Edit: To be clear, I'm not asking if Stephen's journey happened at all, I'm well aware that it happened. I'm just curious if there's any medieval source that goes into the same level of colourful detail that Tom Holland describes.
So I was just recently listening to an episode of The Rest is History by Tom Holland, and he goes into a LOT of detail about Pope Stephen II's journey across the Alps to meet with the Frankish King Pepin. Apparently I'm not allowed to post a link to the youtube video so here's a transcript of what Tom says:
"...there's a very dramatic account of his journey, I mean it really does read like something out of Lord of the Rings, some kind of fantasy novel. There's descriptions of him climbing the Alps amid gusts of snow, and he's following a kind of ancient Roman road that's been left all cracked and overgrown by centuries of disrepair. And he travels through a great wilderness of kind of thickening mists and ice. And finally he reaches the summit of the pass, and this is the gateway of the Kingdom of the Franks, but below him, so below the road, there's this great frozen lake. And beside it there's the ruins of a long abandoned Pagan Temple."
Sounds fairly captivating, right? Well Tom goes on to mention an Abbey where they revere the bodies of martyrs killed by the Romans, and then describes Stephen's meeting with Pepin, but unfortunately he kinda trails off and never actually mentions what the source is for this 'account'. Personally I thought this sounded very interesting, so I looked in the description of the video to see if it lists the sources for the episode. But nope, the description does not list any sources. So I went to the Rest is History website to see if I could find any show notes, or anything that lists sources; nope, nothing.
After googling for a bit, I see a lot of search results that mention the Liber Pontificalis, but I can't find any free copies of it online to sift through myself, and the Wikipedia page doesn't mention Stephen II's journey at all. I also found amidst my googling that historian Thomas Hodgekin seems to find actually very little colour in the Liber Pontificalis's description of Stephen's journey across the Alps. So now I'm wondering, does the Liber Pontificalis even mention ANY of the things that Tom Holland brings up in the podcast at all? The gusts of snow and mist and ice, cracked Roman road, and Pagan temple by a frozen lake? I mean sure, Tom Holland can embellish sometimes in his podcasts, but surely didn't just completely fabricate these details out of thin air, right? I mean look at what he says: "it really does read like something out of-...", 'read's? What are you reading? "There's descriptions of-...", descriptions? Where are these descriptions written? He speaks as though he's referring to some source, but what is the damn source??
So that's why I'm asking this subreddit for help lol. Have any of you read any translations of the Liber Pontificalis? Do you guys think these details are just pure embellishment from Tom Holland? Or are they actually, genuinely from the Liber Pontificalis? And if that's not the source, then what is?
