Surely not. Bacteria weren't part of the mindset of UK castle builders!?
I'd expect there right about making it lighter in the garderobe, and possibly over time it was noticed it made the room less smelly?
- pengaru 6y agoYou don't have to know the why to appreciate lime plasters stay clean/grow less mold in dank environments through experience.
- pbhjpbhj 6y agoDoesn't "because" say they knew why. If it just said "which" instead of because then I'd agree with you. Perhaps there was some mediaeval theory relating lime and pestilence?
- Jtsummers 6y agoA lot of things were done in h the past despite people not knowing why. The because should be read as a retrospective reason. The originators of the practice at have just found it dealt with odor and so they did it, in retrospect we can add the actual reason it helped.
- pengaru 6y agoI don't see a problem with the author using a more modern terminology for "cause" than would have existed at the time, to describe what anyone working with lime plasters appreciates on a basic level; the stuff stays exceptionally white and clean. Personally I don't like their saying just that it kills off bacteria. It's an antimicrobial/fungicide in general because of its elevated Ph. I'd prefer the article take the opportunity to educate me about the practical value of lime plaster than restrict itself to the limited education of medeivil minds.
- cgriswald 6y agoYou might not see the problem, but it's factually inaccurate because there is an attribution error. Oddly in this case where the author could have made a correct attribution he used the word "which" which does not ascribe a cause. If he had simply switched "which" and "because" we probably wouldn't be having this conversation, because the sentence wouldn't have been false. It makes me wonder if the author swapped around the rest of the sentence after writing it originally. I don't think anyone is suggesting reducing the information content. Even wanting more is just fine and dandy, but the proper way to do that would be to correctly attribute the reasoning of the time, and then add something along the lines of "which we know today does $x."
- xapata 6y agoEither way, I'm glad we can agree that it's important to be precise with words. Thanks for making my day a little brighter.
- dmurray 6y agoThe sentence is mangled and syntactically incorrect anyway - there's no other reason before the "and". Maybe it originally said "and kills off bacteria" before a "because" was added during the editing process.
- ThePowerOfFuet 6y agoThe other reason before the "and" was that it maximised light reflection (and hence ambient light levels in the room).
- dmurray 6y agoBut that reason is stuck in a descriptive clause modifying "lime-plaster" or "a coating of lime-plaster". You wouldn't write "Walls were sometimes whitewashed with a coating of lime-plaster which was white and because lime kills off bacteria." The longer sentence makes it less jarring until you try to parse it carefully, but still very poor style. I don't think I'm being some kind of prescripivist grammar Nazi here: the rest of the piece is written reasonably professionally and I'm sure the editors would fix that if they spotted it.
- svrb 6y agoI think even this gives too little credit in a way. Why were the walls whitewashed? To grow less mold and generally stay cleaner. That's the only why for doing the action, and it seems to have been perfectly well understood. The only thing the modern biochemical understanding does is tell us why this worked. At best this can help us find more effective methods, but it doesn't really add anything to the practice. Put another way, if you were put back in time, what would the most effective means of accomplishing this goal be? Probably the same lime whitewash actually used.
- burfog 6y agoI'd like to know why this isn't standard today. I don't like the typical moldy latex paint.
- throwaway0a5e 6y ago>I'd like to know why this isn't standard today. Get a quote for paint and extrapolate out to the effective hourly wage of the painter. That's why.
- coryrc 6y agoPaint is easy to clean; plaster is porous and will stain easily.
