Pure Filth, Aidan Mathews' fifth volume of poetry, follows upon Windfalls (Dolmen, 1977), Minding Ruth (Gallery, 1983), According to the Small Hours (Cape, 1998) and Strictly No Poetry (Lilliput, 2017). At its heart, the collection is about reflections on a career and sustained loves for people, God and art, with themes threaded throughout such as the pandemic, suburban Dublin, Irish landscape and history and the Holocaust.
