I have no idea why this etch – #429 – is named “Zodiac”.  It doesn’t appear to have any of the commonly known signs of the zodiac – no lions, archers or water bearers, etc.

I don’t consider it to be pretty, but it is of course interesting. According to Ream, Bredehoft and Bredehoft in Encyclopedia of Heisey Glassware: volume one, this plate etch was introduced circa 1919 and discontinued by 1928.
