Thomas Jefferson called him the greatest poet who ever lived, Napoleon carried his verses into battle, and he never existed. This episode explores the phantom third-century bard Ossian and the ambitious Scottish poet James Macpherson who published his supposed fragments in 1760, then returned from the Highlands with a full epic about the warrior Fingal. It sets the hoax against an Enlightenment audience exhausted by classical rules and hungry for a Northern Homer.

The conversation traces the continental frenzy that inspired Schubert, Mendelssohn’s Hebrides Overture and Ingres’s painting for Napoleon’s bedroom, and explains how a suggested godson’s name produced King Oscar I of Sweden and Norway. It then follows the backlash: Irish historians who recognized Fionn mac Cumhaill beneath Fingal, Samuel Johnson’s brutal attacks and the Gaelic poets who answered him in verse, Hugh Blair’s defense, and the twentieth-century scholarship of Derek Thomson that exposed Macpherson as a remix artist who reverse-engineered fake Gaelic originals from his own English.
