Another famous contemporary of Qimḥi was Jacob ibn Meïr, called Rabbeinu Tam, of Ramerupt, who was the greatest Talmudic authority of the day. This scholar, wishing to settle the literary quarrel between the followers of Menahem ben Saruq and of Dunash ben Labraṭ, had written a book of decisions ( "hakhraʻot"), in which he took the part of Menahem. These decisions did not satisfy Qimḥi. Feeling himself better able than Rabbeinu Tam to pass judgment in the case, he wrote the "Sefer ha-Galui" in 1165.
