The impressionist experience is fully reflected in his late works around 1890, when he switched from oil to pastel. In this technique, the artist repeated several earlier oil compositions, including All Souls’ Day.
One of the breakthrough moments in Pruszkowski’s career was his stay in Mogiła near Kraków, where the artist, together with Leon Piccard, created paintings in the chapel of the Cistercian monastery. The time spent in Mogiła resulted in an increased interest in folk themes, as well as the establishment of closer relations with the local peasants. Eventually, in 1882, Pruszkowski moved to the countryside from Kraków, to Mników, where he created rural genre paintings, portraits and paintings illustrating folk beliefs. After moving from Kraków, he started to dress ‘like a Cossack’, he made friends with the local inhabitants, and he roamed the surrounding fields and forests during daytime and night-time excursions on horseback.
In Pruszkowski’s case, his fascination with folk culture, as evidenced by, amongst others, the All Souls’ triptych, went beyond a superficial love of folklore. With ‘feeling and faith’, the artist tried to come closer to a folk perception of the physical and metaphysical world. Thus, the motif of All Souls’ Day under Pruszkowski’s brush acquires a unique character in comparison to other art of the period. In 19th-century painting, the theme of All Souls’ Day was not particularly popular, and when it was taken up, it was rather in the convention of a genre scene, in the form of mourners visiting a cemetery, as in the painting by a Czech painter Jakub Schikaneder (from the same year as Pruszkowski’s All Souls’ Day), which depicts a beggar woman praying by the cemetery wall. In Poland, additional scenes in cemetery scenery acquired a patriotic touch, for instance depicting mourning for an insurgent over his grave, as in the painting by Ludomir Benedyktowicz. Witold Wojtkiewicz’s watercolour All Souls’ Day, which refers to the motif of danse macabre, is a completely different, visionary and symbolic representation of the theme.
Pruszkowski, on the other hand, depicts only the phantom – he refrains from portraying the figures of mourners. He does not present the night of All Souls’ Day in the countryside with the cool eye of an ethnographer but pulls the viewer into the very centre of the action. Thus, the mood of Pruszkowski’s painting is closer to Young Poland’s ‘stiummung’ paintings, such as Chmielowski’s Landscape with a Phantom (also from 1888), presenting a figure of a pale female phantom emerging from a landscape bathed in evening mists at dusk, though in this case without the context of particular beliefs and legends, than to other representations of All Souls’ ceremonies. At the same time, Pruszkowski’s triptych not only uses the atmosphere of melancholy and horror, but also tells a fully-fledged story which takes place during the entire All Souls’ night, from dusk till dawn. Although the other two paintings have been lost, the story has survived in its literary form in Maria Konopnicka’s poem From That World, inspired by the triptych. The painterly vision of Pruszkowski, to a large extent based on literary foundations, found a worthy literary development in the poem itself:
