I...believe so, yes. Astronomically speaking, that is the group of twelve constellations along Earth's ecliptic, yes? And I believe...it is also a method of divination is memory serves? Something to do with a belief that the position of the stars and planets have an effect a person's personality depending upon the time of their birth? [He sounds...rather skeptical about that particular aspect.]

Or am I perhaps misremembering? A friend from Earth explained it to me once so I'm afraid that's all I have to go by, really.
