Final answer:
The assertion that the Ascension from the Rabbula Gospels is an illumination rather than an illustration is supported by the use of gold leaf, a lack of narrative scenes, and symbolic iconography.
Step-by-step explanation:
The assertion that the Ascension from the Rabbula Gospels is an illumination rather than an illustration is validated by several factors:
- Use of gold leaf: The incorporation of gold leaf in the artwork is a characteristic of illuminated manuscripts, symbolizing the divine nature and spiritual significance of the subject matter.
- Lack of narrative scenes: Unlike traditional illustrations that depict specific events or stories, the Ascension does not have a sequential narrative, but rather focuses on the representation of a symbolic event.
- Symbolic iconography: The Ascension employs symbolic iconography, such as the mandorla of light surrounding Jesus and the angels carrying him to heaven, which is a characteristic feature of illuminated manuscripts.
