Final answer:
In Duccio's 'Christ Entering Jerusalem', depth may be conveyed by centering Christ, utilizing architectural elements, and framing with gates. However, specific techniques Duccio used are not detailed in the provided information.
Step-by-step explanation:
In the painting 'Christ Entering Jerusalem' by Duccio, the artist conveys diagonal movement into depth through several techniques. While the correct technique isn't explicitly provided within the information given, we can infer from the principles of art history and composition that such movement is commonly achieved through methods like positioning the central figure, including detailed architectural elements, and framing the scene strategically.
For example, by placing Christ at the center of the composition and between two groups of people, the artist can create a sense of movement and depth as the eye is naturally drawn to the central figure. Detailed architectural elements, similar to those mentioned in the description of Masaccio's painting with its barrel vaults and coffered ceilings, can also guide the viewer's eye into the depth of the painting. Moreover, framing the crowd welcoming Christ with structural elements like a gate can reinforce the impression of spatial recession, much like the use of arches and vaults in Renaissance art to create a realistic illusion of space.
However, in the context of the detailed information provided about Renaissance paintings, Duccio's specific techniques for creating depth with diagonal movement are not covered. It appears that the answer to the student's question requires specific knowledge of Duccio's art, which is not included in the reference material.
