Some of the Dead Sea Scrolls were hidden in jars which were later found in the excavation of Qumran. This type of pottery is unknown elsewhere: since it was found in the caves where the scrolls were hidden, and in the Qumran ruins, many believe it is conclusive proof that the scrolls were written in Qumran.
The Dead sea Scrolls. Between 1947 and 1956 Qumran has been the most important archaeological site of the world . In this period a collection of 972 ancient texts in 11 different caves has been found. The majority of them are made of parchment or papyrus, mainly written in Hebrew and Aramaic and few in Greek. http://paolo-deadseascrolls.blogspot.com/2011/06/final-report.html
On February 7th 1947, the Dead Sea Scrolls, which date from around 150 BC – AD 68, were discovered in some caves near the Jordan River. The 900 scrolls, which are made of leather and papyrus, make up three types of documents – texts from the Hebrew Bible, books from the Old Testament and documents including some poems and a book of community rules. They are considered of great religious and historical significance and are now kept in Jerusalem.
