I learned that Borges is a famous Spanish writer and poet, and his works are famous for their profound thoughts and beautiful language. However, I'm not sure what you mean about the ceiling of "mourning" romance.
If you are referring to whether there are elements of "mourning" romance in Borges's works, then I think this requires a more specific discussion. Because the themes of Borges's works are very wide, including philosophy, religion, history, human nature, etc., and the styles of his works are also diverse, from poetry to novels, from short stories to novels. Therefore, more specific information or context is needed to answer this question.
In short, no matter what you are referring to, I suggest that you can learn more about Borges's works and style to better understand his literary characteristics and artistic value.
