It's a screenshot from a game so of course it's not accurate. But I wonder if houses in Middle Age were as dark as those in broad daylight? It looks really hard to see anything if far from light source.
Did they not have as many windows as we do now? If it were that dark, how can they do daily activities, e.g. reading, cooking, etc?
From Frances and Joseph Gies' Life in a Medieval Village:
"Interiors were lighted by a few windows, shuttered but unglazed, and by doors, often open during the daytime, through which children and animals wandered freely. Floors were of beaten earth covered with straw or rushes. In the center, a fire of wood or of peat, commonly used in Elton [case study village the book is based on; ruled by Ramsey Abbey, a monastery founded in 969], burned on a raised stone hearth, vented through a hole in the roof. Some hearths were crowned by hoods or funnels to channel the smoke to the makeshift chimney, which might be capped by a barrel with its ends knocked out. The atmosphere of the house was perpetually smoky from the fire burning all day as water, milk, or porridge simmered in pots on a trivet or in footed brass or iron kettles. At night a fire-cover, a large round ceramic lid with holes, could be put over the blaze."
The authors describe these houses as sharing "the common characteristic of impermanence," with cheap materials and poor construction work. Based on the description, at least for a 11th Century English cottage, I would definitely picture a dimly-lit, smoky room that would probably make reading difficult (not that peasants read; monasteries were the big centers of literacy in England during this period).
Well, it depends on where you're talking and when you're talking. The 'Middle Ages' span a huge amount of time.
As far as that screenshot goes, that seems pretty poorly thought out, honestly - there are no windows, and no ventilation. The smoke from all of those lamps would be so thick you couldn't see through it.
First off, windows were rare in medieval cottages and glass would have been available only to the very wealthy. Even then, panes would have been much smaller than what moderns are used to. As far as daily activities, most of a peasant's time would be spent working in the field, doing chores, etc. The majority of time would be spent outside the home. Also, no one would burn candles in the daytime. Nor would many people be able to read. What light could come in to cottages would have been provided by the fireplace (which is also where cooking would be done) and perhaps an open doorway. Also, animals would be in the home, especially during the winter. Imagine a cramped, smoky, smelly cottage with packed dirt floors and heat only coming from a fireplace. As far as the chapel you've included, that's a little darker than the ones I've been in. Windows were a really big deal in chapels.
