The fire didn't entirely go out for centuries for everyone after Rome (if you wanna call that 'fire'). One example is Isadore of Seville's Etymologiae [0], a compilation of information from hundreds of classic sources he worked on from 600-625. 20 books, quoting over 400 authors. It grew so popular and was copied so often that about a thousand copies still survive.
And it wasn't 'dark' everywhere; the 'Islamic Golden Age' lasted from about 750-1250.
