The remarkable story of Biblical tekhelet, the wildly popular and precious blue dye worn by the Kohen Gadol and affixed to the tzitztit of the common Jew in antiquity, and lost to the world nearly 1,300 years ago. The exciting tale of its rediscovery seamlessly weaves together Torah and science, scholarly research and adventure, and a host of larger than life personalities, culminating in the revival of the ancient mitzvah of Tekhelet on tzitzit.
