Socrates and Aesop's Fables

In Plato's Phaedo 

Socrates had a dream to write poems (verse).

After his trial, as
he was awaiting death, 

Socrates said, 

"[...] I realized that a poet, if he is to be a poet,

must compose fables, not arguments.

Being no teller of fables myself, I took the stories I knew

and had at hand, the fables of Aesop, and I versified the 

first ones I came across" 61b.
