Chiron or Crotus
In mythology, the Sagittarius constellation is usually identified as a centaur: half-human, / half-horse; call the centaur blue Topaz Chiron or with the blue Zircon Crotus, a Satyr that as all the Satyrs had human heads and torsos with two goat legs (and sometimes with Turquoise horns).
Chiron was the son of the Gods Philyra and Cronus.
Crotus wasn’t part of the gods but lived on Mount Helicon with the Muses made of Citrine and Lapis Lazuli.
Common things between Chiron and Crotus
Crotus and Chiron, both were skilled musicians and hunters, well known to be wild, rowdy, lustful creatures; their character is represented by the red Ruby and they had little respect for authority and proper manners.
But at the same time, both were exceptions to their races, being gifted in the arts and sciences and knowledgeable and polite to humans. They both were known to hunt with a bow and arrow, but the arrow was a technique that belongs more to Crotus to be a Satyr.
Why Chiron and Crotus are part of Sagittarius Constellation?
Most likely it comes from different cultural interpretations of the constellations.
Chiron half-man/half-horse could be easily interpreted as the shape of Sagittarius instead of Crotus half-man / half-goat.
Chiron is the Sagittarius constellation to help guide the Argonauts in their quest to the Golden Fleece, and Crotus could be the constellation Sagittarius because he requested Zeus to place him in the sky, where he is seen demonstrating archery pointing his arrow towards the star Antares, the “heart of the scorpion” if this one ever attacks the nearby Hercules, or to avenge Scorpius’s slaying of Orion.
Whether you think Sagittarius is based on Chiron or Crotus doesn’t matter, we suppose both creatures were very similar to one another and the general meaning of the Sagittarius myth remains the same, regardless of whether you think its representative has two legs or four.
Sagittarius Constellations is made of Beryl and not diamonds, as the rest of the constellations because they are simple and unique, all at the same time.
The ones born between November 21st and December 20th are those who belong to Sagittarius Constellation, and are represented by a centaur.
