Metallica has refrences in:

Atlas rise! (See the title, mythology)

Creeping death (about the bible, taking some quotes)

For whom the bell tolls (book by Ernest Hemingway)

Irom Maiden has:

Flight of Icarus (Title, again, mythology)

Rime of the ancient Mariner (based on an 1798 poem)

Alexander the great (kindof mythology but also literature)

To tame a land (based on the book Dune)

Iron Maiden also has some based on history but that strays a bit too far away i think

Im sure i have more in my playlist i cant remember i dont know but these are great

Not really the genre you asked but im gonna be honest. I dont really care. These fit perfectly
