Rabbi Nathan Slifkin is widely known for his innovative work in the study of Judaism, lectures on the deep interaction of representatives of the animal kingdom and the Torah, as well as the study of the links between Judaism and the natural sciences. Noting the fact that the most important issues in classical Jewish literature are law and theology, the author draws attention to the mysterious creatures, fabulous monsters that are so often found in Scripture, the Talmud or midrash. Moreover, in each case, Slifkin wonders whether this is a mythical description of a real animal or an erroneous interpretation, and possibly a fabulous creation that never existed. Conducting his research from the point of view of theological interpretations, the author managed to stay within the framework of modern science, not focusing on the contradictions between the scientific and religious worldview.
