Among the deities of Rome, Janus holds a unique place. Unlike Jupiter, Juno or Venus, whom the Romans identified with Greek gods, Janus has no true counterpart in the Greek world. He is a profoundly Roman god, bound to what stands at the beginning and to what marks a passage. His double face, turned forwards and backwards at once, is one of the most recognisable images of antiquity and one of the richest in symbolic meaning.
The god of doors
Since antiquity the name of Janus has been linked to the Latin word ianua, "door", and to ianus, a term for covered passages and arches. Janus is the guardian of thresholds: of every door that opens and closes, of every passage from one space to another.
A door always has two sides. On one side is the outside, on the other the inside; on one side what we leave, on the other what we enter. Janus's two faces express exactly this double nature: the god looks at once at what has been and what will be, at the inside and the outside.
The god of beginnings
Janus was also the god of every beginning. In Roman prayers he was invoked first, even before Jupiter, so that every ritual act would begin under his protection. The calends, the first day of each month, were sacred to him. The name of the month of January, Ianuarius, is traditionally linked to his.
This bond between beginning and threshold is significant. Every beginning is a passage: to start something we must go through a door, leaving a previous condition behind.
The doors of the temple
In the Roman Forum stood a small shrine of Janus, known as the Ianus Geminus, with two doors. Roman tradition held that the doors stayed open in time of war and were closed only when Rome was at peace on every front. Since Rome was almost always engaged in some conflict, closing them was an extremely rare event. Augustus, in the account of his achievements, proudly recalls that under his rule the doors were closed three times.
The symbol is eloquent: the open door signals a state of movement, tension and conflict; the closed door signals completion, a balance achieved.
Janus in Ovid's Fasti
In the first book of the Fasti, the poem devoted to the Roman calendar, Ovid imagines questioning Janus directly. The god appears to him with his two faces, holding a staff and a key, and explains his own nature.
He says that he was once called Chaos, when the elements of the world were still mingled, and that his double form derives from that origin. He also explains that, like a doorkeeper sitting at the entrance of a house who sees who comes in and who goes out, he guards the gates of heaven and of the world.
Beyond the poetic play, Ovid's passage shows how educated Romans thought of Janus: not only as a god of physical doors but as a cosmic principle of opening and passage.
The symbols of Janus
| Symbol | Meaning |
|---|---|
| The two faces | the gaze towards past and future, inside and outside |
| The key | the power to open and close |
| The staff | guidance and the guarding of the way |
| The door | the threshold between two conditions |
An inner reading
Janus offers a precious image for living moments of beginning and transition. Faced with change, many people tend to look in one direction only: either they stay turned towards the past, unable to let it go, or they project themselves into the future, forgetting where they come from. Janus teaches us to hold both gazes together.
In practice this translates into a few simple gestures, especially suited to the beginning of a year, a month or a new project:
- Look back honestly. Acknowledge what you have lived through, what worked and what did not, without pointless regret.
- Look ahead clearly. State simply what you wish to begin.
- Recognise the threshold. Become aware of the moment of passage instead of letting it slip by unnoticed.
- Close what needs closing. Like the temple doors, some matters deserve to be closed so as to make room for peace.
Janus and the sense of limit
There is one last aspect to consider. The god of doors is also the god of boundaries. A door lets us pass, but it also defines a space. Without thresholds there would be neither inside nor outside, neither beginning nor end. Janus reminds us that every passage needs a limit, and that awareness of the boundary is the very condition for being able to cross it.
In short
- Janus is a distinctly Roman god, with no true Greek equivalent.
- His two faces look towards past and future, the inside and outside of every threshold.
- He was invoked first in prayers, and the calends of each month were sacred to him.
- The doors of his shrine in the Forum stayed open in war and were closed in peace.
- In inner terms he teaches us to live beginnings by holding memory and intention together.
