The Tur is discussing whether we have to mention 9 be-av in all the tefillot or just during minchah. The Tur quotes an opinion of R. Yehudah Albartzeloni [al-Barcelona?]. Who is he? I don't remember coming across that name yet in any of the Tur simanim to date.

The Encyclopedia legedoli yisroel" has a write up about him (I can scan it if you do not have it).

In th seder hadors he is [mentioned] under the year 4830, apparently he is quoted in tosofs a couple of times (berocos 17b and eruvin 104) .

Thanks. I dug up this on the Internet:

and this from the EJ:
JUDAH BEN BARZILLAI ("ha-Nasi") , AL-BARGELONI (late 11th and early 12th century), rabbi of Barcelona. Nahmanides claimed descent from him, referring to him as "zekeni" ("my ancestor"). According to one statement (responsa, Tashbez, 1:15), he was a pupil of R. Isaac b. Reuben of Barcelona, but this is not substantiated from any other source and is open to question. The assumption that Abraham b. Isaac of Narbonne was his pupil is unfounded, even though Abraham constantly refers to his teachings. He was a contemporary of Abraham b. Hiyya, with whom he engaged in an interesting controversy on the question of postponing a wedding date for astrological reasons. Judah was strongly opposed, since he regarded it as contrary to Jewish law. Judah's works consist mostly of codes which were highly regarded in their time, but most of them were subsequently lost. Quotations from them by other authors show that they embraced all the halakhah which applied in practice.

here is the article from the Encyclopedia legedoli yisroel on R. Yehudah Albartzeloni
