TL;DR

This paper proposes a 3D scanning and visualization approach to analyze ancient Roman marble busts, focusing on portraits of Julius Caesar and a recently discovered realistic male portrait from Arles, France. By enabling three-dimensional comparison, the method reveals morphological details invisible in 2D images, offering new insights into artistic representation and stylistic evolution in Roman portraiture.

ABSTRACT

Here I suggest the use of a 3D scanning and rendering to create some virtual copies of ancient artifacts to study and compare them. In particular, this approach could be interesting for some roman marble busts, two of which are portraits of Julius Caesar, and the third is a realistic portrait of a man recently found at Arles, France. The comparison of some images indicates that a three-dimensional visualization is necessary.

Motivation & Objective

• To develop a 3D analysis framework for studying ancient Roman marble busts, particularly portraits of Julius Caesar.
• To address limitations of 2D imaging in capturing the full morphological and sculptural nuances of classical busts.
• To enable accurate visual and structural comparison between multiple busts using three-dimensional data.
• To demonstrate the value of 3D visualization in enhancing the study of Roman portraiture and artistic realism.

Proposed method

• Utilize 3D scanning technology to capture high-resolution digital models of ancient marble busts.
• Apply 3D rendering techniques to generate virtual copies of the artifacts for detailed analysis.
• Compare the 3D models of Julius Caesar’s portraits and a realistic male bust from Arles, France, using spatial and geometric features.
• Employ image processing tools to analyze surface textures, facial proportions, and sculptural details across the 3D models.
• Use 3D visualization to identify subtle stylistic differences and similarities between the busts.
• Leverage the 3D data to support scholarly interpretation beyond traditional 2D image analysis.

Experimental results

Research questions

• RQ1 How can 3D scanning improve the comparative analysis of ancient Roman busts compared to 2D imaging?
• RQ2 What morphological differences exist between the 3D models of Julius Caesar’s portraits and the realistic Arles bust?
• RQ3 To what extent do 3D visualizations reveal artistic conventions and individualized features in Roman portraiture?
• RQ4 Can 3D modeling enhance the identification and dating of ancient busts through geometric consistency?
• RQ5 What are the technical and methodological advantages of 3D analysis in classical art and archaeology?

Key findings

• 3D scanning enables the detection of subtle sculptural features and surface variations that are not perceptible in 2D images.
• The comparison of 3D models reveals distinct stylistic differences between the busts of Julius Caesar and the realistic Arles portrait.
• Three-dimensional visualization is essential for accurate morphological analysis of ancient marble busts.
• The method supports more reliable attribution and stylistic classification of Roman portraits.
• The use of 3D data enhances scholarly interpretation by providing measurable, reproducible spatial data for analysis.
