Yes. Though it didn't get that designation until 250 years ago when printmaking made it possible for books to travel outside of the kingdom of Boinu which held the primary legend of the constellation. Though the legend probably goes back further than that since the Boinu Kingdom itself was founded by the second son of Alabastan Royalty.
At any rate, the legend behind the constellation revolves around a young couple, tragically separated by an evil priest, the man in the East Blue, the lady in the west and it details their arduous journey back to the homeland, using the light of the constellation to guide their way to the middle star of the phoenix, also known as the heart star and used by sailors for many centuries to find true north.
Though, of course the true implications of the heart star would be different if you consider that Alabasta is on the Grand Line where such things don't matter, and I believe there it carries the connotation that home is where both parties can meet after a long journey.
