A detailed 1674 etching by Gerard de Lairesse depicting the diplomatic conclusion of the Third Anglo-Dutch War through classical allegory.

This etching by Gerard de Lairesse functions as a visual record of the 1674 Treaty of Westminster, which concluded the Third Anglo-Dutch War. Lairesse, a prominent figure in the Dutch Golden Age, employs a complex architectural framework to organise the composition. The scene is structured like a stage set, with classical columns framing a central interior where the diplomatic proceedings occur.

Above the central arch, a celestial arrangement features a personification of Peace, flanked by putti holding medallions that depict the portraits of the key monarchs involved in the negotiations. The upper corners are occupied by winged figures blowing trumpets, a traditional iconographic device used to announce the cessation of hostilities. Below, the foreground is populated by reclining male figures and decorative reliefs that provide a sense of classical grounding to the contemporary political event.

Lairesse demonstrates his mastery of the etching medium through the varied line work, which differentiates the textures of the stone architecture, the soft clouds, and the drapery of the figures. The composition relies on a rigorous sense of perspective, drawing the viewer's eye toward the central table where the treaty is signed. This work is characteristic of the artist's later career, during which he moved away from the earlier Rembrandt-influenced style toward a more structured, classicist approach. The print serves as a historical document, capturing the formalised language of seventeenth-century diplomacy through the lens of classical allegory. It reflects the period's preference for using mythological and historical motifs to legitimise and commemorate political agreements between European powers.
