Byzantine Empire

This article explores the complicated relationship between Venice and the Byzantine Empire. Venice grew up in the shadow of Byzantium, serving as a trade partner and faithful ally for centuries. Gradually, relations grew hostile, and Venetian ships would carry the Fourth Crusade to its fateful rendezvous with Constantinople. Visitors to San Marco can still see marble and porphyry from Constantinople, built into the walls of Venice’s preeminent church.

This video explores the land walls of Constantinople, built on the orders of Theodosius II in the mid-fifth century. They consisted of a triple line of defenses, studded with hundreds of towers and supplemented with a moat. The walls were besieged dozens of times, but were only broken in 1453 by the power of Ottoman cannons. As repaired by the Ottomans, the walls are still largely intact today.

The Byzantium and Friends podcast, hosted by Anthony Kaldellis, surveys current research in the history of the Byzantine Empire and its neighbors. In each episode, Professor Kaldellis interviews a scholar about their recent work. The cumulative effect is to reveal a world much more complex, and much more interesting, than the Byzantium found in traditional surveys. The linked episode considers the perks and pitfalls of being a Byzantine emperor.

The Arab conquests of the seventh century, which swept over Egypt, Syria, and Mesopotamia, were made possible by a catastrophic generation-long war between the Byzantine and Persian Empires. That war, in turn, was the last act in a struggle that had gone on for centuries, and shaped the whole subsequent history of the Middle East.

The iconoclast controversy, which tore Byzantium apart in the eighth and ninth centuries, centered on the use of sacred images (or icons) in Christian worship. The Iconoclasts (literally, “icon smashers”) regarded sacred images as sacrilegious; their opponents, the Iconophiles (“icon lovers”), defended icons as aids to personal devotion. After decades of struggle, the Iconophiles prevailed; their victory ensured that icons, and the brilliant mosaics inspired by them, remained a feature of Byzantine churches.

This TED-Ed video explores the mysterious cave cities of Cappadocia. Although their oldest sections may go back to the Bronze Age, most of these subterranean complexes were excavated during the Byzantine period, when the locals went underground to take shelter from Arab raiders. Monasteries were also cut into pinnacles of the local tufa, and decorated with frescoes that have often survived to the present.

A short video about the iconic Byzantine church. Still Istanbul’s most famous and, since its reconversion to a mosque, most controversial building. The recognizable dome has partially collapsed several times over the centuries, but remains a marvel of engineering. The mosaics, though fragmentary, are among the finest ever created and trace both the gradual evolution and the remarkable continuity of Byzantine art.

This is a computer reconstruction of the Byzantine capital at its apogee, just before the Fourth Crusade. Alongside detailed renderings of the Hippodrome and Hagia Sophia, it includes dozens of the imperial city’s less famous monuments, many of which can still be found in modern Istanbul. The reconstruction is a work in progress, and the Byzantium 1200 X account routinely posts updates.

The system of aqueducts that supplied Byzantine Constantinople with water had more than 500 kilometers of channels. These channels fed hundreds of cisterns. The largest were open pools (one, now drained, houses an entire modern shopping center); but the most impressive were vast covered chambers like the Basilica Cistern, still a highlight of any visit to Istanbul.

A brief survey of how Byzantine scholars changed the course of the Renaissance by introducing Classical Greek literature to Italy. These scholars and their students were responsible for translating, interpreting, and printing many of the most fundamental texts in the Western tradition. Without their efforts, the Italian Renaissance and Western thought would have been immeasurably poorer.
