The composition returns to an extraordinary episode of the early 1930s, when the Graf Zeppelin appeared above Lausanne and crossed the visual field of the Cathedral. The encounter joined one of the most advanced machines of its era with one of the principal monuments of the canton of Vaud.

At the time, the airship represented a new horizon of technical ambition and transcontinental movement. Its passage over Lausanne drew large crowds and remained present in local memory, principally through photographic traces and accounts transmitted across generations. The composition gives formal continuity to an event that might otherwise have remained outside the city’s recorded cultural memory.
