Which Roman goddess was the personification of the moon? The answer is Luna.
Luna was the Roman divine embodiment of the Moon and was often imagined as the female counterpart of Sol, the Roman sun god. Her name is simply the Latin word for “moon,” and it survives in modern terms such as lunar. In Roman religion, she represented the visible celestial body and its regular movement across the night sky.
Roman artists commonly depicted Luna with a crescent moon and a two-horse chariot called a biga. She was often paired with Sol, who drove a four-horse quadriga. This visual pairing expressed the complementary cycles of night and day. Monday’s Latin name, dies Lunae, literally means “day of the Moon,” a pattern preserved in several modern languages.
Luna’s Greek counterpart was Selene, and Roman artists and writers adapted Selene’s myths—including the story of her love for the sleeping Endymion. Luna was also sometimes treated as an aspect of a triple goddess alongside Diana and Proserpina or Hecate. That overlap explains why Diana can also be described as a moon goddess, but Luna is the most direct answer when the question asks for the Moon’s personification.
