Evidence of a correspondence between the Prediluvian Patriarchs and the signs of the Zodiac is found in the Jewish synagogue inscription from Engedi (below).
The synagogue itself was destroyed around AD 530 so this inscription dates some time from the early Byzantine period. It lists the Prediluvian Patriarchs first from Adam to Japheth in two rows, then immediately following the names of the signs of the Zodiac in two rows, then the names of the Hebrew months. Thus:
1. Adam, Seth, Enosh, Kenan, Mahalalel, Jared,|
2. Enoch, Methuselah, Lamech, Noah, Shem, Ham and Japheth,|
3. Aries, Taurus, Gemini, Cancer, Leo, Virgo,|
4. Libra, Scorpio, Sagittarius, Capricorn, and Aquarius, Pisces.|
5. Nisan, Iyar, Sivan, Tammuz, Av, Elul,|
6. Tishrei, Marheshvan, Kislev, Tevet, Shevat|
7. And Adar.
The three final Zodiac names are written in a curious way thus: gdy wdly dgym i.e. literally “Capricorn AND Aquarius Pisces”. Considering that these correspond positionally to Noah AND Shem, Ham-and-Japheth (the last two corresponding to the two linked fishes of Pisces), the odd phraseology is understandable.
