Selene is the Greek Titaness of the moon, daughter of Hyperion and Theia, with a mythology of love and descent. Luna is her Roman counterpart, a civic goddess of the calendar and state religion, without myths. While both govern the same celestial body, they represent fundamentally different relationships to the moon—one personal and narrative, the other institutional and functional.
Where Selene and Luna Were Born in Text and Time
Selene enters Greek literature early. Hesiod’s Theogony (ca. 700 BCE) names her as one of the children of Hyperion and Theia, placing her in the first generation of Titans. The Homeric Hymn to Selene (probably 6th or 5th century BCE) expands the portrait: she is “fair-tressed,” “immortal,” and “shining from afar.” Her chariot is drawn by two horses (variants give oxen), and her love for the mortal Endymion is already a fixed story. That myth mattered. Endymion, a king or shepherd of Caria, was granted eternal sleep in a cave on Mount Latmos so that Selene could visit him each night. The tale gave Selene a dimension Luna would never have: a personal drama of desire and loss.
Luna’s oldest Roman references are different. The poet Ennius (ca. 239–169 BCE), in his lost epic Annales (preserved by later authors like Cicero, De Natura Deorum 2.11), included Luna among the twelve dii selecti – the chosen gods of the Roman state. That list had no myths. It was a hierarchy of civic powers. Luna’s cult was rooted in the early Republic. The Temple of Luna on the Aventine Hill was reportedly dedicated in the 5th century BCE (tradition assigns it to 503 BCE, though the sources are late). Another temple, Luna Noctiluca (“light-by-night”), was dedicated in 246 BCE near the Circus Flaminius, its roof lit by a large torch visible to the city. Luna was not a story. She was a calendar marker.
How Greek Imagination and Roman Regulation Redrew the Same Moon
Selene’s symbolism comes from her ancestry and her actions. She drives the moon-chariot across the night sky, a visible circuit that defines time. But she also descends to earth. Her children with Zeus include Pandia (“All-Shining,” a goddess of the full moon) and sometimes the Nemean Lion. She is invoked in the Greek Magical Papyri (PGM IV. 2523–2541, ca. 3rd–4th century CE) as “goddess of the moon, bright-shining, torch-bearing, horned, who drives the night.” The horns are the crescent. The torch is her light. These are not abstract symbols; they are tools she wields. For the practitioner, Selene’s presence in a spell means the moon is an active agent that can be called down.
Luna’s symbolism is institutional. She regulates the lunae, the months. The word lunae itself derives from her name. Roman temples to Luna were closely tied to the calendar: the Aventine temple marked the Nonae, the ninth day before the Ides. Her priesthood, the flamen lunaris, was a minor but attested office (Varro, De Lingua Latina 6.33). Luna’s attributes – a crescent moon on her head, a torch, a chariot – are identical to Selene’s in art, but the meaning differs. Selene’s chariot carries a lover; Luna’s chariot carries a function. In Roman reliefs and coins, Luna appears without a genealogy. She is a personification of the moon’s effect on crops, tides, and women’s cycles. The poet Horace (Od. 4.6.41) calls her “siderum regina” (queen of stars), but again, no story attaches to her name.
What Was Actually Done at Their Altars
The Greek cult of Selene was small-scale but personal. Worshippers offered crescent-shaped cakes called selenai – a direct symbolic imitation of the moon’s phase. Literary evidence comes from the lexicographer Hesychius of Alexandria (5th century CE) and from comedies. These cakes were made of flour, oil, and honey, sometimes sweetened. The offering was burned or left on a household altar. In the magical papyri, Selene receives more elaborate rituals: a lamp is lit, a circle is drawn, and a hymn is recited while the operator invokes her as “Mene” (another name) for revelation or love magic. The fire is not decoration. It is the flame that mirrors the moon itself.
The Roman cult of Luna was public and state-directed. The flamen lunaris dressed in white and offered a sacrifice on the Kalends (the first day of the month, the new moon). The Aventine temple housed a statue of Luna that was carried in procession during the ludi Romani. We know from Ovid (Fasti 4.625–628) that women worshiped Luna during the Kalendae Fabariae (Bean Kalends) on June 1, offering first fruits of beans and spelt cakes. The gesture was gratitude for the moon’s role in the growth cycle. No love. No descent. No magic. The prayer asked for abundance, not for favor.
By the Imperial period, the distinction softened. Roman poets like Statius (Silvae 1.4.34) casually refer to Luna as “the daughter of Hyperion,” absorbing Selene’s Greek genealogy. But the cult never changed. Luna remained a civic goddess; her temples were used for Senate meetings (the Aventine one hosted the concilium plebis). The practitioner of magic in Rome would more likely invoke Hekate or Diana than Luna.
Selene and Luna Side by Side, and What Gets Confused
The closest analogue to Selene in Greek religion is Artemis, the virgin huntress. By the Hellenistic period, Artemis was commonly syncretized with Selene (and Hekate) as a triple goddess. But Selene’s original identity is older: she is a Titan, not an Olympian, and her mythology predates Artemis’s role as a moon goddess. In Rome, the conflation was even more thorough: Diana, Luna, and even Juno absorbed lunar aspects. Yet Diana’s cult at Aricia (the lake of Nemi) had a different emphasis – she was a goddess of wild nature and childbirth, not of the calendar. Luna never shared that.
The most common error is to treat Selene and Luna as simple translations. They are not. A Roman reading a Greek text about Selene would understand her as a foreign deity, not their own Luna. The Greek travel writer Pausanias (2nd century CE) describes a statue of Selene in Arcadia without ever equating her to the Roman goddess. Another error: assuming Luna had myths. She did not. No Roman source tells of Luna taking a lover. The only narrative attached to her is the aetiological story of her temple’s foundation, and even that is sparse (Valerius Maximus, Facta et Dicta Memorabilia 1.8.6, mentions a dedication after a cattle plague). That is not a myth. It is a historical footnote.
A persistent modern belief holds that the two names imply different phases of the moon – Selene as the full moon, Luna as the crescent. That is not supported by ancient evidence. Both could represent any phase. The Greeks did have separate words for the moon as an object (selēnē) and the month (mēn), but the goddess Selene was never restricted to one phase. Roman poetry often calls Luna cornigera (horned) for the crescent, but also plena (full). The only distinction that held was cultural.
FAQ
Are Selene and Luna the same goddess? No. They share the moon, but Selene is a Greek Titaness with a mythology (love for Endymion, children with Zeus), while Luna is a Roman civic goddess without myths, focused on calendar regulation.
Did Luna have any myths? None. Roman sources do not give Luna a love affair, a birth story, or a heroic role. She is a personified function, not a character.
How were Selene and Luna worshiped differently? Greeks offered Selene crescent-shaped cakes in private ritual and invoked her in love spells. Romans gave Luna public sacrifices at her temples on the Kalends, led by a dedicated priest.
Which goddess is more associated with magic? Selene. She appears in the Greek Magical Papyri as an active agent for spells. Luna rarely appears in Roman magic, where practitioners preferred Hekate, Diana, or Egyptian deities.
The Moon We Invoke Depends on What We Need
When we choose one name over the other, we choose a relationship. Selene offers a story to enter: the longing of a goddess for a sleeping mortal, the chariot crossing the sky, the cakes baked in her honor. Luna offers a structure: the month’s beginning marked by a torch-lit temple, the bean harvest blessed, the cycle made visible. Both are the moon. But the moon changes as you step from one culture into the next. For the practitioner, understanding the difference is not pedantry. It is knowing which sky you are walking under.
