“In the days of Justinian, ships around Constantinople were terrorized for over 50 years by a whale whom locals called Porphyrios, presumably from the dark-wine color of its skin.”

The angry whale sank ships and terrified others.

It was like the “Jaws” of the Roman Empire!
🧵🧵 Image
Prokopios described the beast: “the whale, which the residents of Byzantion (Constantinople) called Porphyrios…had harassed Byzantion and its surroundings for over 50 years, but not continuously, for sometimes it would disappear for long periods of time.” Image
“The Emperor Justinian made it a priority to capture the beast, but he could find no way by which to accomplish this.”

Justinian normally figured out a way to solve problems, but this one proved too much. Image
The whale inspired fear, “forcing ships to make great detours from their course.” The thing allegedly even hunted dolphins and ate them!

However, eventually the whale met its end chasing those dolphins! Image
“One day it began to chase and eat some dolphins, but it ran aground in the mud and got stuck. The locals came out with axes and cut it into to pieces. Some of the locals began to eat it on the spot; while others took away their portion to cure (Prokopios, Wars 7.29.16).” Image
The whale was very large. The people dragged it out of the mud with ropes after having attacked the whale with axes.

Then the locals measured it - “placing it on wagons, they found its length to be more than thirty cubits and its width ten cubits.” Image
One can imagine a whale would have been quite the intimidating threat for sailors, even anxiety that it might occur would be a fear. Perhaps rumors circulated at the ports, for example.

Liquid fire was a legendary Eastern Roman weapon that saved Constantinople and incinerated enemy fleets!

In the 15th century John Chortasmenos read old histories and wondered:

“Where is this Greek Fire now?”

It was long gone, but when and how did they lose this weapon?

🧵🧵Image
The fearsome substance had quite a reputation. When the Crusaders attacked Constantinople in 1204 they seemed to prepare for it to be deployed against them, but they did not have to face it.

Instead, it seems the technology at some point had already been lost forever. Image
“According to Niketas(Choniates), the Venetians covered their galleys with ox hides as protection against fire, almost as though they expected to have to counter Greek Fire; however, neither he nor any Latin chronicler mentioned it actually being used against them.”

It was lost! Image

THE BEACONS ARE LIT! ANATOLIA CALLS FOR AID!

During the 9th century the Eastern Roman Empire deployed a beacon system allowing it to send warnings of danger from the border with the Arabs to Constantinople in rapid time.

How did this “Lord of the Rings” style system work?

🧵🧵Image
This system was likely “created by Leo the Mathematician, who devised a code for the interpretation of signals, and had two identical water clocks made for the terminal stations. His work took account of the difference in longitude and the time the signal needed for transmission” Image
“Signals were flashed from Loulon north of the Cilician Gates, where the Arabs would be first observed, to Argos on the Hasan Dag in Cappadocia, thence by a series of unidentified stations to Mokilos above Pylai, then to Mt. Auxentios and the imperial palace… about 450 miles.” Image

In the 9th century the Emirate of Crete was raiding and enslaving people across the Aegean

One Roman admiral stepped up, Niketas Ooryphas!

He defeated the Saracens, taking harsh measures to ensure “they would think twice before sending an expedition against the Roman Empire.”🧵Image
Niketas had to deal with a raid heading towards the Sea of Marmara sent by the Emirate of Crete, a state which constantly terrorized the Aegean with raids targeting loot and slaves.

In this case the enemy “had advanced as far as the Proconnesos of the Hellespont.”Image
The Arab raiders “enslaved the people, looting and burning” as they went.

However, eventually they were “met at the mouth of the Aegean, near Kardia, by the patrician Niketas Ooryphas, droungarios of the admiralty now commanding the Roman fleet.”Image

Even after Constantinople fell in 1453, some Christian resistance persisted in the Aegean against Ottoman expansion!

The Greek island of Rhodes was Sultan Mehmed’s next target in 1480.

However, the Knights Hospitaller bravely defended their fortress against Ottoman forces!🧵🧵 Image
Sultan Mehmed II, the famous conqueror of Constantinople, had systematically removed many Christian powers.

The Genoese lost Galata, Roman remnant states in Trebizond and the Morea were extinguished. The southern Balkans were secure under Turkish rule.

But many islands weren’t! Image
One obstacle for the Turks was the Order of the Knight’s Hospitaller, Crusaders whom had seized the island of Rhodes from the collapsing Roman Empire back in the 14th century.

The Ottomans intended to end this issue. Mehmed’s targets usually didn’t fare well.

Battle was coming!

The “Venice” of Late Antiquity

“Ravenna was built on sandbanks and wooden piles, with bridges over the many canals that flowed around and into the city, just like Venice in later centuries.”

How and why did the city of Ravenna became a Roman capital? 🧵🧵Image
Ravenna is “situated as not to be easily approached either by ships or a land army...A army cannot approach it at all; for the river Po ... and other navigable rivers together with some marshes, encircle it on all sides and so cause the city to be surrounded by water”

-ProkopiosImage
Ravenna had all the necessary ingredients of a Roman capital city - “municipal buildings, facilities for public entertainment, temples and, eventually, churches - scattered across the harshly land seperateing the Padenna and Lamisa tributaries of the Po.” Image

What was it like to enter Constantinople through the land walls and make your way through the Queen of Cities?

“Perhaps the best way to appreciate the impact that Constantinople would have had is to follow the path that would have been taken by a visitor.”

A tour of the city 🧵Image
“Most visitors…came by land, and their first inkling of the city beyond would come when the towers of immense defensive Land Walls that stretched from the Golden Horn to the Sea of Marmara came into view and barred any further progress.” Image
They had to apply to enter through one of the gates.

“The Golden Gate, an impressive structure topped with two bronze elephants and covered in classical reliefs from an earlier age.”

It “was reserved for emperors returning from victorious campaigns and normally remained closed” Image
