Genius (literature)
The concept of genius, in literary theory and literary history, derives from the later 18th century, when it began to be distinguished from ingenium in a discussion of the genius loci, or "spirit of the place". It was a way of discussing essence, in that each place was supposed to have its own unique and immutable nature, but this essence was determinant, in that all persons of a place would be infused or inspired by that nature.
