Barbara Tuchman's "a distant mirror" looked at the in-betweeners, the middle class guys of the 1300s.

She has a long intro where she said she wanted to cover more mundane life of peasants, but there was a dearth of source material written, since that population was largely illiterate.

I imagine it'd be like if someone in the year 3000 wanted to know what kind of airplanes the average peasant had in 2022. Or what kind of selfie camera junior high kids had in the 1970s. The technology just hadn't l worked it's way that far into society yet. Same with writing in the pre-guttenberg era. And the people who could afford a scribe, well, they prolly weren't writing about the farrier and the farmer, or the butcher and the baker. She also made a point that very little was written about women, either.

Anyway, good luck in your search
