The subject of this work is the monumental art of Jerzy Nowosielski (1923–2011), one of the most outstanding contemporary Polish painters, who combined modernity with the orthodox icon aesthetics. This work discusses the monumental realizations of Nowosielski, especially the architectural polychromes made by the artist in Catholic and Orthodox churches in Poland in the years 1950–1999. The aim of the inquiry is to present his work theoretically and place it in a broader artistic context. The research shows that Nowosielski’s monumental works results from a strongly defined artistic concept aimed at ‘mystagogy of space’. Nowosielski’s work is an original synthesis of the modernist avant-garde and traditional canons of religious art. The analysis of the problem was carried out in two areas: (1) analysis of the artist’s theoretical statements; (2) analysis of the artistic form with particular emphasis on the color aspect, based on the example of selected churches in Wesoła, Tychy, and Biały Bór. The work uses comparative references to the ideas of Wassily Kandinsky, Kazimir Malevich, Piet Mondrian, and Le Corbusier.

不可言喻的色彩——耶日·诺沃谢尔斯基的不朽作品作为对神圣空间的当代探索

这件作品的主题是耶日·诺沃谢尔斯基（Jerzy Nowosielski，1923-2011 年）的不朽艺术，他是当代最杰出的波兰画家之一，将现代性与正统的偶像美学相结合。这部作品讨论了 Nowosielski 的巨大成就，尤其是艺术家在 1950 年至 1999 年间在波兰的天主教和东正教教堂制作的建筑彩绘。调查的目的是从理论上介绍他的作品，并将其置于更广泛的艺术背景中。研究表明，Nowosielski 的不朽作品源于一种旨在“空间神秘学”的强烈定义的艺术概念。Nowosielski 的作品是现代主义先锋派和传统宗教艺术经典的原始综合体。对问题的分析从两个方面进行：（1）艺术家的理论陈述分析；(2) 以 Wesoła、Tychy 和 Biały Bór 的选定教堂为例，分析艺术形式，特别强调色彩方面。该作品使用了对瓦西里·康定斯基、卡齐米尔·马列维奇、皮特·蒙德里安和勒·柯布西耶的思想的比较参考。
