With its roots in oral and literary traditions, Greek mythology predates the Roman version by more than a millennium. For the most part, the Greeks envisioned their gods in a familiar human likeness portraying them with, often exaggerated, human traits, emotions, and physical forms. In this way the Greek gods and goddesses espoused both the beauty and flaws of mortal beings. From the thunderous Zeus to the wise Athena, the gods were at the very core of Greek culture influencing everything from art to politics.
Assimilation
While profoundly influenced by the Greeks, Roman mythology emerged in a society with a distinct worldview. The Romans, pragmatic and disciplined, adopted most of the Greek gods and goddesses into their own pantheon, but often changed their names and attributes to better align with Roman values and societal norms. For instance, the Greek god of war, Ares, known for his fierce and tumultuous nature, was transformed into Mars, a more disciplined and virtuous figure in Roman culture.
In the table below is an alphabetical list of the Greek gods and goddesses and their Roman equivalents. The list is by no means exhaustive as there are many more minor deities and other personifications of the natural world within which the superstitious Romans inhabited.
Of those listed above, the principal deities of ancient Greek mythology lived atop Mount Olympus and were thus known as the Olympian gods. They governed all aspects of life, from love and war to wisdom and the natural world. Adopted by the Romans, it is generally accepted that there were twelve Olympians as follows:
Jupiter (Zeus) For both the Greeks and Romans, Jupiter/Zeus is often referred to as the King of the Gods. He was not the original creator of the mythological creatures that dominated tales and lore as that distinction belongs to his father, Saturnus (Greek: Kronos). Also known as Jove in Roman mythology, Jupiter was the chief deity of Roman religion, presiding over the sky and thunder, and acting as the guardian of justice, oaths, and treaties in the Roman state. He was considered central to the Capitoline Triad alongside Juno, his consort, and Minerva, his daughter. His sacred tree was the oak, and his primary symbol was the thunderbolt, often depicted in the claws of an eagle, which was also his sacred animal.
Juno (Hera) The Queen of the Gods was the second central deity in ancient Roman religion. She served as the wife and sister of Jupiter, the King of the Gods, and was mother to deities such as Mars, Vulcan, Bellona, Lucina, and Juventas. She was revered as the protector of women, particularly in marriage and childbirth, and held significant civic roles as a guardian of the Roman state. Her sacred animal was the peacock, symbolising her regal status.
Minerva (Athena) Goddess of wisdom, strategy, and warfare, but also of crafts, medicine, and the arts. Minerva originated as an Italic and Etruscan deity, known as Menrva, before being fully integrated into Roman religion as the third of Capitoline Triad. Her name is linked to the Latin root mens (“mind”) and the Proto-Italic meneswo (“understanding” or “intelligence”), reflecting her association with wisdom and intellect. Over time, she was equated with the Greek goddess Athena, adopting many of Athena’s martial and strategic attributes while retaining her original Italic identity as a goddess of crafts and professional skill.
Neptune (Poseidon) God of the sea, earthquakes, and of horses. Known in Latin as Neptūnus, he was initially a god of freshwater sources such as springs, rivers, and wells, reflecting the practical concerns of early Roman agricultural society. Later he became identified with the Greek god Poseidon. Neptune is the brother of Jupiter (sky) and Pluto (underworld), forming part of the ruling generation of Roman gods who divided the cosmos after overthrowing their father Saturnus. Neptune’s wife was Salacia, a goddess associated with saltwater and possibly originally with natural groundwater springs, paralleling the Greek Amphitrite.
Ceres (Demeter) Goddess of agriculture, grain, fertility, the harvest, and motherly relationships. She was a central deity in Roman religion being particularly associated with the growth of wheat and spelt, reflecting the vital importance of grain to Roman survival and society. Her symbols include the sickle, shafts of grain, and the cornucopia, and she is typically depicted as a matronly woman wearing flowing draperies, crowned with wheat ears. Ceres could bring plentiful harvests or, if angered, blight, drought, and famine.
Apollo (Apollo) The son of Leto and Jupiter (Zeus), Apollo was born on the island of Delos together with his twin sister Diana (Artemis), Goddess of the hunt. Both he and Diana shared an aptitude for archery. The nine Muses were companions of his, they being the goddesses known for inspiring art and music. Apollo was a significant deity in ancient Greek and Roman mythology, known for his numerous functions, including healing, prophecy and oracles. He was widely revered with temples dedicated to him across the ancient world, particularly in cities like Athens and Sparta. Apollo is often depicted as a handsome youth associated with the sun, light, music, poetry, and archery.
Diana (Artemis) Goddess of the hunt, the moon, wild animals, childbirth, and virginity. Diana was originally an Italian deity worshipped in the forests and countryside. Over time, she absorbed aspects of the Greek goddess, Artemis, including associations with the moon (Luna/Selene) and the underworld (Hecate), forming a triformis or triple goddess concept. She was the daughter of Jupiter and Latona, born on the island of Delos alongside her twin brother, Apollo. Diana was revered as a protector of the wilderness, a skilled huntress, and a guardian of animals, often believed to communicate with and control woodland creatures. Her name likely derives from the Latin dius (“godly” or “divine”), connecting her to the sky and daylight, and she was sometimes called Diana Lucifera, meaning “light-bearer”.
Mars (Ares) The God of War who represented its violent and chaotic aspects in contrast to Minerva (Athena). Often depicted in bronze armour, emphasizing his martial character, he was the protector of Rome, and originally a guardian of agriculture, second in importance only to his father Jupiter. Being also the son of Juno, the goddess of women and marriage, made Mars a central figure in the Roman pantheon. He fathered Romulus and Remus, the legendary founders of Rome, through Rhea Silvia, a Vestal Virgin, establishing his role as a divine progenitor of the Roman people. As Rome expanded, his warrior aspect became dominant, symbolising military power to secure peace rather than mere destruction in contrast to the Greek god Ares, who was often seen as impulsive and violent. Mars’ worship was closely tied to the Roman calendar. The month of Martius (March), named after him, marked the start of both the agricultural and military seasons, while October marked their conclusion. Mars was associated with the wolf, reflecting his connection to Romulus and Remus, and the woodpecker, a symbol of vigilance and war. His sacred shield, the Ancile, was believed to protect Rome, and priests maintained multiple copies to safeguard the city.
Venus (Aphrodite) The Roman goddess of love, beauty, desire, fertility, prosperity, and victory, and the divine ancestress of the Roman people (Gaius Julius Caesar for example claimed descent from her). She was originally a native Italian deity associated with gardens, cultivated fields, and the beauty of growing things, symbolising charm, grace, and productive abundance in nature. Venus was later identified with the Greek goddess Aphrodite. In Greek myth, Aphrodite was born from sea foam after Uranus (Ouranos), one of the primordial deities representing the sky itself, was castrated by Kronus. Despite Greek influences, Venus retained her earlier Italian character, emphasizing fertility, natural beauty, and the flourishing of life. According to mythology, her son Aeneas fled from Troy to Italy. He became the ancestor of Romulus and Remus, co-founders of Rome.
Vulcan (Hephaestus) A son of Jupiter, king of the Gods, and Juno, queen of the Gods. It was believed that with such parents he would be quite handsome. As a baby, however, Vulcan (or Vulcanus in Latin) was very small and ugly, his face red and distorted. Notwithstanding his looks, Vulcan was married to Venus (Aphrodite). He was revered as the God of fire, volcanoes, metalworking, and craftsmanship. He was known as the master of the forge and patron of artisans, associated with both the creative and destructive aspects of fire. He is often depicted with a blacksmith’s hammer, working at a forge surrounded by flames and tools, symbolising his mastery over metallurgy and craftsmanship. Vulcan is credited with forging powerful artifacts, such as Jupiter’s lightning bolts and Mercury’s winged helm.
Mercury (Hermes) Known in Latin as Mercurius, was the son of Jupiter, king of the gods, and Maia, one of the Pleiades and daughter of the Titan Atlas. His cult was influenced by the Greek god Hermes and the Etruscan deity Turms, blending traits of speed, cunning, and mediation between gods and mortals. Mercury’s name likely derives from the Latin merx (“merchandise”) or mercari (“to trade”), reflecting his association with commerce and boundaries. He was a versatile deity with multiple responsibilities including protector of merchants, shopkeepers, and of financial gain; God of messages, languages, and divination; patron of travellers, transporters of goods, and the keeper of borders. Known for cunning, wit, and cleverness, often using his intelligence to outsmart others, Mercury was also the God of tricksters and thieves. He also guided the souls of the dead to the underworld, uniquely able to cross freely between realms of the living and the dead.
Vesta (Hestia) One of the original twelve Olympians as the firstborn child of the Titans Kronus and Rhea. She chose to remain a perpetual virgin, rejecting marriage proposals from gods such as Neptune (Poseidon) and Apollo. Instead, she dedicated herself entirely to being the Goddess of the hearth and domestic harmony, being revered as the guardian of family. Vesta ensured the hearth fire in every household remained burning thereby symbolising stability, warmth, and continuity of family life. Her symbols include the aforementioned hearth, fire, and kettle, while her sacred plant is the chaste-tree and her sacred animal is the pig. She is often depicted as a modest, middle-aged woman, sometimes standing by a fire or holding flowers. In some lists of the twelve Olympians, Vesta is omitted in favour of Bacchus (Dionysus), so some cany readers will note that the twelve have a thirteenth member.
Bacchus (Dionysus) Bacchus is the Roman counterpart of the Greek god Dionysus, who is associated with wine, fertility, and ecstatic celebrations. He is often depicted as a youthful figure, crowned with ivy and holding a thyrsus (a staff entwined with vines). Bacchus was born to Jupiter (Zeus) and the mortal Semele. His birth is unique as he is considered “twice-born” first from Semele and then from Jupiter’s thigh after Semele perished upon seeing Jupiter in his divine form. Bacchus represents not only wine and festivity but also the liberation of the human spirit from societal constraints. He is often associated with the concept of bacchanalia, wild festivals that celebrate his influence, where participants engage in music, dance, and revelry.
One notable exception to this list is Pluto (Hades), one of three brothers and two sisters born to the Roman god, Saturnus, and his goddess wife, Ops. Upon the death of Saturnus and after the defeat of the Titans, the three brothers divided the realm of their father. Jupiter received the sky as his dominion, Neptune the sea, and Pluto the underworld. So, while Pluto was a major deity in first the Greek pantheon, being a brother of Zeus and related to the other Olympians, his realm of the underworld was far away from Mount Olympus. Pluto therefore was not usually considered to be one of the twelve. Bon appétit!
