Name origin

The formation of this name begins with one of the words used by Ptolemy to describe this star in the Almagest: καμπή, "the bend [of the river]". This was misread by the sci-Arabs, who transliterated the word as bhmn. This, in turn, was transliterated as beemun in the Medieval Latin Almagest, which was corrupted to beemin, beemim, etc. Then in Renaissance times, the derivation of the form beemim was erroneously attributed to the Hebrew word te'omim, "twins." Subsequently this erroneous word, written as Theemim, then "Theemin," was applied as a star name to any of the various dim stars running from u1 to h Eri.
