Date, Attribution and the Scholarly Debate

Talmudic tradition associates the Tosefta with Rabbi Hiyya and Rabbi Oshaiah, students of Judah ha-Nasi active in the early third century CE, whose collections of baraitot were considered reliable enough that the Babylonian Talmud treats a baraita not taught in their academies with suspicion. On that traditional accounting the Tosefta took shape within a generation or two of the Mishnah itself, in the Land of Israel, before the amoraic period was far advanced.

Modern scholarship broadly accepts a third century Palestinian core while debating the date of final redaction, with positions ranging from shortly after the Mishnah to late antiquity. A livelier debate concerns direction of dependence. The long-standing view reads the Tosefta as a supplement composed around the finished Mishnah, but some scholars have argued that in a number of passages the Tosefta preserves the earlier form of a tradition, which the Mishnah's redactor then compressed, so that the supplement is at points older than the work it supplements. The question matters because it bears on how the Mishnah was made: whether its redactor abbreviated fuller sources that the Tosefta still shows us, or later teachers expanded the Mishnah's spare clauses. Either way the Tosefta remains the largest surviving body of tannaitic teaching outside the Mishnah.
