This cahier presents new work by the celebrated Irish poet Paul Muldoon. After a preface in which the poet explains what for him is the importance of translating, there follow four original works: 'The Windshield', 'Balls' (a five-sonnet sequence), 'Quail', and the title series of poems, 'When the Pie Was Opened'. Interspersed with these are the poet's translations: from Latin, from Anglo-Saxon, from Medieval Welsh, from Greek, and from Irish. The cahier is completed by drawings and an etching by the Sicilian artist Lanfranco Quadrio.
