What is a key influence in the development of the Carolingian script?

The development of the Carolingian script was significantly influenced by several writing traditions, making the choice of "all of the above" the most accurate. Roman cursive traditions played a crucial role as they provided a foundation from which the Carolingian script evolved. These cursive styles were more streamlined and helpful for quick writing, a characteristic that would be integrated into the formalized script of the Carolingian period.

Additionally, the influence of Greek minuscule letters is noteworthy, as they contributed to the elegance and readability of the Carolingian script. The Carolingian period sought to promote clarity and standardization in writing, making the finer features of Greek minuscule beneficial.

Celtic illuminated manuscripts also had a part in shaping Carolingian aesthetics, especially in their artistic qualities and elaborate lettering, thus contributing to the visual appeal of the script.

By pulling from all these various influences, the Carolingian script became a significant advancement in the history of writing during the Carolingian Renaissance, aiming for clarity, legibility, and beauty. This combination of influences resulted in a script that was both functional for administrative purposes and visually appealing for religious and literary texts.
