SCHMUTZER, Jakob Matthias (1733-1811) - WAGNER, Joseph (1706-1786), by Martin van Meytens the Younger (1695-1770). Portrait of Count Giacomo Durazzo. About 1765. Rare proof of the great portrait of Giacomo Durazzo (1717-1794), diplomat, theater man and among the greatest collectors of eighteenth-century prints. The slab, begun in Vienna by Jakob Matthias Schmutzer from a painting by Martin van Meytens the Younger, was later completed in Venice by Joseph Wagner. In fact, in the final state it has the inscriptions "Le C. Jacques Durazzo / Ambassadeur Imperial / à Venise en MDCCLXV Of particular interest, this impression documents an intermediate phase of the workmanship of the slab: the face, the background, the library and much of the elaborate architectural and rocaille frame are already defined by a thick dash, while large areas of the garment, the hands, the armchair and various ornamental details remain in saving or just outlined. Etching and burin on wired paper. Test ahead letter and before completion of the plate, with margins (minimum defects). (1)
