In this novel and innovative work, Rabbi Dr Edward Reichman traces the medical understanding of anatomy, physiology, and therapeutics across time and genres of rabbinic literature. The accumulated literature of centuries of Jewish legal discourse on medical topics serves as the foundation for contemporary Jewish bioethics. As these writings span the chronological gamut of scientific and medical discovery, it is essential to view each source in its proper historical context. Marshaling a vast array of sources from multiple disciplines, Reichman demonstrates the importance of the historical dimension not only for medical halakhic research but to better understand the unique relationship of Judaism and medicine throughout the centuries.
