			'''Eratosthenes's star catalogue''' can be reconstructed from the list of stars he mentions in the last section of each of the constelllation descriptions. Hoffmann (2017)<ref name=":02">Hoffmann, S. M., <nowiki><i>Hipparchs Himmelsglobus</i></nowiki>. Springer Wiesbaden/ New York, 2017. doi:10.1007/978-3-658-18683-8.</ref> made such a catalogue and used it for computational comparison with Hipparchus's, Ptolemy's and Babylonian data; it is based on the edition and translation by Pamias and Geus (2007)<ref>Eratosthenes: Sternsagen, übersetzt von Pamìas, Jordi und Geus, Klaus, Verlag Utopica, Oberhaid 2007</ref> and presented here in English translation.

 One of the [[:Category:88_IAU-Constellations|88 IAU constellations]]. In ancient Greece, the constellation simply had been named ‘The River’ with various interpretations. In Mediaeval times, e.g. in the Leiden Aratea, it is even depicted as a river god instead of a stream of water. The modern IAU-adoption renders the term as "Eridanus".
