House of Books, the Per Medjat
While official texts are still written in Middle Egyptian, literary texts are now written in Late Egyptian (in the New Kingdom).
We have many classics from the Middle Kingdom:
Tale of the Eloquent
of the Eloquent Peasant
Many have commented that tales from the New Kingdom seem to be lighter and more episodic.
