tau02 Eri (HR 850) is known by the proper name "Angetenar" in the Bright Star Catalog and various astronomical references going back at least 8 centuries:
(1) Tabule Astronomice Alfonsi Regis (1492), print of "Alfonsine Tables" (1252) ["Angetenar" for 19th star in Eridanus, 4th magnitude].
(2) Petrus Apianus (1540) "Astronomicum Caesareum" (Ingolstadt; http://www.atlascoelestis.com/apianus%20013.htm).
(3) Ioannis Bayeri Rhainani I.C. (1603), Uranometria ["Angetenar" or "Anchenetenar"].
(4) Ephraim Chambers (1728) "Cyclopaedia" https://artfl-project.uchicago.edu/node/88 ["Argetenar" or "Argeteyiar"].
(5) Richard Hinckley Allen (1899) "Star-names and their meanings" (G.E. Stechert, New York) ["Angetenar", from Alfonsine Tables].
(6) Paul Kunitzsch (1959) "Arabische Sternnamen in Europa".
(7) Jack W. Rhoads (1971) "Technical Memorandum 33-507: A Reduced Star Catalog Containing 537 Named Stars", Jet Propulsion Laboratory California Institute of Technology, Pasadena, CA, USA ["Angetenar"].
(8) Paul Kunitzsch (1989) "The Arabs and the Stars" (Otto Harrassowitz, Wiesbaden).
(9) Dorris Hoffleit & Carlos Jaschek (1991) "The Bright Star Catalogue" (5th edition; Yale University Observatory, New Haven, CT, USA) ["Angetenar", "Al Anchat al Nahr", "Anchat"].
(10) P. Moore (2006) "The Amateur Astronomer" (12th edition, Springer) ["Angetenar"].
(11) E. Anderson E. & C. Francis (2012, Astron. Letters, 38, 331) "XHIP: An Extended Hipparcos Compilation" (2012AstL...38..331A) ["Angetenar"].
While Bayer (1603) assigned "Angetenar" to "tau" (there are now two stars tau01 Eri and tau02 Eri), the ID of the name to tau02 Eri in the Alfonsine Tables is unambiguous. tau02 Eri is the 19th star in Eridanus in the Alfonsine list, and tau01 Eri (two degrees north) is the 18th. Toomre (1998; "Ptolemy's Almagest"), Manitius (ed. B.G. Teubner, 1913; via C. Jaschek; http://cdsarc.u-strasbg.fr/viz-bin/Cat?V/61), and Kunitzsch (1989) independently agree that the 19th star in Eridanus in the Almagest is tau02 Eri (HR 850). The name comes from the Arabic phrase for "bend of the river", so it appears to be a Latinized Arabic name (alluding to a feature in a Greek constellation) that appeared on medieval astrolabes and included in medieval star catalogs.
