Matthew Francis-s latest collection celebrates the richness of nature and of our responses to it. The pleasures of summer are emblazoned in the colourful wings and evocative names of butterflies, while a nocturnal encounter with an earwig becomes a joyous incantation to the -witchy-beetle, forkin-robin- of dialect. Francis''s love of history, embodied in his acclaimed Mandeville and The Mabinogi, gives rise to a sequence based on Robert Hooke-s microscopic observations. There are tributes to the poets Basho, Dafydd ap Gwilym and W. S. Graham, to fireworks, apple varieties and hot toddies. And, in a moving elegy for a friend killed in a parachute accident, Francis shows us a vertiginous vision of a world where even the dead -sleep on the wing-.
