This name derives from the Latin “lunae > lūna”. In ancient Roman religion and myth, Luna is the divine embodiment of the moon. She is often presented as the female complement of the sun (sol) conceived of as a god. Luna is also sometimes represented as an aspect of the Roman triple goddess (diva triformis), along with Proserpina and Hecate. Luna is not always a distinct goddess, but sometimes rather an epithet that specializes a goddess, since both Diana and Juno are identified as moon goddesses. The equivalent in Greek mythology is Selene, sister of Aurora and Sol. The day "Monday" in is an interpretation of the Latin “lunae dies (day of the moon)”.
