Dulcea of Worms came from the elite leadership class of medieval German Jewry. She was the daughter of a cantor and the wife of a major rabbinic figure, Rabbi Eleazar ben Judah of Worms (1165–1230), also known as the Roke’ah (the Perfumer), after the title of one of his most famous works (Sefer ha-Roke’ah). Dulcea and her husband were members of a small pietistic circle of Jews, the Hasidei Ashkenaz, that developed following the devastations of the First Crusade of 1096. The documents of this movement include many mystical works, as well as a volume reflecting their ethical concerns, Sefer Hasidim (The Book of the Pious), an important historical source for everyday Jewish life in medieval Ashkenaz. R. Eleazar ben Judah may have written some of the passages in Sefer Hasidim, and could have been its editor.
