Why does the Sana'a manuscript have two layers of text?

discovered these things pulled them out they've realized a certain amount of them um there's varying there's there's quite a few pages but there's different things but in some they've said that they've realized this is the Quran okay or page it's not the complete Quran uh some people say it's pretty much a lot of Surah Toba there some people have said I think they they may be up to uh something like I think 80 Pages or something like this worth by the way these are not Pages like these kind of pages these are parchments so things like ancient um um initially cloth like cloth but it's actually taken from

animal hide so animal skin that was used to write on so that was one method that people used to write on so they found a lot of these and then anyway to cut all that story short they you know they called in some experts and the experts thought well you know this sounds interesting so they they put all all this stuff on microfilm and then then there was all this long legal battle going on with the yemeni government but anyway I think in the '90s the the German experts were allowed to release those uh uh the these microfilms or whatever it was um and they started to research these manuscripts now these

manuscripts had a like I said uh verses of the Quran on them which is nothing so surprising but what when it got interesting was that they realized that these this writing these verses of the Quran um they had like an like an a like a shadow effect underneath them so it appeared that beneath them there seems to have been something written before that was obviously then wiped clean and then Rewritten so the writing they have on there is is not the the earliest

writing on that parchment okay and this once again is nothing new so in the past like in uh ancient Arabia because writing was not big anyway and the was no such thing as paper uh what people would do is write on these parchments write on animal skin and because uh if they needed to rewrite something or what they would often do is wash it clean or wipe it clean and write on it again so this is common practice I mean it's nothing so unusual up until this point then what happens is using the latest technological equipment they've managed to kind of extract the under

text so the lower text has managed to be so they've used using computer visualization they've got it they've had managed to extract it using um um using certain lighting techniques and things like this I think they've used like ultraviolet rays and things like this but they've managed to extract the lower text so the lower text is also appears to be the Quran right now so that so okay so up until here that's seems okay it gets a bit more interesting that the lower text

of the Quran seems to be different to uh the current understanding of the Quran in some ways so this has become known as the manuscript and they also call it a um a pal oh bloody hell a palest right I believe palest is what it's called as well Rob so that's a document that is I call I say document but a parchment that has
