I’ve only read Tolkien, H.P. Lovecraft, and maybe some Conan.
On my personal Appendix N:
Grahame, Kenneth. “The Wind in the Willows”
Heaney, Seamus translation “Beowulf“
Homer, “The Odyssey“
Peters, Ellis. Brother Cadfael mysteries, esp. “One Corpse Too Many”, “The Rose Rent”, “The Leper of St. Giles”, “St. Peter’s Fair“
Martin, George R. R. Martin, “Game of Thrones“
Shakespeare, William - “The Tempest”, “Henry V”,”Midsummer Night’s Dream“, “Romeo & Juliet”, “Richard III”, “Macbeth”, etc.
Twain, Mark - “Connecticut Yankee in King Arthur’s Court”
Lots of movies and series:
”Robin Hood” - Errol Flynn version
”13th Warrior“ - yes, I really like Beowulf
“The Black Shield of Falworth“ - so cheesy but I like it
”The Princess Bride”
”Conan the Barbarian”
”Cadfael“
”Silverado” - 2 of my players think it’s a D&D campaign and I see their point
”Game of Thrones” (first 5 seasons)
”Wheel of Time”
”The Witcher”
