Wyspiański pioneered the symbolism movement in Polish art in a way that was distinct from that of Jacek Malczewski. Between 1892 and 1894, while still in Paris, he made a cardboard model of a stained glass window titled Śluby Jana Kazimierza (The Vows of John Casimir), intended for the cathedral in Lviv (the project was never realised). This monumental painting became a manifestation of symbolism rooted in a historiosophical vision, synthesising and reinterpreting the Polish past. Morphologically, the stained glass design drew on medieval art, which inspired both the Romantics and the Neo-Romantics of the nineteenth century. The concept of a complex, vertically stacked composition encompassing the worldly dimension (the wedding of King John II Casimir in the cathedral) and the visionary dimension (a symbolic representation of the falling Polish diaspora, watched over by the Virgin Mary) was derived by Wyspiański from Gothic polychromes and stained glass windows. He became acquainted with their artistic form while collaborating with Matejko on the restoration of St. Mary’s Basilica in Kraków during 1890-1891.
In Kraków, Wyspiański created an innovative approach to decorative painting that was unprecedented in European art. He conveyed his vision of a sacred interior through a series of polychromes and stained glass windows designed between 1895 and 1897 for the Franciscan church. Although the planned iconographic programme was not entirely realised, the artist gave perfect visual form to the idea of the sacrum, which was born in his imagination during his ‘pilgrimage’ to the great cathedrals of Gothic Europe. This is where the modern concept of stained glass, rooted in the Middle Ages and also influenced by contemporary Parisian designs, crystallised. Wyspiański remembered the details of the cathedrals in Paris, Chartres, Strasbourg, Nuremberg, and Prague – structures he had studied carefully and sketched in 1890 with the aim of writing his doctoral thesis on Gothic architecture.
However, when designing stained glass windows for the Franciscan church, he went beyond the norms of medieval tradition. By breaking with the strict convention of dividing the stained glass fields into a series of small panels, he introduced an unconventional approach in Poland – treating the glass panes as a painting surface. This new understanding of monumental form in art was supported by Puvis de Chavannes, who created the overstylised frescoes decorating the Pantheon in Paris, as well as by the English Pre-Raphaelites, who revived the artistic conventions of the early Renaissance.
Wyspiański’s Franciscan polychrome was also astonishing in its originality. The artist adorned the church walls with motifs of flowers, herbs, and cereals, transforming it into a multicoloured ‘vestibule of paradise’. The plant forms, meticulously studied by Wyspiański in his Zielnik (Herbarium) during his excursions to the Kraków countryside, were transformed here into linear patterns. This microcosm reflected the Franciscan celebration of nature, as well as the belief, typical of symbolists, that every part of nature, even the tiniest, is permeated by a spiritual element. Poverty, humility, charity, religious zeal, and mysticism are the ideals that Wyspiański depicted in the stained glass windows and polychromes of the chancel. A stained glass window depicting the founder of the order, St. Francis of Assisi, and another stained glass window featuring Blessed Salomea, a Polish Franciscan nun, understood as its pendant, constitute the ideological core of this part of the iconographic programme, which pertains to the realm of worldly existence.
The synthetically rendered figures of both saints fade away among the plant shoots: Salome’s silhouette is encircled by an ornamental bordure woven from flowers, leaves, and stems, while the hieratic figure of St. Francis is trapped among the thorny branches of a rose bush. The ascetic figures of the saints bear witness to their complete renunciation of worldly possessions in favour of serving God. Both are depicted in a state of mystical ecstasy, captured at the moment of crossing the threshold of transcendence.
The idea of hierophany – a manifestation of the sacred – was depicted by Wyspiański on the wall of the chancel, showing the Virgin Mary with the Child being crowned by two wingless angels. The peasant features and Kraków costume of the Madonna reflect the artist’s faith in folk, understood as an enclave of spiritual purity and the cradle of religiosity. At the same time, the idea of the Virgin Mary, Queen of Poland, who mystically watches over the nation, as shown in the design for the stained glass window Śluby Jana Kazimierza, is repeated here. The Franciscan Madonna is also the Apocalyptic Madonna, the ‘Lady clothed with the sun’, encircled by a fiery halo and a ‘wreath of twelve stars’, shielding the Child with a veil out of fear of Satan.
