Final answer:
Both artworks emphasize visual impact through bold and striking visual elements.
Step-by-step explanation:
A characteristic of both Triumphal Entry (a page from a manuscript of Firdawsi's Shahnamah) and Kazimir Malevich's Black Square is their emphasis on visual impact. Both artworks make use of bold and striking visual elements to capture the viewer's attention. In the Triumphal Entry, the detailed calligraphy and vibrant colors create a sense of grandeur and power, while Malevich's Black Square makes a bold statement through its simplicity and abstraction. Both artworks demonstrate the artists' intentions to create visually compelling works that provoke an emotional response.
