A detailed historical etching by Pierre Gabriel Berthault documenting the 1789 blessing of the National Guard flags inside Notre Dame Cathedral.

This etching by Pierre Gabriel Berthault depicts the ceremonial blessing of the National Guard flags within the nave of Notre Dame Cathedral. The event occurred on 27 September 1789, a period of significant political transition in France. Berthault, a skilled engraver, captures the architectural scale of the cathedral with precision, using linear perspective to draw the eye toward the distant altar.

The composition is structured by the rhythmic repetition of the massive columns that line the nave. Flags are suspended from the pillars, creating a sense of order and solemnity. Below, the ranks of the National Guard stand in formation, their presence filling the space with a disciplined, military atmosphere. The artist employs fine cross-hatching to define the shadows of the vaulted ceiling and the textures of the stone architecture, providing a clear sense of depth and volume.

Berthault was known for his contributions to the 'Tableaux historiques de la Révolution française', a series of prints documenting the events of the French Revolution. This work functions as a visual chronicle of the era, recording the intersection of religious ritual and revolutionary civic identity. The print avoids excessive ornamentation, focusing instead on the clarity of the scene and the architectural grandeur of the setting. By documenting the specific arrangement of the ceremony, the artist provides a window into the public spectacles that defined the early years of the revolutionary period. The work is a technical example of late eighteenth-century engraving, demonstrating the capacity of the medium to render complex interior spaces with accuracy and restraint.
