In the Night Sky, the River Eridanus starts at the left foot of Orion and continues until Auriga or the star Achernar (which literally means the end in Arabic). Great Rivers such as the Ganges, the Tigris and the Nile were sometimes seen as mirrors of the Eridanus in the heavens. The Euphrates was also associated with the Eridanus. cf. http://www.nrm.se/theswedishmuseumofnaturalhistory/exhibitionsandcosmonova/cosmonova/whatsupthismonth/engwujanuary2006.4.5fdc727f10d795b1c6e800022064.html
To the ancient Egyptians it was the Nile, to the Romans the Po, while the Chinese thought of it as theirYellow River . Some have even claimed it to be either the Tigris, or theEuphrates . Interestingly enough, Eridanus is thought to flow northward in the heavens just as theNiledoes on Earth http://www.nrm.se/theswedishmuseumofnaturalhistory/exhibitionsandcosmonova/cosmonova/whatsupthismonth/engwujanuary2006.4.5fdc727f10d795b1c6e800022064.html
Akkadian Aria-Dan, the Strong River. George Smith thinks that the heavenly Eridanus may have been the Euphratean, Erib-me-gali River of Orion ... the stars now known as Arydanus were originally known in various countries by the names of Nile, Nereus, and Ocean or Neptune..... Caesius thought our Eridanus the sky representative of the Jordan or the Red sea which the Israelites passed over as on dry land. http://books.google.com/books?id=x4qVPl-qpNQC&pg=PA217&lpg=PA217&dq=Eridanus+heavenly+jordan&source=web&ots=XokmycnORu&sig=PN2Rfp-IDt1PxjanktYqMX9FDGo&hl=en&sa=X&oi=book_result&resnum=2&ct=result#PPA217,M1
