What is the origin of the name Albireo?
Albireo’s traditional name appears to be the result of a mistranslation from the ancient Greek word “ornis”, which referred to the entire constellation in which the star appears. It was later translated into Arabic as “urnis”, which was subsequently retranslated in Latin as “Erysimon”, in the mistaken belief that it referred to the Greek name for the plant Sisymbrium officinale. The correct Latin translation, though, should have been “ireo”, but the mistake was nonetheless carried over into the Arabo-Latin Almagest of 1515. In time, the confusion that stemmed from the original mistranslation was compounded when “ab ireo” was thought to be a mistranslation or miscopy of an Arabic term or word by an unknown scribe, and “ab ireo” was subsequently changed into “al-bireo”. However, medieval Arab records list Albireo as “minqar al-dajajah”, which translates into Latin as “Rostrum Gallina” meaning “the hen’s beak”.
