Piautos

The IAU catalogue's account

piautos (πιαυτος) is a composition from Greek autos ("self") and Coptic pi- ("that") meaning "the same one". It occurred in a Coptic manuscript on lunar stations. Coptic is the ancient Egyptian language written in Greek letters, but lunar stations were uncommon for both the Greek and Egyptian culture. Hence, the origin of this term remains unknown.
