Azelfafage is a modern star name adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is Arabic. It is the name of HIP 107136 (π¹ Cyg, HR 8301) in constellation Cyg.

Etymology and History

From the sci-A constellation name al-sulahfat, "the Tortoise", for Lyra ( corresponding to the Greek image of a tortoise shell for the Lyre's soundboard). Transliterated as Azelfage, a Medieval Latin translator erroneously attributed this constellation name to Cygnus. Then in Renaissance times, the corruption "Azelfafage" was applied as a star name to π¹ Cyg.
