Giordano Bruno, born in 1548, was a radical thinker and heretic whose ideas challenged the Catholic Church's doctrines.

Embracing a boundless universe with countless worlds, he defied traditional views and even rejected core Christian teachings. After fleeing from the Dominican Order, Bruno became a controversial figure across Europe, ultimately leading to his arrest by the Inquisition.

He refused to recant his beliefs, resulting in his execution by burning in 1600—a martyr for the cause of free thought whose legacy endures today.
