Aquila, the Eagle, is one of the official IAU constellations. Its history goes back to a Sumerian constellation (TI8mušen, The Eagle or The Vulture) in the same area of the sky. In Babylonian uranography, the neighboring constellation is a corpse, and in Ptolemy's Almagest the asterism of Antinous (a recently passed away and deified favourite of the Roman emperor Hadrian) is split off.
Etymology and History

"Aquila" for Eagle is the Latin translation of the Ancient Greek term (Αετός) for Eagle which is the translation of an Akkadian term (erû/ arû) which is the translation of a Sumerian term (mulTE8) for Eagle. It is unknown whether the Sumerians distinguished between eagles and vultures. The Greek term and mythology clearly refer to an eagle as a symbol of divine power. Still, the original Sumerian constellation might have had a different context: as it was placed next to the Sumerian constellation of The Corpse (AD6, pagru), the bird might have been considered a vulture.
The confusion of the Eagle and the Vulture can be traced throughout all epochs. In medieval manuscripts Aquila was also commonly known as "vultur volans", see Saxl-Project while similarly, the (originally Arabian) eagle in Lyra also got the Latin name "vultur cadens". These names are preserved in late-medieval European astrolabes, star catalogues and from the sixteenth-century onwards on celestial globes. See for example the celestial globe (1551) of Gerard Mercator. The term "lucida vulturis" for Altair remained popular until far into the 17th century, and Bode's celestial atlas uses the German rhyme "der Geyer mit der Leyer" (the vulture with the lyre) for Lyra.
[1]However, the arrow is not depicted on the Farnese Globe, as some of the smaller constellations are missing there. There is also no room for it because the eagle is hanging upside down, its head resting on the brightest star and its feet pointing towards the swan: it looks as if the swan is pecking at the eagle's talons. Compared to the image we can draw using the Almagest star catalogue, this Greek eagle is rotated by 180°.
In fact, the constellation of the eagle can also be found in this position in the sky in Mesopotamian astronomy of the 2nd millennium BCE. This suggests that the constellation was adopted into Greek culture from Babylon: although it does not belong to the zodiac, it is close to it and mythologically intertwined with Aquarius in the zodiac.
Interestingly, near the Babylonian eagle is the Babylonian constellation ‘Dead Man’ or ‘Corpse,’ which has no analogue in Greek. It may have been located in the area east of the star Atair in Aquila, but it is impossible to say for sure. It is possible that Babylonian uranography referred to the constellation Delphinus as the corpse. Alternatively, the corpse could also have been located further south, i.e. ‘below’ the eagle. Calculations of Babylonian constellations do not allow for an exact position in declination, but only an estimate of the area in right ascension.
One argument in favour of the southern variant is that Ptolemy simply renamed a group of stars in Aquila in his Almagest, calling them ‘Antinous’. This young man was a favourite of the contemporary Emperor Hadrian and could be stylised in modern terms as the constellation of homosexual love – although pederasty in ancient times had a different, more initiatory and educational character. All that is known about Antinous is that he drowned in the Nile in 130 CE for unknown reasons, whereupon a new cult was established throughout the Roman Empire: festivals were invented, temples built and other things done in his honour, so that his death by the astronomer in Alexandria comes as no surprise. However, he depicts him as a dead man carried by the (established) constellation Aquila. The figure of the double constellation ‘Aquila with Antinous’ in Ptolemy can be reconstructed from the star names and coordinates, and this eagle does not have outstretched wings, but flies from west to east. He is depicted in profile.
Since Ptolemy makes numerous references to direct Babylonian sources, for example by using data on solar and lunar eclipses from there, it cannot be ruled out that his Antinous corresponds to the Babylonian constellation of the corpse.
Incidentally, the interpretation of the bird as an eagle is unclear for the Babylonian constellation: the language does not allow for a distinction between eagles and vultures. A vulture as a scavenger would suggest a very old interpretation of the constellation, which could perhaps even be related to the hygienic and medically advisable burial of the dead. A vulture next to a corpse makes more sense in this respect. However, when it comes to ideas about life after death, the eagle is more appropriate: in Sumerian and Babylonian culture, it is a symbol of life, which is best illustrated in the ancient myth of Etana. The constellation is also located in the Milky Way, which is interpreted in numerous cultures as a road to the afterlife, so that a connection to the cult of the dead is virtually inevitable.
Regardless of whether it was an eagle or a vulture, this constellation of a bird of prey has been found in Mesopotamian culture at that point in the sky since at least MUL.APIN.
Origin of constellation
The constellation of The Eagle mulTE8 is listed in the Mesopotamian creation myth "Enuma Anu Enlil", in Astrolab P and Astrolab B, and in MUL.APIN's first list, all dating to the 2nd millennium BCE.

Aratos
[311] Ahead of the Archer is another Arrow lying all by itself without a bow. The Bird is outstretched beside it, nearer to the north. Close to it another bird is wafted, inferior in size, but stormy when it rises from the sea at the departure of night; and men call it the Eagle. (Kidd 1997)
The popular didactic poem by Aratos describes this bird as ‘dangerous when it emerges from the sea’ and calls it ‘the blown away’. Etymologically, this may be correct, but eagles do not emerge from the sea. The sentence therefore does not refer to the animal, but to the astronomy of the sunrise.[1]
Eratosthenes
Eratosthenes believes that the eagle is the only bird that flies towards the sun without ducking away from its rays. He explicitly mentions that the eagle is depicted with outstretched wings, as if it were swooping down. Its head is therefore facing south towards Aquarius and its tail feathers point north towards Lyra and Cygnus. Germanicus in Roman times supports this idea with his description of the eagle guarding the arrow of Eros, which makes humans and even Zeus fall in love. On the Carolingian Aratea, the eagle is therefore depicted holding the arrow in its talons.[1]
Pamias and Zucker (2013,[2] 91-93)
Var. 1 (Περὶ τοῦ Ἀετοῦ): This is the one who carried Ganymede up to heaven for Zeus, so that he might have a cup-bearer. There was another that belonged to Zeus [?]. For when the gods divided the birds among themselves, this bird fell to Zeus. It is, moreover, the only bird that flies towards the sun; and it has supremacy over all the others. Even amongst the constellations, it is oriented towards the rising sun. It is depicted with outstretched wings as if gliding.
Aglaosthenes says that Zeus, at his birth, was hunted down in Crete and was therefore secretly transported to Naxos; when he had finished growing and reached adulthood, he seized the kingship. When he set out from Naxos to fight the Titans, an eagle appeared.
Var. 2 ( Ἀετοῦ): This is the bird that carried Ganymede up to Zeus in heaven to serve as his cup-bearer. It is counted among the constellations because, prior to this episode, when the gods divided the birds among themselves, this bird fell to Zeus. It is, moreover, the only animal capable of flying towards the sun without its rays diverting its flight towards the earth, and it holds supremacy over all others. It is depicted with its wings spread, as if gliding.
Aglaosthenes says in his *Naxica* that Zeus, upon his birth in Crete, as he was mercilessly hunted down [and secretly abducted on two occasions], was taken from Crete and transported to Naxos; when he had finished growing and reached adulthood, he seized the divine kingship. When he set out from Naxos to fight the Titans, an eagle appeared and flew alongside him; Zeus saw this as an omen and made this bird his sacred bird [once it had been deified], and that is why it was deemed worthy of the honour of appearing in the sky.
The Eagle has four stars, one of which, the middle one, is bright.

Mediaeval, Renaissance and Early Modern SourceAlfonsine Tables (1483)In 1483 the printer Erhard Ratdolt, working in Venice, published Tabulae Alphonsinae or the Alphonsine Tables, a compilation of astronomical data tabulating the positions and movements of the planets. Dürer (1515)The pair of celestial maps created by Albrecht Dürer in 1515, one showing the Northern Hemisphere sky and the other the Southern Hemisphere sky, are generally regarded as the first printed star charts published in Europe. Schickard wrote it ... . Bayer and de Houtman (1603)In his Uranometria, Bayer gives all the name alternatives mentioned above: Rudolphine Tables (1627)The Tabulae Rudolphinae were ordered and dedicated to Emperor Rudolph II of the Holy Roman Empire. The main purpose was to allow the computation of the positions of the five classically known planets, but the tables also consist of a star catalogue. They were published by Johannes Kepler (1627), including earlier work and observational data by Tycho Brahe. The original Latin title is "Tabulæ Rudolphinæ, Quibus Astronomicæ Scientiæ, Temporum longinquitate collapsæ Restauratio continetur". An alternative name for Aquila, the Eagle, is given: The Flying Vulture, Vultur Volans. This bird also carries Antinous. Transfer and Transformation of the constellation
MythologyGreekHyginus, librarian to the Roman emperor Augustus, tells a story of an eagle and a swan: when Zeus fell in love with Nemesis, goddess of righteous wrath, he had to resort to trickery to seduce her. He transformed himself into a swan and had his eagle pursue him. Taking pity on the pursued, Nemesis gave the swan refuge in her lap, and Zeus, satisfied, placed his eagle in the sky. According to another legend, the eagle was Zeus's attribute animal, accompanying him since his campaign against the Titans. Eratosthenes leaves no doubt that it was the eagle who brought Ganymede to Zeus. Referring to the youth of Zeus, who was raised on Naxos and then fought against the Titans, Eratosthenes reports that an eagle joined Zeus and accompanied him. Because he saw this as a good omen, Zeus later declared the animal sacred. When the gods divided the birds among themselves, Zeus received the eagle, as it ruled over all birds. BabylonianThe eagle probably originates from the Sumerian myth of Etana. According to the royal lists, Etana is said to have been the first Sumerian king after the Flood. Since the neighbouring constellation of Aquarius is associated with this flood, the placement of the eagle in its immediate vicinity makes perfect sense in Mesopotamian thinking. Since the Etana myth dates back to at least the 24th century BC and may even be older, this connection could also suggest that the constellation Aquila is much older than the invention of writing. The myth already attests to the eagle's symbolism of life. According to legend, Etana was childless, which saddened him greatly. A helpful eagle carried him on its back to the sky, where he wanted to fetch the life-giving ‘herb of childbirth’. The myth tells how Etana climbs higher and higher on the eagle's back, sees the earth from above and describes what he sees. Shortly before reaching the herb, the eagle and its rider fall. The story provides interesting insights into the imagination of people who were already able to picture what the earth might look like from above. Weblinks
