How did the Age of Aquarius enter popular culture?
The Age of Aquarius in the U.S. is associated with the hippies of the 1960s and ’70s, and now with the New Age movement. In both cases, the arrival of the Aquarian age has been associated with … well, harmony and understanding, sympathy and trust abounding. And that brings us to the 1967 smash-hit musical Hair, with its opening song Aquarius, by a musical group called the 5th Dimension.
The song opened with the lines:
When the moon is in the Seventh House
And Jupiter aligns with Mars
Then peace will guide the planets
And love will steer the stars
This is the dawning of the Age of Aquarius
It’s hard to describe how Hair, which seems daring even today, affected people when it opened on Broadway in 1968. It subsequently ran for 1,750 performances on Broadway and 1,997 performances in London, with simultaneous productions in cities across the United States and Europe, and with accompanying recordings (the original Broadway cast recording sold three million copies). Almost single-handedly in the late 1960s and early 1970s, this Broadway musical brought the Aquarian Age concept into the popular culture. The video below isn’t the original, but you’ll get the idea.
Bottom line: The Age of Aquarius is an astrological age, which shifts roughly every 2,150 years. It’s defined by the sun’s position at the time of the March, or vernal, equinox.
The Age of Aquarius begins when the March equinox point moves out of the constellation Pisces and into the constellation Aquarius. But there’s no definitive answer as to when that will be. This post explores some of the possibilities.
