Some youtube resources that I reference or which inspired directions of research in this game. I’m lumping them all into one page, as I have only a little to say on each. In no order:
Gavin the Medievalist
A recent youtuber with a PhD in medieval literature - discussing old legends/histories in their poetry/prose and the reception and understanding of them. So far has mostly focused on adjacent topics like Beowulf and other Old English heroic-age stories (though will likely also cover even more relevant pieces in Arthurian legend eventually).
Ludohistory
A historian with a focus on history in games. Particularly influential would be his playthrough and discussion of Pentiment (positive) and similarly of Assassin’s Creed Valhalla (negative - or I should say pointing out ways stereotyped understandings of the time can mislead - which is not necessarily bad artistic decisions of course).
Cambrian Chronicles
Many niche topics - all broadly Welsh focused and mostly ancient and medieval. Most relevantly King Arthur: What Everybody Gets Wrong but there’s also intriguing deep dives into old legends, odd miscellanea and historicism.
Premodernist
An occasional historical essayist. Most notable in this context is probably the most famous video: Advice for time traveling to medieval Europe (and followup)
Overly Sarcastic Productions
Specifically, the summaries of the legends of King Arthur and Arthur’s Knights - these are fun summaries. There are some mistakes or simplifications, but it’s a neat way to get up to a moderate understanding of the canon.
Farya Faraji
Historical music (both reconstructed pieces and new music using researched and carefully selected composition/instrumentation/lyrics from the past), and a few well placed rants of orientalist and other misrepresentations in popular stereotypes of historical music.
Most is out of the timeframe or region.
Jackson Crawford
Primarily discusses Old Norse language and legends (also some Gothic and Old English topics adjacent to it, which can tie into it). For a pretty archetypical example, a discussion on Norse deities.
