James Macpherson's "Poems of Ossian", first published from 1760 as Fragments of Ancient Poetry, were the literary sensation of the age. Attacked by Samuel Johnson and others as "forgeries", nonetheless the poems enthralled readers around the world, attracting rapturous admiration from figures as diverse as Goethe, Diderot, Jefferson, Bonaparte and Mendelssohn. This International Companion examines the social, political and philosophical context of the poems, their disputed origins, their impact on world literature, and the various critical afterlives of Macpherson and of his literary works.
