The Salzburg landscape series for Prince-Archbishop Count Hieronymus Colloredo: Hohensalzburg

His commission for Colloredo was probably thanks to two circumstances: his acquaintance with the court gallery inspector, painter and encaustic specialist Andreas Nesselthaler from Rome, and his Italian etchings, "Mahlerisch radierten Prospecte von Italien".
This series is amongst the principal Salzburg landscape paintings of the time, heralding 19th century Austrian landscape painting, which achieved international significance. All four pictures are signed and dated: "Gaisberg Landscape" and "The Salzach Valley to the south of the town" (1796), "Thundery Landscape with Hoher Staufen" and "Hohensalzburg" (1797). The rendering of the different times of day and the mood lighting has particular charm; in the warm light of the setting sun, the distinctive countenance of the town of Salzburg, crowned by "Hohensalzburg" Fortress, is a felicitous conclusion to the series.
