...kurszán...kündü a napos...

As you read in that Persian book, it talks about Kurz near Saklab, a people named Kurzi or Kurzian have been also mentioned in the Persian books, they could be the same Curonians: http://en.wikipedia.org/wiki/Curonians as you read it says they were called Kurs and their land Kurzeme, anyway the book says that in the east of it are the Rus and Volga Bulgaria, that seems to be true about modern Latvia.   The book also says about Saklab: " اين ناحيتي است بزرگ و اندر وي درختان سخت بسيار است " it means "that is a large region and there is deep forests", "و ايشان اندر ميان درختان نشسته اند" "and people of this region live among the trees", I have asked some questions in another thread:  When the author of the book says the title of the kings of Saklab is "Svit", does he mean "Sviat" like in Sviatoslav? "Svit" is similar to "Swede", could it be related to Swedes? Is it also true that their daily diet was "milk" (طعام ملوک ايشان شير است)? Their palaces were underground in the winter (همه بزمستانها اندر کازه ها و زيرزمينها باشند)? There were a large number of forts and citadels (ايشان را قلعه ها و حصارهاي بسيار است)? People wore mostly linen clothes (جامه ايشان بيشتر کتان است)? (The Persian word for linen is Katan, similar to cotton),

They were all fire-worshippers (همه آتش پرستند)? ....
