It's also probably a reference to Ophiucus, the serpent-holder, our world's equivalent to the Serpent, which has taken over the position of I think Sagittarius.
Basically, the zodiac uses the positions of stars as they were thousands of years ago, without accounting for the Earth's wobbling on its axis. So, over time, the contellation's positions in the sky in certain times of the year has changed. People born under Ophiucus are born around late November to early December.
For example, under the classical Zodiac, I'm a Taurus (my birthday's the 24th of April), but technically I'm a Leo, if I recall correctly.
Fun stuff.
