ABRAHAM BEN JOSIAH HA-ROFE:
A Karaitic scholar and physician, born in Troki, a town near Wilna, in Lithuania, about 1636; died there in 1688. He was one of the leading scholars of his time, and, according to Karaitic tradition, a disciple of Joseph Solomon Delmedigo. In his later years he was appointed physician in ordinary to King John Sobieski (1674-96). He wrote a number of works on medicine and natural science, which, however, were never printed.
