Eridanus is the constellation of the River, and probably represents a generic river. "Etymologically, the term river denotes the 'banks' of a river, rather than the water that flows between them. Its distant ancestor is Latin ripa 'bank'" [Ayto], 'that which is cut out by the river'. The word river comes from the Indo-European root *rei-1'To scratch, tear, cut', from the extended form *reip-. Derivatives: rive (from Old Norse rifa, to tear), riven (torn apart), rift (from Middle English rift, rift, from a Scandinavian akin to Danish rift, breach, from Germanic *rifti), rife, (from Old English ryfe abundant), riparian ('of a river bank'), rivage (shore),river (French riviere, 'river', 'land lying along a river; river', from Late Latin riparia, 'land lying along a riverbank', feminine of riparius, 'of a riverbank', from ripa, 'riverbank'), arrive ('to reach the shore'), rivet(from Latin ripa, bank < 'that which is cut out by a river'). [Pokorny 1 rei- 857. Watkins]
Eridanus/ɨˈrɪdənəs/ is a constellation in the southern hemisphere. It is represented as a river; its name is the Latin name for the Po River. It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations. It is the sixth largest of the modern constellations.

The name Eridanos, derived from the ancient Greek Eridanos, was given by geologists to a river which flowed where the Baltic Sea is now (Overeem, et al., 2002). Its river system was better known as the 'Baltic River System' (Bijlsma, 1981; Gibbard, 1988).
The Eridanos began about 40 million years ago in the Eocene. By about 12 million years ago in the Miocene, the Eridanos had reached the North Sea area where sediments carried by the river built an immense delta. The Eridanos disappeared in the early Middle Pleistocene when the Ice Age glaciers excavated the Baltic Sea bed.

THE GREAT STAR, !GAUNU, WHICH, SINGING, NAMED THE STARS.
!gaunu, he was formerly a great Star; therefore, his name is !gaunu; while he feels that he was the one who formerly spoke (lit. "called") the Stars' names; while he feels that he is a great one. Therefore, he called the Stars' names. Therefore, the Stars possess their names; while they feel that !gaunuwas the one who called their names. He formerly sang, while he uttered the Stars' names. He said "||Xwahai" to (some) Stars which are very small; they are those of which he made ||Xwhai; their small, fine ones are those which are ||Xwhai. Therefore, the porcupine, when these Stars have, sitting, turned back, he will not remain on the hunting ground; for, he knows that it is dawn, when||Xwhai has, lying, turned back. He returns home; for, he is used to look at these Stars; they are those which he watches; while he feels that he knows that the dawn's Stars they are. [1. My (paternal) grandfather, |Xugen-ddi, was the one who told me star's stories." 2. The stars ||Xwahai |aiti and ||Xwhai-@pua were identified as "Altair" or "Alpha Aquilae", and "Gamma Aquilae", respectively, by the late Mr. George Maclear and Mr. Finlay of the Royal Observatory, on October 10, 1873, at Mowbray. ||Xwhai gwai was behind a tree and too low to be distinguished.]
