Final answer:
In "Entry into Jerusalem" by Duccio, the composition is characterized by its horizontal layout, dividing the painting into three horizontal sections, which is a key feature.
Step-by-step explanation:
In "Entry into Jerusalem" by Duccio, the unique feature of the composition is its division into three horizontal sections. This horizontal orientation allows the painting to show a dense crowd of figures in the top section, creating a sense of multitude while maintaining the individuality of each figure. Unlike Baroque art, which commonly utilizes diagonal lines to depict movement and a caught moment in time, Duccio's work here focuses on a more stable and grounded approach. It is important to note that during the period in which Duccio worked, city-states like Siena fostered their own unique styles distinct from places like Florence. Duccio's work reflected the Sienese style, known for its decorative surfaces and sinuous lines.
