"Gemini Security Systems" burglar alarm, Liverpool • Apart from the name, this is supremely boring – it could at least have included a picture of some twins. Astronomically, Gemini is one of the oldest-named
constellations, dating far back into the Bronze Age and called "The Great Twins" by the Babylonians. To the Greeks they were the talented horsemen
Castor and Pollux, who despite being twin brothers had different dads, meaning only Pollux was immortal; when Castor died, Zeus allowed him to share Pollux's immortality, bonding them together in heaven as the constellation the Romans called Gemini.
Astrologically, it's the versatile third sign of the zodiac, ruled by fleet-footed messenger god
Mercury. Gemini types are meant to be lively, inquisitive, communicative, inconsistent, and a bit unreliable – not all of which are useful traits for security firms. My theory for why Gemini is one of the few signs represented on burglar alarms, and a popular business name in general, is that Geminis are inordinately proud of their dual-natured and slightly annoying star sign
characteristics. And, to prove my point, there will be another one along tomorrow...
