To determine the answer to this question, we need to look at the purpose and historical usage of illuminated letters. Illuminated letters were highly decorated initials found at the beginning of a text or paragraph, characterized by intricate designs, illustrations, and vibrant colors.

Now, let's consider each option:

a. Mythical texts: Illuminated letters were occasionally used to illustrate mythical texts, but they were not the most common type of text to be adorned with such artistic letters.
