The wind pushes, and the steppe moves before it.
0:06
Clouds sweep overhead, the short grass bends, and the only fixed points in the rolling landscape
0:13
are a snowcapped mountain and the distant silhouette of Mren cathedral.
0:19
As you walk a lonely hour from the nearest village, and wind whirls dust through the
0:23
whispering grass, details of the cathedral become visible: the conical tower, a lichen-spotted
0:30
roof, empty windows.
0:32
At last, clambering over the ruins that surround the church, you step inside.
0:39
Light spills through a collapsed wall, illuminating a floor torn apart by treasure hunters.

0:44
Faded figures of Christ and the prophets gaze down on the naked apse.
0:51
Over one of the side doors is a sculpted panel.
0:54
Although the stone is weathered, two figures are still visible, standing on either side
0:59
of a crucifix.
1:00
It’s far from obvious now, but fourteen centuries ago, when the church was new, few
1:07
would have mistaken its meaning.
1:09
This relief almost certainly commemorates March 21, 630, the day the Roman emperor Heraclius
1:17
formally returned the True Cross, the most sacred of all Christian relics, to the Church
1:22
of the Holy Sepulcher in Jerusalem.
1:26
The restoration of the True Cross put a symbolic close to a war that had lasted a generation

and come very close to destroying the Roman Empire.
1:34
Heraclius had won that war with a series of daring campaigns launched from the high steppes
1:40
of Armenia – not far from the place where, just after the war’s end, an Armenian prince
1:45
built Mren Cathedral to celebrate his part in the victory.
1:50
Mren Cathedral was built near the ancient world’s most contested boundary: the frontier
1:56
between the Roman and Persian empires.
1:59
For seven centuries, beginning with the great conquests of Pompey, the eastern edge of the
2:04
Roman world ran from the Armenian plateau to the Arabian Desert.
2:09
The most hotly contested part of this frontier was always the center, where it bisected the
2:14
fertile plains of northern Mesopotamia.
2:16
But in times of war, any section of the thousand-mile border might become the center of a major
2:23
conflict.
2:25
Many of the wars between the Persians and Romans devolved into sieges of the fortress-cities
2:30
guarding the Mesopotamian frontier.
2:32
Otherwise, conflicts tended to consist of raids and counter-raids, back and forth, century
2:39
after century, none really changing, or really expected to change, a balance of power that
2:46
seemed settled in the natural order of things.
2:49
Then, at the end of the sixth century, that balance was shattered forever.
2:54
Before we begin the story of the cataclysmic final war between Rome and Persia, a word

about this video’s sponsor.
3:03
Babbel is a language learning app that uses short interactive lessons based in real-world
3:10
conversations.
3:11
I’ve spent quite a bit of time in Turkey, and I used to be fairly conversant in Turkish.
3:17
But since I’ve gotten more than a little rusty in the years since my last visit, I
3:22
decided to use Babbel to refresh my conversation skills.
3:27
Babbel offers a variety of Turkish courses, tailored for different interests and needs.
3:33
I decided to focus on the “Turkish for your vacation” course, where I reviewed such
3:38
useful phrases as “Müze açık mı?”
3:41
(Is the museum open?) and “otobüs dolu” (the bus is full).

Back to the Roman frontier.
4:07
One September morning in the year 590, the Roman sentries at Circesium, a border fort
4:12
in northern Mesopotamia, were startled to see a group of Persians in court dress galloping
4:18
from the east.
4:19
The riders drew up beneath the gates; and their leader, a man of about twenty, called
4:24
up in passable Greek, asking for an audience with the commanding officer.
4:29
When the gates were opened, the young Persian revealed that he was Khosrow, the newly-crowned
4:33
King of Persia, and that he was fleeing a palace coup.
4:37
The commander at Circesium sent the refugee king and his retainers to general headquarters
4:43
in nearby Hierapolis.
4:46
From there, Khosrow dispatched a delegation to Emperor Maurice, promising generous territorial
4:52
concessions in exchange for Roman aid.
4:55
Maurice agreed; and the following spring, Roman forces flooded into Persia, seizing
5:01
the capital and decisively defeating the rebels.
5:04
Khosrow was re-installed as king.
5:08
Then, in 602, Maurice was deposed in a mutiny.
5:13
The usurper, Phocas, executed the emperor and his six sons, displaying their heads in
5:18
Constantinople’s main forum.
5:21
There were rumors, however, that Theodosius, Maurice’s eldest son and heir, had escaped
5:27
by bribing the executioner; and a few weeks later, a man claiming to be Theodosius appeared
5:34
at the Persian court.
5:37
certainly aware that the real Theodosius was dead, Khosrow launched a massive attack on
5:42
the Roman frontier, ostensibly to restore the rightful emperor.
5:47
In a series of grueling sieges, the Persians seized one after another of the Mesopotamian
5:53
fortress-cities, breaking through the inmost line of defenses just as the Romans plunged
5:58
into a civil war.
5:59
The Roman governor of Africa had raised the standard of rebellion against Phocas, and
6:04
sent a fleet under his son Heraclius to Constantinople.
6:09
After gaining the allegiance of Egypt, Heraclius sailed on to the capital and personally beheaded
6:14
Phocas.
6:16
He was crowned emperor shortly afterward.
6:19
Taking advantage of the chaos at Constantinople, Khosrow occupied territory far inside the
6:25
old frontier.
6:26
Antioch fell, followed by Damascus.
6:30
Heraclius, who had been trying to shore up the collapsing Danube frontier, marched to
6:35
Syria at the head of the largest army he could scrape together.
6:39
His ill-trained troops, however, were defeated, and he was forced to retreat.
6:45
In 614, after a brief siege, the Persians took Jerusalem, burned most of the city’s
6:51
churches, and captured the True Cross.
6:54
The loss of this relic, revered throughout the Empire as the instrument of Christ’s
6:59
Passion, was a serious blow to Roman morale, especially after the Cross was carried back
7:04
to the Persian capital, and installed in the private chapel of Khosrow’s Christian wife
7:09
Shirin.
7:11
As one Persian army began to conquer Egypt, another marched across Anatolia to the Asian
7:16
suburbs of Constantinople.
7:19
Desperate to end the war, Heraclius attempted to negotiate with Khosrow, promising dramatic
7:23
territorial concessions if the Persian forces would withdraw.
7:27
By this point, however, Khosrow had achieved too much to return to the old status quo.
7:34
Syria, Palestine, and Egypt were annexed to the Persian Empire, and a Persian camp was
7:40
established across the Bosporus from Constantinople.
7:44
In the meantime, the Avars and Slavs swept over the Danube, and occupied most of the
7:49
Balkans and Greece.
7:52
Little remained of the Roman Empire.
7:54
Heraclius, however, continued to fight.
7:58
Melting down the gold and silver plate of Constantinople’s churches to pay his soldiers,
8:04
he reorganized Rome’s last army, supplementing the usual heavy infantry with brigades of
8:09
archers and light cavalry for fast-moving skirmishes.
8:14
With this force, he began to attack the Persian armies in Anatolia, and scored a series of
8:19
minor victories.
8:20
After outlasting a Persian counter-attack on Constantinople, he made the bold decision
8:26
to base his army in and around Armenia, where he could disrupt enemy troop movements and
8:32
launch raids into the Persian heartland.
8:35
This strategy proved remarkably successful.
8:39
From bases in Armenia and the Caucuses, Heraclius attacked cities throughout northern Mesopotamia,
8:45
forcing the Persians to withdraw troops from the conquered territories and engage with
8:49
him.
8:50
After Heraclius inflicted serious defeats on Persia’s two best generals, Khosrow ordered
8:56
a massive assault on Constantinople, knowing that the Roman Empire would collapse if the
9:01
city was taken.
9:03
Heraclius managed to crush one of the Persian armies marching on the capital.
9:08
The other, however, eluded him, and joined a colossal force of Avars and Slavs in a coordinated
9:15
attack on the Roman capital.
9:17
The Roman navy managed to keep the Persians on the Asian side of the Bosporus, sinking
9:22
the fleet of dugout canoes the Avars sent to bring their allies across.
9:28
On the European side, 80,000 men hurled themselves against the fortifications.
9:33
But the city’s towering triple walls held, and every assault was repulsed.
9:39
After six weeks, the Slavs and Avars retreated in disorder, and the Persians withdrew to
9:44
their camp.
9:46
Enraged, Khosrow ordered the execution of Shahrbaraz, the Persian general responsible
9:51
for coordinating the siege.
9:53
Heraclius, however, managed to intercept the messenger, and forwarded the death warrant
9:58
to Shahrbaraz with his compliments, suggesting that the Persian general might find it expedient
10:05
to switch sides.
10:07
Shahrbaraz did so, and withdrew his entire army to Syria.
10:12
Having neutralized Khosrow’s best general, Heraclius resumed his offensive, allying himself
10:18
with the nomadic Khazars to ravage Persian territory.
10:22
On a foggy morning in December 627, near the ruins of Nineveh, he encountered the largest
10:28
remaining Persian army.
10:30
The ensuing battle was savage – supposedly, Heraclius killed the enemy general in single
10:36
combat – but the Romans were victorious.
10:40
The next day, Heraclius marched on the now undefended Persian capital.
10:45
When Khosrow refused to negotiate a peace, he was deposed and executed by his nobles,
10:51
who immediately began talks to end the war.
10:54
The frontier was restored to its original place, all Persian troops were recalled home,
10:59
and Heraclius began a triumphal march back to Constantinople.
11:04
Along the way, he stopped in Armenia, where he spent a few weeks receiving the submission
11:09
of the local nobles.
11:10
As he marched homeward, Heraclius passed within a few miles of the newly-dug foundations of
11:16
Mren Cathedral, which one of the greatest Armenian princes had just begun to construct.
11:22
Although the design of this new church borrowed from both Persian and Roman architectural
11:27
styles, its dome was likely inspired by Hagia Sophia.
11:32
It was at that church, in September 629, that Heraclius celebrated his victory over the
11:38
Persians, the True Cross suspended on gilded chains over the high altar.
11:43
The following year, during a tour of the territories recovered from the Persians, Heraclius restored
11:48
the relic to the Church of the Holy Sepulcher in Jerusalem.
11:53
Back in Armenia, Heraclius’ restoration of the True Cross was chosen as the subject
11:57
of the relief over the north door of Mren Cathedral.
12:01
As a sign of his humility before God, the emperor was shown without crown or scepter.
12:07
The warhorse standing a short distance from him, however, reminds the viewer of Heraclius’
12:12
campaign to save the Empire, concluded only a few years before.
12:17
As the cathedral rose, the Roman Empire was at peace.
12:21
But before construction was completed, and before Rome or Persia could rebuild their
12:26
militaries, a new threat emerged.
12:30
Fast-moving armies of Arab horsemen, unified and fired by the new religion of Islam, tore
12:35
through the eastern frontier, and swiftly conquered Syria, Palestine, and Egypt.
12:41
By the time Mren cathedral was completed, around 640, the world Heraclius had fought
12:46
so hard to restore was vanishing.
12:49
The Persian Empire would disintegrate within a decade.
12:52
And although the Roman Empire would survive, it would emerge from ordeal much smaller and
12:58
profoundly changed.
13:00
In this sense, the years in which Mren Cathedral was constructed mark the end of the antique
13:05
world, and the beginning of a new and very different era.
13:10
Through the ensuing centuries, as Arab and Byzantine raiding parties passed back and
13:15
forth to the south, a town grew up around Mren cathedral; but then borders shifted,
13:21
and trade routes moved, and the town sank back into the steppes.
13:26
Six hundred years of abandonment have drawn the cathedral, brick by brick, down to the
13:31
whispering grass.
13:33
Birds call in the dome, and the sun shines through the collapsing walls as the wind pushes,
13:39
and the steppe moves before it.
