Esquisse de détail pour l'Hôtel de Ville de Paris : La voûte d'acier, silhouette du marquis de Lafayette

Jean-Paul Laurens's sketch studies a steel vault — likely an architectural metaphor for revolutionary-era achievements — alongside the silhouette of the Marquis de Lafayette, the French general who fought in the American Revolutionary War and became a symbol of Franco-American friendship. Lafayette's inclusion in the Hôtel de Ville's decorative program acknowledged the transatlantic dimensions of French revolutionary ideals. The 1889 program, coinciding with the Revolution's centenary, inevitably engaged Lafayette's legacy as a bridge figure between the two great republican traditions of the late eighteenth century.

The sketch combines architectural study — the structural vault rendered in confident linear perspective — with the figural silhouette of Lafayette, whose profile was iconographically established through decades of commemorative imagery. The composition juxtaposes structural power and historical memory.
