The panel, executed upon the occasion of the 200th anniversary of the battle of Vienna, shows the arrival of envoys - Count Wilczek from Emperor Leopold I of Austria and the papal nuncio Pallavicini - at the court of John III with a plea for assistance for Vienna besieged by Kara Mustafa. The scene takes place in a spacious audience hall, with the king sitting on a centrally placed throne surrounded by court dignitaries and with the envoys kneeling at his feet. The panel was executed in the workshop of Baruch Dornhelm, the most renowned representative of a family of goldsmiths from Lviv specialising in the production of copies or, in simpler terms, forgeries of seventeenth- and eighteenth-century European artefacts. The seventeenth-century town marks of Gdansk, visible along the edge of the bannel, are to suggest an earlier origin, but this is not a copy of a Baroque work of art since it was made during the nineteenth century. A rare example of a product, whose degree of technical complexity testifies to the craftsmanship of the makers.
