An Israeli-British study examined a group of 2,000-year-old tefillin cases found in the desert caves at Qumran, where the Dead Sea Scrolls were discovered, and determined that no dye at all was used in their construction, meaning they would have had their natural leather color. According to a discussion in the Gemara, a foundational Jewish legal text redacted and compiled circa 500 CE, the straps of the tefillin were required to be black, but there was a debate over whether the boxes themselves were also obligated to be black under this ruling. 4 In examining the ancient phylacteries, the researchers used a series of modern methodologies, including multispectral imaging, Raman spectroscopy (a non-destructive chemical analysis technique), ATR-FTIR spectroscopy and SEM/EDX (scanning electron microscopy with energy dispersive X-ray spectroscopy). “In the dark fragments we examined, the color appears to be the result of natural leather aging rather than intentional dyeing… In the past, we have found that some of the Dead Sea Scrolls have also undergone a similar process, which unfortunately has caused the parchment to darken,” explained Dr. Due to the findings, it’s likely that the practice of coloring tefillin cases a dark black color was “a later tradition” which “may not have been in place in the Second Temple period when the ancient tefillin examined i
