I didn't see any ancient literature or major literature about romantic love anywhere outside of western civilization.
Wikipedia definition of romance novel is:
The Romance Novel is a literary genre developed in Western culture, mainly in English-speaking countries. Novels in this genre place their primary focus on the relationship and romantic love between two people, and must have an "emotionally satisfying and optimistic ending."
Not in the bible. Not in any chinese fiction (we got tons of porn) Not in japanese, javanese.
Even in western civilization, the closest thing I see about romance is in the movie stealing heaven. Of course we have this romantic king Hendry that live till death do them part with 8 of his wives.
Is romantic love recent western invention?
In particulare, are there any romance story that's different from some rich possibly polygamist guy wanting some hot babe?
Sample of answer:
- Song of songs. Mate selection story between rich king Solomon and some hot babes.
- Some India stuffs. Mating selection story between some rich king and some young hot babes.
