Aquarius and "surrounding"
Aquarius-constellation's alpha star is the star Sadalmelik - not very bright and not very known. Known is Formalhaut of Pisces Austrinus as he's the 4th watcher and is assigned to Archangel Gabriel. Pisces Austrinus lays south of the ecliptic a bit above Sculptor, south of which we see the Phoenix rising but just below that the Star Achernar marking the end/delta of Eridanus, the river of life.
Quite north of the ecliptic we see Cygnus, the beautiful Swan, with it's alpha star Deneb. Between Aquarius and Cygnus in latitude we see the hint legs of Pegasus.
Aquarius is of fixed air "ruled" by modern Uranus.
Traditionally Aquarius is future orientated. A humanitarian and Scientist. Technology does play a role here. Also Aquarius is about groups, corporations and all kinds of clubs - anything in this meaning.

Cygnus "the Swan" and it's alpha star Deneb:
As with all constellations, there are many different myth and tales told in the various ages/epochs and parts of the world. Some of the myth are talking about sacrifice and others about bridging - I think both should be taken into consideration when talking about Cygnus. Interesting is also that Deneb (the swan's tail) is the same time part of the so called "summer triangle", formed by first Deneb, Vega (Lyra) and Altair (Aquila).
Deneb is also a star, that has been mentioned in very ancient Egyptian Astronomy and Astrology. It has been ages ago, the Polestar and is therefore linked to the bigger evolutionary cycles our Earth is part of.
Aquarius constellation and Myth:
In most of the stories, Aquarius is a water-bearer. In Greek mythology, the most famous story is the one, of
Ganymede a young Trojan man, who was "abducted" by Zeus to stay on Mount Olympus to become a servant there (in different ways though). In newer Egyptian myth, it's the god that controls the river Nil.
So in either myth, it's about the water, that brings nourishment to the Earth and therefore flourishing agriculture for the people. Truly a Humanitarian picture drawn here..... Interesting is, that the water flows into the mouth of Formalhaut and it's constellation Pisces Austrinus, which connects the "structures" of Capricorn, as does further up, Cygnus in the more airy realms.
Eridanus - the river of life - the "delta" of Achernar:
In Greek myth the story of the river is pretty sad - Helios's Son did ask to steer the chariot along the ecliptic for a day. He wasn't able to control the horses and went north and south, that it had extreme happenings on Earth as a consequence. Zeus did burn the chariot down and Phaeton did fall into Eridanus dead and his close Friend Cycnus (one of the many tales about the Cygnus-Swan constellation) dove into the river in form of a swan to rescue his Friend....
Achernar was of so much sothern declination, that for a long time it wasn't seen anymore from the northern hemisphere. It was listed in more ancient asterism but not in the famous one of Ptolemy. So, when it was re- discovered in the ca 17th century, it became an "extension" of the river Eridanus.
