Judah ben Barzillai (Albargeloni)[1] was a Catalan Talmudist of the end of the 11th and the beginning of the 12th century.
He came of a very distinguished family, on account of which he was not seldom called "ha-Nasi" (the prince), a title of honor borne also by his descendants in Barcelona.
From quotations found in works of more than forty authors it is seen that Judah codified the whole law, ritual and civil.
[4] The part of the codex which deals with marriage laws and kindred topics is called by some Seder Nashim; by others, Yiḥus She'er Bosar.
The author betrays an astonishing familiarity with the Talmudic-Midrashic literature, and gives extracts from works of the Geonim which are otherwise unknown.
Judah was acquainted with the philosophical writings of Saadia and of Samuel ben Hophni, but not with those of Solomon ibn Gabirol and Baḥya.
