Clarification
I picked Athena as the goddess of literature because to her are attributed to some inventions of arts and literature. But researching I bump with the fact that there is no god to whom attribute the literature. But there were nine Muses, Greek goddesses of poetic inspiration. They were:
Klio (Historiography)
Melpomene (Tragedy)
Thalia (Comedy)
Euterpe (Poetry, Lyrics)
Erato (Love poetry)
Polyhymnia (Songwriting)
Kalliope (Epic, Rhetoric, Philosophy, Science)
I hope the answer and its clarifications help you
