What is the Shamir?

The stories in the Babylonian Talmud tell the tale of the “shamir,” which can disintegrate almost any substance with its gaze. In most interpretations of this legend, the shamir is a worm-like creature (see: Shamir on page 221). However, in some versions, the shamir is a greenish stone-like substance, which has the same powers. This module includes both versions of the tale, with the Shamir reflecting the legends of the creature, and the Staff of the Shamir reflecting the version of the stone.
