His commentary on tractate
Kiddushin was published in Vlina editions of the
Talmud Bavli mistitled
Tosafos Ri HaZaken, an error noted by the editors of the
Vilna Edition Shas, who prove that the commentary could not have been written by the
Ri Hazaken. Rabbi Abraham's commentaries to tractates
Yevamos,
Nedarim,
Nazir,
Rosh HaShannah,
Yoma, and
Sukkah have been published in recent years. Additionally his commentary on
Chullin is currently under production. His commentaries on
Chullin and
Kesubos are quoted by
Jacob ben Moses of Bagnols, who wrote between 1357 and 1361, and by
Menachem di Lonzano, who lived in the second half of the sixteenth century. He has been mistaken for the father of the celebrated anti-Maimonist
Solomon ben Abraham of Montpellier, who flourished in the middle of the thirteenth century.
Isaac de Lattes, in his "Sha'are Zion" (ed. Buber, p. 42), names Rabbi Abraham among the scholars of the generation succeeding Solomon, of whose father he speaks simply as "Abraham", without the title of rabbi. ==References==
