Apuleius

I have been writing a ballad on the death of Philemon, as told by Suidas and Apuleius.'

Neither Fronto nor Apuleius was a man of great inventive genius.

But your friend Apuleius cultivates all these branches of art together and worships all nine Muses with equal zeal.

It is not an invention of Apuleius, but he inserted it in his novel, and thus preserved it to later times.
