When the zodiacal signs were engraved on gems to give them special virtues and render them of greater efficacy for those born under a given sign, the Hebrew characters designating the sign (or at least the initial character) were often cut upon the gem. As the letters in which the earliest of our sacred writings were written, a peculiar sanctity was often ascribed to these Hebrew characters, which were perhaps the more highly valued that they were unknown to the owners of the gems, and hence possessed a certain air of mystery for them. The subjoined list of the signs with the Hebrew equivalents may be of interest on this account.
