Hyginus edition 1535, but the 1482 edition from Ratdolt should have been rather similar.

"II.29 AQUARIUS OR WATER BEARER
Aquarius or Water Bearer. Many have said he is Ganymede, whom Jupiter is said to have made cupbearer of the gods, snatching him up from his parents because of his beauty. So he is shown as if pouring water from an urn.
Hegesianax, however, says he is Deucalion, because during his reign such quantities of water poured from the sky that the great Flood resulted.
Eubulus, again, points out that he is Cecrops, commemorating the antiquity of the race, and showing that men used water in the sacrificed of the gods before wine was given to them, and that Cecrops ruled before wine was discovered.
II.43 MILKY WAY
There is a certain circular figure among the constellations, white in color, which some have called the Milky Way. Eratosthenes says that Juno, without realizing it, gave milk to the infant Mercury, but when she learned that he was the son of Maia, she thrust him away, and the whiteness of the flowing milk appears among the constellations.
Others have said that Hercules was given to Juno to nurse when she slept. When she awoke, it happened as described above. Others, again, say that Hercules was so greedy that he couldn’t hold in his mouth all the milk he had sucked, and the Milky Way spilled over from his mouth.
Still others say that at the time Ops brought to Saturn the stone, pretending it was a child, he bade her offer milk to it; when she pressed her breast, the milk that was caused to flow formed the circle which we mentioned above."
The topic star catalog developed necessarily in its icongraphy: as the nicest representation is taken the ceiling of the Sala da Mappamondo (ca. 1575) in the Palazzo Farnese.
Here they found to this representation (detail with Aquarius and Eridanus, which are near to each other):
... and itself the Sala looks like this (just to give an impression)
