The painting executed by Alberto Pasini in Paris in 1864 and donated to the Academy of Fine Arts in Parma, depicts the sunrise in a vast region in the eastern deserts of Persia, on the road that leads from Shiraz to Isphan. In the foreground, where the nocturnal shadows still thicken dark, men and animals bustle among the lit fires of the bivouac, at the foot of a plateau that rises behind the camp, getting lost in an endless distance, closed on the horizon by a chain of purple mountains against the bright sky of the first light of dawn. Pasini expands the frame to the maximum to communicate all the sense of abandonment and luminous amplitude aroused in him by the Persian landscape, which much more than the figures, constitutes the true protagonist of the scene, restoring to the viewer the strong suggestion produced by the still vastness of the place. still asleep in contrast to the turmoil of the caravan preparing to leave. The references to painting rich in romantic and sentimental implications of the barbizonniers painters, who had influenced the painter's culture upon his arrival in Paris, are now completely outdated, in favor of a more analytical observation, which aims at an absolutely objective rendering of reality natural, devoid of picturesque compliments. Pasini's interest in oriental themes develops in close contact with the French cultural climate, already permeated for some time by the magical and adventurous charm of the lands of the East, but is enriched by the direct vision of extraordinary places, with shining colors , in the still and limpid light of the places, which he tries to transfer onto the canvas with a paint of solid coloristic impasto and a vivid and luminous palette, enhanced by strong tonal contrasts, marked by a subtle and very exact outline.
