The Shamir and Ancient Knowledge of Radiation: A Fascinating Torah Perspective

Radiation, as is well known, is a natural phenomenon — like electricity and other forces of nature, whose extraction and use were only discovered in recent generations and are considered among the great achievements of the modern era. It is therefore striking to discover that the sages of the Torah, who lived nearly three thousand years ago around the time of the First Temple, were already familiar, through the Torah, with the possibility of delicate cutting and precise splitting through a form of radiation. This knowledge was part of the “secrets of nature” revealed by the Creator to the people of Israel when it was necessary for the fulfillment of certain commandments.

The Shamir: A Direct Natural Force

If those sages were living today, it is quite possible they would view modern scientists as using indirect and artificial methods to harness radiation from nature. After all, they were familiar with the most direct and original form of this force — the shamir worm.

Building the Temple Without Iron

To understand the following sources, it is important to note that the sages needed knowledge of this natural force in order to cut the stones used for building the Temple without using iron tools, as the verse states: “And the house, when it was being built… no hammer or axe or any iron tool was heard in the house while it was being built” (Kings I, 6:7).

Earlier Use in the Time of Moses

This knowledge was also used earlier, during the time of Moses and the generation of the wilderness — about four hundred years before the Temple was built, for engraving the names of the tribes onto the precious stones of the ephod and the breastplate worn by the High Priest.

In the book of Ecclesiastes (2:8), King Solomon describes using “spirits” (according to one interpretation). The Talmud (Gittin 68a) explains that Solomon used them to locate the hidden place of the shamir. The Talmud relates that Solomon asked the sages how he could build the Temple without iron tools, and they told him about the shamir, which Moses had already used.

How the Shamir Worked

The shamir did not cut by means of a physical blade or sharp edge. Rather, its cutting power came from a form of radiation emitted from it. As explained in the Talmud (Sotah 48b), the stones were not engraved with ink or cut with a chisel, because they had to remain whole and complete. Instead, the letters were marked as a guide, and the shamir was placed nearby. The stones would then split on their own — like a fig that cracks open in the summer without losing any of its substance.

In other words, there was no need for the shamir to physically touch the stone. It was positioned opposite the desired area, and the engraving was carried out through the radiation that emanated from it.

We conclude with another fascinating detail. Modern science has discovered that radioactive radiation and laser beams cannot be fully contained within most materials, as they pass through them. However, one material stands out as an exception — lead, which can block radiation.

How the Shamir Was Preserved

How, then, was the shamir stored? The sages describe it as follows: “After the destruction of the Temple, the shamir ceased to exist. What was the nature of the shamir? It was a creature created at the time of Creation. When placed upon stones or beams, they would split before it like the pages of a book. Even iron would split before it, and nothing could withstand it. How was it preserved? They wrapped it in wool and placed it inside a lead container filled with barley bran.”

Here we have yet another fascinating example of ancient knowledge of a rare natural phenomenon, revealed according to this tradition, by the Creator to the people of Israel for the purpose of fulfilling specific commandments.
