Janus, the two-faced Roman god of beginnings, endings, doorways, and transitions, does not have a single, universally agreed-upon family tree. In the earliest Roman sources, he is presented as a primordial deity with no parents, while later Greek-influenced writers gave him various genealogies. The most consistent and widely attested tradition, however, names his father as Caelus (the sky, equivalent to the Greek Uranus) and his mother as Tellus or Terra (the earth, equivalent to Gaia). This article explores the different versions of Janus’s lineage, his consorts, his children, and his place in Roman mythology.
Janus in Roman Religion: A Primer
Before diving into his family, it is essential to understand who Janus was. He was one of the most ancient and distinctly Roman gods, with no clear Greek counterpart. His name is linked to the Latin word ianua (door) and ianus (archway). He presided over all beginnings, including the first hour of the day, the first month of the year (January, Ianuarius), and the start of all human enterprises. He was also the god of transitions, gates, and passages, both physical and metaphorical. His most famous depiction shows him with two faces, one looking forward and one backward, symbolizing his ability to see the past and the future. The most important temple dedicated to him was the Ianus Geminus in the Roman Forum, whose doors were open during war and closed during peace.
Parents: The Primordial Version vs. Later Genealogies
The earliest Roman traditions did not give Janus any parents. He was considered a deus primigenius, a first-born or original god, who existed before the creation of the world. In this view, he was a self-generated, primordial force, often associated with chaos and the origin of the cosmos. This is the version presented in the Carmen Saliare, an ancient hymn of the Salian priests, which calls him the “creator of all things.”
Later, under the influence of Greek mythology, Roman writers attempted to fit Janus into a more structured divine family. The most common later genealogy, found in the writings of the Roman antiquarian Varro (1st century BCE) and the poet Ovid (in his Fasti), makes him the son of Caelus (Sky) and Tellus (Earth). This aligns him with the Greek Titans, as Caelus and Tellus are the Roman equivalents of Uranus and Gaia. In this version, Janus is a Titan, a sibling to Saturn (Cronus), Ops (Rhea), and the other Titans. This explains his close association with Saturn, with whom he shared a temple in the Roman Forum and with whom he is said to have ruled together during the mythical Golden Age.
Consorts and Wives: The Mother Figures
Janus is associated with several consorts, depending on the source. The most prominent is Cardea, a minor goddess of door hinges. In Ovid’s Fasti, Janus abducts Cardea and, in exchange for making her his wife, gives her power over doorways and thresholds. This makes her a perfect partner for the god of doors, as she protects the hinges and prevents evil spirits from entering.
Another consort is Venilia, a goddess of the sea and the winds. She is sometimes described as the wife of Janus and the mother of Canens, a beautiful nymph who was turned into a voice after her husband, Picus, was transformed into a woodpecker by Circe. This story is told in Ovid’s Metamorphoses.
A third, less common consort is Juturna, a goddess of fountains and springs. Some sources, including the Roman poet Virgil, call her the wife of Janus, though she is more commonly known as the sister of Turnus, the Rutulian king who fought against Aeneas.
It is important to note that these consorts are not all mentioned together in a single coherent myth. They are separate traditions, often from different poets and periods, and they serve to connect Janus to other divine figures and domains.
Children: The Offspring of Janus
Janus’s most famous child is Fons (or Fontus), the god of springs and fountains. His mother is given as Juturna in some sources, though others say his mother was Venilia. Fons was an important agricultural deity, and his festival, the Fontinalia, was celebrated on October 13th, when garlands were thrown into springs and wells. The family connection to Janus is fitting, as springs are “beginnings” of water.
Another child, as mentioned above, is Canens, the daughter of Janus and Venilia. She is a minor figure, known mainly for her tragic love story with Picus.
In some later traditions, Janus is also said to be the father of Olistene, a figure associated with the Sabine town of Olistene, but this is extremely obscure and rarely attested.
More generally, Janus was sometimes considered the father of all the Lares (household gods) or the Penates (guardians of the pantry), but this is a late and philosophical interpretation rather than a standard myth. The Roman poet Ennius (3rd century BCE) called Janus the “father of the gods,” but this was a theological statement about his primacy, not a literal genealogy.
Janus and Saturn: A Brotherly Relationship
The most significant sibling relationship in Janus’s later family tree is with Saturn. As sons of Caelus and Tellus, they are brothers. According to the myth, Saturn was overthrown by his son Jupiter (Zeus) and fled to Italy, where he was welcomed by Janus. Janus shared his kingdom with Saturn, and together they ruled during a peaceful and prosperous age, the mythical Golden Age of Latium. This story is told in Virgil’s Aeneid and Ovid’s Fasti. In gratitude, Saturn taught the Italians agriculture and civilization, and Janus learned the art of shipbuilding. This association explains why the temple of Janus in the Forum was connected to the temple of Saturn, and why the two gods were often invoked together.
Common Misconceptions and Confusions
One common misconception is that Janus is the same as the Greek god Hermes or the Roman Mercury. This is not true. While both are associated with thresholds and transitions, Hermes/Mercury is a messenger god, a psychopomp, and a god of commerce, while Janus is strictly a god of beginnings and doorways. Another confusion is between Janus and Jupiter. While both are sky gods in some sense, Janus is not a sky god; he is a god of time and space. Jupiter is the king of the gods, while Janus is a more abstract, primordial figure.
A second misconception is that Janus’s two faces represent good and evil, or past and future. While the past/future interpretation is common, the more accurate Roman view was that he looked at both the entrance and the exit of a door, or at the beginning and the end of a journey. He was the god of both sides of a threshold, not a moral judge.
Janus in Later Culture and Language
Janus’s legacy extends far beyond Roman religion. His image has been used in architecture, with the term janiform describing any two-faced depiction. The month of January is named after him, as it is the beginning of the year. The word janitor originally meant a doorkeeper, a servant of Janus. In modern times, the term “Janus-faced” is used to describe someone who is duplicitous or two-faced, though this is a departure from the original, more positive meaning of seeing both sides. The concept of a “Janus word” (a contronym, like “cleave” meaning both “to split” and “to adhere”) is also derived from his name.
Frequently Asked Questions
Who is Janus’s father?
In the earliest Roman tradition, Janus has no father; he is a primordial god. In later, Greek-influenced sources, his father is Caelus (the sky), the Roman equivalent of Uranus. This is the version given by Varro and Ovid.
Who is Janus’s wife?
Janus has no single, consistent wife. His most common consort is Cardea, the goddess of door hinges, whom he married after abducting her. Other sources name Venilia, a sea goddess, or Juturna, a fountain goddess, as his wife. These are separate traditions, not a single family.
Does Janus have any children?
Yes, the most notable child of Janus is Fons (or Fontus), the god of springs and fountains. He is also the father of Canens, a nymph, in some stories. In later philosophical interpretations, he was considered the father of the Lares and Penates, but this is not a standard myth.
Is Janus related to Saturn?
In the later Greek-influenced genealogy, Janus and Saturn are brothers, both sons of Caelus and Tellus. They are closely associated in myth, as Janus welcomed Saturn to Italy and they ruled together during the Golden Age.
Why is Janus depicted with two faces?
Janus’s two faces symbolize his ability to see the past and the future, and to look at both the entrance and the exit of a door. He is the god of beginnings and endings, and his two faces allow him to oversee all transitions. He is not a symbol of duplicity in the original Roman religion.
