The artwork titled “Costume devotion of Fiery Furnace before Christmas Liturgy in Russian Orthodox Church” was created by Nicholas Roerich in 1907. The piece employs gouache, Indian ink, pencil, cardboard, and tempera as mediums and belongs to the Art Nouveau (Modern) movement. With dimensions of 63 x 49 cm, it is categorized as a genre painting and is housed in the Tretyakov Gallery in Moscow, Russia.
The artwork presents an exquisitely detailed and vibrant depiction of a religious scene within a Russian Orthodox Church. The central focus is on a ceremonial structure surrounded by what appears to be clerics or parishioners, all attired in ornate costumes that suggest devotion and reverence. The use of rich and dark tones gives the scene an almost mystical quality, enhanced by the intricate architectural elements and divine figures, such as angels depicted in the upper section of the artwork. The attention to detail and texture vividly captures the solemn and sacred atmosphere of the pre-Christmas liturgy.
