In the politically charged era following the 1801 Act of Union, when Ireland's harp symbol was ubiquitous in political imagery, the playable instrument, the Gaelic harp, had largely disappeared. John Egan, a self-taught inventor, conceived a new national instrument, the "Portable Irish Harp," with innovative mechanisms to expand the harp's chromatic capabilities. The template for the modern Irish harp, Egan's design was imitated a century later by several principal harp makers. Antique Egan harps, prized as rare cultural artefacts and art objects, survive in museums and private collections worldwide. The included illustrations and the "Catalogue of Egan Harps" are an invaluable resource. This book on Ireland's renowned harp maker, John Egan, and the Egan family firm, reveals the significance of Egan harps in shaping Irish harp history.
