‘Valleys breathe, heaven and earth move together,/ daisies push inches of yellow air, vegetables tremble,/ grass shimmers green…’ The characteristic undulations of the voice of the Beat poet Allen Ginsberg greet the visitor on entering Wales Visitation: Poetry, Romanticism and Myth in Art at the National Museum Cardiff. Bearded and mellifluous, projected to mythic proportions across a vast expanse of wall, Ginsberg is seen reading his poem ‘Wales Visitation’ on American television in 1968, telling less of visits than of visions.
