In this collection Marsh moves via Kepler and Darwin into a celebration of nature, searching within our secular world to 'find a language' to render its mystery and concludes by touching on the great challenges we now face. Following The Guidman's Daughter with his poems on Mary, Queen of Scots, Marsh begins this new collection with a sequence exploring the life and times of John Knox, locating this ambivalent figure in the turmoil of the Scottish Reformation. Marsh moves via Kepler and Darwin into a celebration of nature, searching within our secular world to 'find a language' to render its mystery and concludes by touching on the great challenges we now face. Our striving to understand the nature of things hints, perhaps, at the possibility of a different kind of redemption.
