Regarding the second one, variations of that, to help or protect strangers/travellers, seems to have been relatively common across a variety of historical cultures.

Tangentially, it also reminds me of a woman's grave that was found in Denmark I think. I can't remember how old the grave was, but something like 3-4000 years. They were able to use isotope analysis of her teeth, hair, stomach contents, etc. to trace her movements.

She was from the area, but in the last year of her life, she'd travelled down to around Switzerland and back. There was a documentary about it, I'll see if I can find it...
