Krystyna Czerni, the monographer and researcher of Jerzy Nowosielski’s work, wrote numerous times that the painter had the ability to ‘direct sacral interiors’, assigning a role to painting while at the same time skilfully harmonising it with the architectural space. The Biały Bór Orthodox church is a perfect and the most complete proof of this, but it is not the only one. There was another prominent artist who happily cooperated with Nowosielski, one endowed with an extraordinary skill in creating sacred spaces – the architect Stanisław Niemczyk. The interior of the Church of the Holy Spirit, which he designed in the late 1970s in Tychy, is Nowosielski’s creation.
Covered by a vast, sloped roof that flows down almost to the ground, is a centrally planned space surrounded by slanted wooden walls covered with polychromes, well-lit thanks to a skylight, cut into the top of the roof, through which sunshine falls directly onto the centrally situated altar. Although here the artist created ‘only’ the wall paintings, one can’t help but feel that they resulted from an in-depth understanding of the architecture itself, of the spatial solutions proposed by Stanisław Niemczyk. The simplicity and uniformity of the forms employed by Nowosielski prevent his paintings from dominating over the architectural structure, causing them to harmoniously supplement it instead. The painter didn’t steer clear of vivid colours, and they are what provide an extraordinarily interesting complement to what are usually monochromatic sacral interiors.
In the neo-Romanesque Church of Divine Providence in the Wesoła district of Warsaw, paintings cover only the apse (the semicircular enclosing of the chancel) and the narthex (the vestibule under the choir) – the former are maintained in red tones, while the latter are dark blue; they’re complemented by multicoloured stained-glass windows and dark, almost monochromatic Stations of the Cross. Nowosielski created these artworks in the 1970s, almost half a century after the church was built. He was invited to do so by the parish priest, who decided that the artist’s uniform, raw paintings would give an appropriate finish to the almost minimalist structure of the 1930s church.
