For a century and a half, the reputation of the Irish poet, James Clarence Mangan (1803-1849), has been based mainly upon a small number of poems, and a biographical tradition that cast him as a tortured genius. Yet his achievement as a whole was much more complex and varied, ranging across over 900 poems and a significant amount of creative and critical prose. In this comprehensive single-volume selection of Mangan's poetry and prose, Mangan can be appreciated for his poignancy and power, his astonishing metrical skills, his love of wordplay, and his surrealist humor. He emerges here as a witty and intelligent craftsman as well as an emotionally-charged romantic, and his audacious experiments with translation and parody make him seem remarkably contemporary. Also, Mangan's fascinating prose commentaries are restored to their original positions surrounding his poems, and readers are for the first time given a generous selection of Mangan's critical writing and letters.
