His work is defined by the technical precision of the French school of engraving. Lombart translated the paintings of Anthony van Dyck into monochrome prints with clarity. In portraits like those of Antoine, Duc de Gramont or the Earl of Pembroke, he used controlled hatching to define texture. His illustrations for the Aeneid demonstrate his ability to manage narrative scenes within a classical framework.

Modern collectors value Lombart for the formal structure he brings to a space. His prints offer a sense of historical weight without the clutter of later styles. The clear linework and compositions of pieces like the Supper at Emmaus suit contemporary interiors that favour clean lines. These works offer a direct example of the seventeenth-century Baroque movement through a disciplined medium.
