This book is about ways in which the land of Israel, the homeland of the most paradigmatic of all diasporas, was envisioned in late antiquity and the early Middle Ages in the literature of the sages. It is about the Land according to the redefined Judaism that emerged in the centuries following the destruction of the Jerusalem Temple in 70 CE. This Judaism replaced the temple cult with Torah study - a study that pertained in part to that very temple cult, that became a portable homeland, and that reconfigured the Land.
