Know any big, old, not very understandable books like dante's inferno?

i want to read more books like dante's inferno or the odyssey, the the da vinci code, hunchback of notre dame, or something along those lines. basically just books that tell a story that would have happened a long time ago, and have that ancient english, with a fantasy kind of world. and i know there was like some sort of sequel to the odyssey, but i forgot the name. if you could help out with that too? thanks!
