The Boy Who Wouldn’t Bow: François-Jean de la Barre and the Hat That Changed France

On 1 July 1766, a nineteen-year-old French nobleman named François-Jean de la Barre was tortured, beheaded, and burned in the public square in Abbeville. His crime? Failing to remove his hat during a religious procession. This episode examines the de la Barre affair, a case that horrified Voltaire and became a defining example of religious intolerance in eighteenth-century France. We trace how a young man’s irreverence collided with institutional power, how a copy of Voltaire’s Dictionnaire philosophique was nailed to his body as it burned, and how his execution helped fuel the Enlightenment arguments for reform. We also visit three other moments from this date: Lexell’s Comet in 1770, which remains the closest any comet has ever come to Earth in recorded history; Queen Urraca of León, who inherited the crown in 1109 and became the first woman to rule independently in medieval Europe; and the 2025 discovery of 3I/ATLAS, the third known interstellar object to pass through our solar system. From the cruelty of conformity to the quiet passage of cosmic visitors, this is history that asks uncomfortable questions and refuses simple answers.

Chapters

• Intro Clara Vale introduces a day in history marked by dangerous ideas, religious conformity, and a nineteen-year-old nobleman executed for not taking his hat off in eighteenth-century France.
• The Boy Who Didn’t Bow The story of François-Jean de la Barre, the young nobleman accused of blasphemy and sacrilege in 1765 Abbeville.

• Lexell’s Comet, 1770: The Closest Visitor On 1 July 1770, Lexell’s Comet passed within 2.18 million kilometres of Earth, the closest approach of any comet in recorded history. Discovered by Charles Messier and calculated by Anders Johan Lexell, the comet has not been seen since after a subsequent encounter with Jupiter altered its orbit.
• Queen Urraca of León, 1109: The First On 1 July 1109, Urraca inherited the crown of León and Castile, becoming the first woman in Europe to exercise independent rule as queen regnant. Her turbulent reign lasted nearly two decades despite opposition from nobles and the Church.
• 3I/ATLAS, 2025: The Stranger On 1 July 2025, astronomers announced the discovery of 3I/ATLAS, the third known interstellar object ever detected, following ‘Oumuamua in 2017 and Borisov in 2019. The object’s origin and nature remain under investigation.
• Outro Clara reflects on the day’s stories, from institutional conformity to cosmic visitors, and how the ideas François-Jean de la Barre was accused of sympathising with ultimately outlasted the pyre.
