Christopher Meredith's Air Histories starts in the Stone Age and ends in the future. It's marked by formal diversity and a wide range of subjects, with the personal alongside the impersonal and the experimental alongside well-known forms, as well as including some translations from the Welsh. Throughout it engages the rich meanings of its title, touching on the elemental and on historical time, as well as music and story, meditating on human creativity and its fallibilities from knapping an arrowhead to playing the fiddle or making a guitar. Nature is a touchstone, particularly the Black Mountains, near the author's home, but also often seen 'aslant' as in 'Seeing the Birds' where sparrows seem suddenly fierce as eagles.
