Northern landscape with fortress 

The Russian painter Nicholas Roerich is known for his mystical landscapes and his interest in the Himalayas, which is reflected in the artwork, *Northern landscape with fortress*. Roerich's use of color, line, and form creates a sense of depth and distance, capturing the vastness of the mountains and the serenity of the valley below. The fortress, a symbol of strength and protection, dominates the foreground, while the winding river adds a sense of movement and tranquility. The painting, likely from Roerich's later career, showcases his signature style - bold, simplified forms and luminous colors that inspire a sense of wonder and awe.
