The Artistic Reconstruction of a Ghost Migration

The migration of the Helvetii in 58BC remains one of the most significant yet archaeologically invisible events in the history of the Swiss Plateau. Julius Caesar, whose Gallic War commentaries serve as the primary source for the event, claimed that hundreds of thousands of people burned their homes to begin a journey toward southwestern France. Despite the scale described, modern archaeology has found no material traces of the massive convoys or their path. To bridge this gap, the Roman Museum in Avenches has turned to a photographic medium, using the work of Yves André to materialize a historical narrative that has otherwise vanished from the physical record.

Caesar’s Narrative and the Burgundy Defeat

According to Roman accounts, the Helvetii sought to escape Germanic pressure by relocating to Saintonge, a region on the Atlantic coast. Caesar used this movement as a legal and military pretext to launch his intervention in Gaul, eventually crushing the Helvetian forces at the Battle of Bibracte in present-day Burgundy. The survivors were famously forced by the Roman army to return to their original territories to serve as a buffer zone against northern tribes. Museum director Denis Genequand notes that photography serves as an essential tool for interpretation here, allowing the public to visualize the scale of a journey that left no ruins or relics for researchers to excavate.

A Three Part Itinerary of Hope and Defeat

The exhibition is structured as a visual journey divided into three distinct chapters. The first series of photographs illustrates the outward migration, pairing images of untouched landscapes with views of the same locations as they appear in the modern era to contrast the passage of time. The second chapter, composed of large black and white photographs, focuses on the forced return of the defeated tribe through the Jura passes, utilizing a somber palette to evoke the psychological weight of their failure. The final section centers on vibrant, large scale color images of Saintonge, representing the "dream Helvetia" that the migrants sought but never managed to settle.
