There are lots of books on these very topics. They range from the scholarly to the fluffy, but there are plenty of them. They of course are not aimed at the fantasy writer, but in some ways that's an advantage, as you can find the most surprising things in them. Just looking at my own shelves I see these: Daily Life in the Age of Charlemagne by Pierre Riche Everyday Life of Medieval Travellers by Marjorie Rowling Life and Leisure in Ancient Rome by J.P.V.D Balsdon Elizabeth's London, by Liza Picard The Stuart Age, by A.F Scott And literally hundreds more. "La vie quotidienne" has fascinated scholars and popular writers alike for generations now. In fact, some of the older ones (pre WWII and especially pre WWI) often have wonderful stuff precisely because their history is a bit shaky.
