Final answer:
The mosaics and gilded artworks within Hagia Sophia, such as the tympana mosaics and those depicting religious figures and emperors, are examples of architectural details that do not serve a structural purpose but rather add historical and religious significance to the building.
Step-by-step explanation:
Among the splendorous and historical architectural details of Hagia Sophia, not all serve a structural function. The building, an architectural marvel known for its domes and archways, is also replete with symbolic and decorative elements that highlight its historical and cultural significance. The mosaics present within Hagia Sophia, such as the tympana mosaics, and the lavish use of gold in the tenth-century mosaic of Mary, the child Jesus, and emperors Justinian and Constantine, serve as prime examples of details that are not structural but rather are infused with historical and religious symbolism. In particular, the mosaics featuring Greek Christian iconography, halos signifying holiness, and the images of emperors and empresses, act as a reminder of the intertwined nature of the Church and state in the Byzantine Empire. Therefore, these mosaics and gilded artworks, which do not contribute to the physical support or integrity of the building, are the types of architectural details in Hagia Sophia that do not serve a structural purpose.
