The contributors to this book analyze how the redactors of the Talmud transformed and reworked earlier aggadic (non-legal) traditions. Critical study of the Babylonian Talmud is founded on the distinction between two literary strata: traditions attributed to named sages (the Amoraim, c.200-450 CE) and setam hatalmud, the unattributed or anonymous material.
The conclusion of modern scholars is that the anonymous stratum postdates the Amoraic stratum and should be attributed to the Stammaim (c.450-700 CE.). The articles in the book demonstrate that the Stammaim made a profound contribution to the aggadic portions of the Babylonian Talmud.
