Première idée pour le vieil Horace de "Serment des Horaces"

David's Première idée pour le vieil Horace of 1775, the earliest preparatory sketch for his eventual masterpiece The Oath of the Horatii, demonstrates the working process through which his mature compositions developed over years of revision and refinement. The sketch belongs to his Roman period studies and shows the kernel of the compositional idea — the old man, the oath, the women's grief — that would eventually be distilled into one of French painting's most influential works. Such working drawings document the creative process behind his apparently severe finality.

The study is painted with vigorous, rapid brushwork that establishes the basic forms without final refinement. Comparing this to the finished Louvre painting reveals how David tightened the drawing, clarified the lighting, and strengthened the geometric structure of the final composition.
