 Flusser also took the view (1992) that the "Birkat haMinim" was originally in reference to Sadducees, not Judaeo-Christians.Flusser was trained as a philologist and thus the study of Greek, Latin, Hebrew, and Aramaic manuscripts was central to his research interests.He was primarily interested in the medieval Book of Yosippon which claimed much of his time from 1940-1982 when he finished his edition of this medieval history of the Second Temple period.
