Dià (from the Greek διά, “through”) is a sculpture that merges the dimensions of silence and sound. Shaped as a golden ratio double horn, the piece invites spectators to listen to and observe the surrounding landscape. Its two cavities function as a megaphone or a viewing lens, transforming the sculpture into an interactive device that sparks an intimate dialogue between people.

Commissioned in 2016 for the Walking Art project, the artwork was originally installed in a no man’s land on the summit of Mount Pal Piccolo (1780 m), right on the Italian-Austrian border where World War I was fought. Its purpose was to symbolically connect the frontline trenches, both visually and acoustically. Whereas horns and trumpets were once used to sound offensive battlefield charges, issue orders, or spy on the enemy, Dià cancels out their military function—duplicating and fusing them into a single structure that connects two separate spaces, ultimately urging dialogue through speech.

Today, in an era marked by geopolitical fragmentation, border closures, and the rise of new walls, the message of openness and dialogue embedded in Dià feels more urgent and relevant than ever.
