Cornelia Funke's fantasy series beginning with the novel Inkheart features a character named Fenoglio, an old man who wrote a fantasy novel called Inkheart.
Was Fenoglio based on, or inspired by, any real fantasy author(s)?
Since this is an issue where, if the answer is yes, Funke might not necessarily admit it (for obvious reasons), I would accept answers based on either "canon" evidence such as author interviews or (for me more interesting) a solid evidence-based analysis connecting Fenoglio with a real author.
