The Byzantine Emperor Who Revolutionized Automation With His Rising Throne

When you think about Byzantine emperors, machines, rising thrones, and automation might not immediately come to mind.

We normally associate the Byzantine elite with grandiose palaces, religious debates, and heroic military campaigns. But how about mechanical lions that roared or a throne that soared towards the ceiling?

Enter Byzantine Emperor Theophilos, who reigned from 829 to 842 AD. Theophilos was a ruler whose fascination with machines and automata was so intense that, according to some accounts, he turned the imperial court in Constantinople into a spectacle of engineering marvels that became theatrical spectacles.

Byzantine Emperor Theophilos and his mechanical marvels

Because of Theophilos’s peculiar fascination, his royal court was no ordinary seat of power like others. It was a stage where innovators of the time would exhibit and trial their technological wonders, designed to dazzle visitors and assert Byzantine superiority. For example, his reception hall in the Magnaura Palace in Constantinople featured some of the most extraordinary automata of the medieval world.

Here is what a visitor to the Byzantine palaces would come across:

Golden Lions: These mechanical beasts were placed next to the imperial throne, roaring and swishing their tails thanks to exquisite hydraulic systems. They must have been of significant size to inspire awe and intimidate everyone who stood in front of the emperor. Just imagine the shock of foreign dignitaries and diplomats, witnessing these lifelike creations “guarding” the Byzantine emperor while they tried to convey their messages to the leader of the Eastern Roman Empire.

Golden Tree with Singing Birds: Another fascinating automation that adorned the imperial palace of Constantinople was a gilded tree that stood in the main hall of the Byzantine capital‘s palace. Its fake branches were filled with mechanical birds that chirped and flapped their wings, giving the illusion of real animals. This wasn’t just decoration. It was a gesture that Theophilos wanted to make, showing the extent of Byzantine engineering and sophistication and his love for technological progress and innovation.

The Rising Throne: Perhaps the pièce de résistance was Theophilos’ throne.
This engineering marvel could ascend towards the ceiling during official ceremonies, adding an element of theatrical magic to the otherwise austere throne chamber. One visitor, Liudprand of Cremona, described his amazement at seeing the emperor suddenly elevated high above the room—a feat designed to inspire awe and fear in visitors from all over.

Based on these accounts, one might argue that these devices were simply a medieval case of vanity. However, they were not just for show; they demonstrated the divine authority and technological strength that Byzantine emperors wanted to project, offering additional layers of legitimacy to the imperial family and the ruling class. In an era when rulers were often seen as God’s representatives on Earth, what better way to emphasize this than by appearing to defy gravity?

The Genius Behind the Machines

Theophilos didn’t create these marvels alone. Much of the credit goes to Leo the Mathematician, a polymath with countless talents. He was an expert in fields ranging from optics to hydraulics. Leo allegedly designed many of these automations, including the golden tree and roaring lions. His work continued a tradition dating back to Hero of Alexandria, whose treatises on water-powered devices inspired many Byzantine engineers.

Leo’s contributions went much further than imperial gimmicks. He even developed an optical telegraph system that stretched across Anatolia, enabling rapid communication across the Empire’s vast distances—an innovation that reminds us of modern signaling systems.

One might rightfully ask why Theophilos invested so heavily in these mechanical wonders. The answer lies in the Byzantine Empire’s precarious position during his reign. Surrounded by powerful rivals like the Abbasid Caliphate, Theophilos needed to bolster his personal image and his empire’s as a center of wealth, culture, and innovation.
