That, in a nutshell, is the meaning of 'precession of the equinoxes'. And that is exactly what is involved in the notion of the 'dawning of the Age of Aquarius'. The famous line from the musical Hair refers to the fact that every year, for the last 2000 years or so, the sun has risen in Pisces on the vernal equinox. The age of Pisces, however, is now approaching its end and the vernal sun will soon pass out of the sector of the Fish and begin to rise against the new background of Aquarius.
