Tacita Dean’s screenprint ‘Foreign Policy’ is an interpretation of a similarly titled large-scale work drawn in chalk on blackboard from 2016. A self-declared collector of clouds, Dean began this body of work in 2014 following her move from Berlin to Los Angeles. She describes a seminal encounter with a ‘voluminous atomic cloud blooming’ across Sunset Boulevard ‘on pure azure without transitional haze nor other, lesser clouds for company’. Since declaring California as ‘the place for clouds’, the artist has drawn them in chalk on blackboards and spray chalk on slates, ‘found them on postcards, painted round them, photographed and printed them.’ ‘Foreign Policy’ (2016), which was drawn specifically with its destination in the Foreign Office in mind, simultaneously evokes the challenge of capturing the mutability of clouds and an epoch of unprecedented global change and uncertainty.
