electronically published some of the stories he told to his children. The library of the Society of Friends in London holds a typescript "The wheel of creation : an essay in wholesight, towards a coherent model of the place of mankind in the cosmos"
