Theater and novel.

Here’s a revised version of your text with some adjustments for clarity and flow:

“A primary source of inspiration for prose theater, opera, musicals, and dance, due to the density of its plots, the complexity of its characters, and the stratification of its languages, the novel in Italy has often been reinterpreted by adapters, dramaturgs, and directors. These adaptations have led to performances that are either illustrative, celebratory, or, conversely, innovative. The key distinction lies in the authors’ ability to shuffle the cards, adapting the forms of literary tradition to their own personal artistic exploration.”
