Sotheby's have an auction
coming up of Judaica. It includes several manuscripts. At least one is from the Montefiore collection. But one of the major items that they are touting is a medieval Spanish tittled
Torah scroll. The catalogue claims that it was written in the circle of R Shem Tov ibn Gaon
. The entry is quite long and interesting.
There are also several Esther scrolls. The most important one is from 1564, and is apparently the earliest decorated Megillah. It was written by a woman named Estellina bat Menahem. Yup, a female scribe
And two megillot illustrated by Shalom Italia.
Cool stuff. Catalogue is here
