Name origin

traditional Chinese single star asterism: an auxiliary road to Gedao; also represents the chief assistant to maintain roads. Gedao (the flying corridor) is a long chain of stars next to the Purple Palace enclosure constellation. Paradoxically, the auxiliary road is considered a single star asterism as attested in several historical star charts (e.g. the famous Suzhou map). Sun and Kistemaker (1997) who studied sources from the Han dynasty (around the year "0" plusminus 200 years) identify ζ Cas with this single star. Another researcher, Sun Shuwei, who dealt with the Xinyixiangfayao Star Map from Su Song (苏颂, 1020-1101 CE) identifies δ Cas. Both is plausible.
