At the very heart of Rome lay the infamous Gates of Janus, whose ritual opening heralded the outbreak of war and whose closing celebrated the return of peace. Legend tells that during Rome’s incredible rise to power they lay open for nearly 700 years from King Numa to Emperor Augustus with but one exception. These gates of war have long captured my imagination as a piece of history that seems plucked right out of some fantasy setting. Yet they were very much real. Or were they? Today let’s dive deeper into this fascinating structure and the mystery of its patron deity Janus.
The documentary begins with a discussion of the Roman God Janus; his origins, attributes; and religious practices. We then move on to talk about the various temples and shrines of Janus located across the city of Rome with the most important ones being the Temple of Janus Geminus at the edge of the Roman forum. These likely were a part of early Roman war making traditions alongside the declarations of war and the augury of sacred chickens prior to giving battle. We discuss how myths about the Gates of War grew over the course of the Roman Republic and were later exploited by Roman Emperors such as Augustus, Nero, and Vespasian for propaganda.

At the very heart of Rome lay the infamous gates of Janus, whose ritual opening heralded the outbreak
of war and whose closing celebrated the return of peace. Legend tells that during Rome's incredible
rise to power, they lay open for nearly 700 years from King Numa to Emperor Augustus with but one
exception. These gates of war have long captured my imagination as a piece of history that seems
plucked right out of some fantasy setting, yet they were very much real. Or were they?
Today, let's dive deeper into this fascinating structure and the mystery of its patron deity,
Janus. I've derived a lot of inspiration and research for these documentaries from my growing
library. However, it's tough to get through all my books, and I often find myself looking for
ways to sate my curiosity in more on-the-fly ways. Thankfully, our sponsor Blinkist has a solution.

We would do well to start this episode by asking the question,
who is Janus? For many, his name will seem quite foreign, as we rarely hear of this god mentioned
in discussions of the Roman mythology. And yet, we've all spoken his name without knowing it.
After all, it is his name that serves as the root for the month we call January.
The enshrinement of the god's name at the start of the year should tell us something
about Janus' importance in the Roman world. Scholars investigating the matter have actually
found Janus depicted on the oldest Roman coins and have noted his presence at the top of the
oldest list of gods. In fact, in these early writings, he is often referred to as the Divum
Deus, an ancient Latin translation which means the god's god. Yet as historians have attempted
to peer into the origins of this eldest of deities, they are met with only deeper mysteries.
As best we can tell, Janus had quite deep native roots and was even said to have been the one to
have welcomed Saturn to Italian shores. He was venerated in several towns of the Tiber Valley
and had an early cult following in Rome with a prominent location on the Janiculian hill
to the west of the city named after him. Unfortunately, we know little of its beliefs
or practices. This uncertainty was actually shared by many ancient authors who also speculated on the
nature of his origins. Yet while they puzzled over such matters, they also invoked him incessantly.
Janus was called upon at the start of their prayers, received the first portion of their
sacrifices, had the first month of the year named after him, and had the first day of the year
dedicated to him with a feast day. At the same time, the arcane deity enjoyed no special priesthood
and had few temples outside of Rome. This peculiar situation led the Roman scholar
Louise Holland to aptly describe Janus' role in the Roman pantheon as being one of frustratingly
obscure prominence. It seems that Janus may have been so old that the Romans included him in their
religious rituals simply as a deeply held habit without much of an understanding as to why.
This confusion in turn led everyone, especially writers, philosophers, and cosmologists,
to attempt to stitch together or even invent some coherent concept of Janus. The end result
was a general coalescing of several key functions attributed to the god. Janus Pater, the god of
beginnings, Janus Patulchius, the god that opened doors, and Janus Clusivus, the god that closed
doors. Owing to his multi-purpose nature, he is commonly depicted with two and sometimes four
faces. In one hand, he carries a key to show his dominion over passages, and in the other, a staff
to show his authority and role as a guide. So now that we have at least a passing understanding
of Janus, we can turn to our discussion of the gates of Janus. These were a part of early
structures erected in his name. Back in the days of the Roman monarchy, several such buildings were
said to have existed. One shrine, as we have mentioned, was located atop the Janiculum Hill,
overlooking Rome, and would have been used by augurs to observe the flight of birds and for
We were told that several other small shrines existed in the area.
According to some, the most prominent of these was built by the legendary king
Numa Pompilius, who is often used to explain much of Rome's religious heritage.
Yet whatever its origins, multiple sources state that this temple of Janus was located on a street
named the Argillentum, which led from the Forum to the northeastern areas of the city.
It was a small, rectangular shrine which sheltered an ancient bronze statue of Janus,
whose odd finger placement some believed represented the 355 days of the early Roman
year. A pair of arched doorways on opposite sides of the building allowed passage through
the structure. They were barred and flanked by columns. All in all, it was a quite unique
building that was differentiated architecturally from your typical Greco-Roman temples.
Another point of distinction was the practice we alluded to at the start of the video,
that these gates of Janus also functioned as the gates of war. Let's now address this part of the
story. As should be expected, the origin of this practice is as poorly understood by us as it was
by the Romans. Some sources claim that its origins date back to the early days of Rome's kings.
This should not be wholly unexpected, as in those years, the small Latin community took many
precautions to ensure that they had the god's backing in any armed conflict. For instance,
declarations of war involved an elaborate process of walking into enemy territory,
declaring your grievances to passerbys, waiting 33 days for demands to be met, and then, if they
went unanswered, returning to enemy land to announce war with the throwing of a blood-tipped
spear in the presence of three adults. Likewise, battle itself could not be given without first
seeking approval of the sacred chickens, which were carted around with the army wherever it went.
It should be no surprise, then, that the superstitious Romans also developed a practice
involving Janus, the god of gods. Ancient authors in the late Republic like Horace, Virgil, and Ovid
offered different perspectives on the ritual. There does seem to be a consensus that the gates
of Janus stood open in war and closed in peace, but the explanation for why this was the case
differs. Some say that opening the gates in times of war would allow Janus to protect the people,
and that they could only therefore be closed when the danger had passed and peace was restored.
Another take on this idea was that when war was declared, ancient armies would ritually walk
through the shrine to augment their virtue as warriors, and when peace was concluded,
they would walk back through the shrine in the opposite direction to shed their furor
and pollution of blood guilt. In yet another interpretation,
the shrine and the power of Janus was actually meant to imprison the dark fury of war,
kind of like some evil Ganon from Zelda, which would at times break loose upon the world to
wreak havoc. Virgil has a quite evocative passage to this effect. Quote,
Whatever the case, the myth was clearly open to interpretation. This proved useful to later Roman
rulers who could leverage the story for their own agendas. Emperor Augustus, for instance,
had finally taken control of Rome after a long series of civil wars and wished to depict himself
as a stable ruler that would finally return peace to a battered land. Co-opting the old
legend of the gates of Janus would be the perfect vehicle for this message.
As a demonstration of this strategy in action, he writes boastfully in his autobiography,
quote, It was the will of our ancestors that the gateway of Janus Quirinus should be shut
when victories had secured peace by land and sea throughout the whole empire of the Roman people.
From the foundation of the city to my birth, tradition records that it was shut only twice.
But while I was the leading citizen, the Senate resolved that it should be shut on three occasions.
The prior occasions he's referring to are recorded by Livy as taking place during the
reign of Numa Pompilius around 700 BC and the consulship of Titus Manlius in 235 BC,
several years after the end of the First Punic War. It's quite the sensational claim to make
that these gates of war had remained open for almost 700 years from Numa to Augustus
with but one interruption, and I can see why the emperor was keen to play up this story.
But if we are to believe that the function of the gates served a ritual purpose in ancient
war-making akin to the spear-throwing for declaring war or the augury of chickens when
giving battle, it would seem likely that the gates were opened and closed on a far more
frequent basis. That is, if this was ever something that really happened and not some
convenient legend. Whatever the case, Augustus seized the opportunity and made a grand ceremony
of closing the gates on more occasions than ever before. According to Orosius, the first
instance took place in January of 29 BC, following Augustus' triumph over Mark Antony at Actium,
which finally concluded the civil wars. The second instance took place in 25 BC,
following a successful campaign against the Cantabrians in Iberia. And the third instance
took place in 1 BC, when the empire again stilled. I'll now read from Orosius, quote,
From that time onward they remained bolted in complete stillness for almost twelve years.
Rust even gathered upon them and it was not until Augustus was a very old man that they
were forced to be opened because of a revolt of the Athenians and the commotion raised by the
Dacians. During this period, when the gates of Janus were closed, the emperor strove,
by the maintenance of peace, to nourish and to enlarge the state which he had acquired by war,
establishing many laws to inculcate in men the habit of discipline through a reverence that was
willingly given. If true, this passage speaks to the very selective nature of what Rome called
peace and when a leader like Augustus would choose to ceremonially open or close the temple of Janus.
For example here, Orosius would have us believe that the vaunted gates of war
lay absolutely undisturbed despite the raging conflicts of the Illyrian revolt or the Germanic
wars. Yet it's perhaps the ambiguity of the ritual that made it so attractive to emperors
who could use it as a convenient piece of propaganda whenever needed. Ancient historians
for instance tell us that the gates of Janus would next be closed by Nero in 66 AD to celebrate his
general Corbulo's defeat of the Parthians, with commemorative coins even being minted to mark the
occasion. Vespasian would have his own closing ceremony in 75 AD and next we hear of this
happening again in 241 AD when Gordian III was noted to have reopened them. From this point on,
the practice seems to have run its course and largely faded away. The temple of Janus
Geminis itself was apparently moved a few times and found itself overshadowed by new structures
that now dominated the heart of Rome. In fact, to this day, archaeologists have yet to find
physical evidence of its remains in the forum. I hope you've enjoyed this deep dive into a very
niche but deeply fascinating aspect of history. To me, it's a great window into the inner workings
of the Roman world and has proved endlessly inspiring for my own fantasy world I'm building
for a Dungeons & Dragons campaign. Let me know if you'd be interested in seeing more of this
