At a time when the old order begins to collapse and Europe braces for Napoleon’s advance, Istria still remains under the rule of the Venetian Republic. In this peripheral space of power and faith emerges Martin Vellović — a charismatic parish priest who gathers people through knowledge, belief, and the promise of truth.

His power does not rely on violence, but on conviction — and that is precisely what makes him dangerous. As belief in him grows, institutional authority weakens.

Venice dispatches cavaliere Marco Antonio Mattei to investigate alleged miracles. What begins as a routine inquiry gradually turns into a confrontation with fanatic conviction, enforced silence, and loyalties that operate beyond the law. Within a closed system where faith becomes a mechanism of power, the boundary between sanctity and threat slowly dissolves.

Based on documented events and archival traces from the late 18th century, The Black Oath is historically grounded fiction examining authority, guilt, and responsibility — in a world where truth does not liberate, but destabilizes power.

“A complex story, a dynamic writing style, and a rich vocabulary enhance the sense of originality when combined with a universally accessible plot.” — Boško Picula, film critic
