Israel — One of the mysteries that scholars have puzzled over for centuries is the exact shade of blue represented by “tekhelet,” which the Bible mentions as the color of ceremonial robes donned by high priests and ritual prayer tassels worn by the common Israelite.
The New York Times continues:
What was known about tekhelet (pronounced t-CHELL-et) was that the Talmud said it was produced from the secretion of the sea snail, which is still found on Israeli beaches.
Traditional interpretations have characterized tekhelet as a pure blue, symbolic of the heavens so that Jews would remember God. Not so, according to an Israeli scholar who has a new analysis: tekhelet appears to have been closer to a bluish purple.
The scholar, Zvi C. Koren, a professor specializing in the analytical chemistry of ancient colorants, says he has identified the first known physical sample of tekhelet in a tiny, 2,000-year-old patch of dyed fabric recovered from Masada, King Herod’s Judean Desert fortress, later the site of a mass suicide by Jewish zealots after a long standoff against the Romans.
“It really is majestic,” Dr. Koren said of the shade, which he said remained close to its original hue and appeared to be indigo.
Blue in a textile sample taken from Masada
Until now, the limited number of blue or purple dyes found on textiles from the period in this region have been derived from plant material, he said.
The fabric he examined was one of many items discovered at Masada in the 1960s and stored at Hebrew University in Jerusalem. It came to his attention when a British historian, Hero Granger-Taylor, who specializes in ancient weaves, asked him to analyze some textiles. Dr. Koren said he was the first researcher to make the connection between the fabric and the snail dye.
He found that the dye used in the Masada sample, a piece of bluish-purple yarn embroidery, came from a breed of Murex trunculus snail familiar to modern Israelis. Such shades on textiles are rare finds since they were typically worn exclusively by royalty or nobility.
Determining what exactly tekhelet would have looked like in its day has been the subject of conjecture and curiosity among rabbis, religious commentators and scientists for centuries; it is considered the most important of the three ritual colors cited in the Bible. The other two are argaman, a reddish purple, and shani, known as scarlet…
