Maybe this is common knowledge, but I recently stumbled across "The Great Courses" on Amazon Video. There is a free 7 day trial, and the content I have viewed so far is pretty top notch. I'm not an Amazon shill, and subscriptions are available via
https://www.thegreatcourses.com, I just figured this would be the fastest option for many.
So far I have been watching Arthurian Myth and Legend and the other history classes, and they are excellent. Let me know if you have any recommendations!
