We admit it, we are obsessed with blue. Also with seashells and snails. Our house is filled with skeins of blue threads, tufts of wool in every shade of blue imaginable, and dozens of shells of different sizes and peculiar shapes. But we weren’t always so infatuated.
We were introduced to the wonderful world of blue quite by chance. Late one Thursday night, around twenty years ago, an old high-school buddy called and asked if I would like to join him the next day to go scuba diving in the Mediterranean. He was going to help a dedicated rabbi collect some sea-snails. Not just any snails, but a particular species that had once been used to produce the fabulously expensive and stunning dye known as biblical blue, or tekhelet. In the ancient world, tekhelet had been a cornerstone commodity worth up to twenty times its weight in gold, but for centuries it had been lost and all but forgotten. Only recently had there been a revival of interest in the ancient dyeing process. I myself had only a faint knowledge of the topic of tekhelet, which is mentioned numerous times in the Bible as the main component of the priestly garments and the decorative curtains of the Temple.
The night my friend called was cold and wintery, and the next day was going to be the same or worse. Joining him would mean that I’d have to wake up before dawn in order to make it from my home in Jerusalem to the Northern coast and back before Shabbat. I had every reason to bow out, but words seemed to come out of my mouth before I could properly think them through: “Sure – see you at four.” Those words were the beginning of an adventure that would start as a curiosity, develop into a passion, and ultimately become the obsession that virtually defines my identity.
