Constantine recognized Christianity at the beginning of the
fourth century, Theodosius established it as the Roman Empire’s offi-
cial religion at the end of the fourth century, and Justinian, in the
sixth century, proclaimed it New Rome’s only lawful religion. By that
time it was not simply the Christian religion but the Orthodox Chris-
tian doctrine that the Byzantine emperor asserted as the only permis-
sible creed for his subjects. In Orthodox Christianity, the central arti-
cle of faith is the equality of the three aspects of the Trinity of Father,
Son, and Holy Spirit (as stated in Roman Catholic, Protestant, and
Eastern Orthodox creeds today). All other versions of Christianity
were heresies, especially the Arian, which asserted that the Father and
Son were distinct entities and that the Father created the Son and
therefore Christ was not equal to God. Also classified as a heresy was
the Monophysite view that Christ had only one nature, which was di-
vine, contrary to both the Orthodox and Arian belief that Christ had
a dual divine-human nature. Justinian considered it his first duty not
only to stamp out the few surviving pagan cults but also to crush all
those who professed any Christian doctrine other than the Orthodox.
Art historians divide the history of Byzantine art into the three
periods of its greatest glory, sometimes referred to as “golden ages.”
The first, Early Byzantine, extends from the accession of Justinian in
527 to the onset oficonoclasm(the destruction of images used in re-
ligious worship) under Leo III in 726. The Middle Byzantine period
begins with the renunciation of iconoclasm in 843 and ends with the
western Crusaders’ occupation of Constantinople in 1204. Late
Byzantine corresponds to the two centuries after the Byzantines re-
captured Constantinople in 1261 until its final loss in 1453 to the
Ottoman Turks and the conversion of many churches to mosques
(see Chapter 13).
Early Byzantine Art
The emperor Justinian (r. 527–565) briefly restored much of the Ro-
man Empire’s power and extent (MAP12-1). His generals, Belisarius
and Narses, drove the Ostrogoths out of Italy, expelled the Vandals
from the African provinces, routed the Bulgars on the northern fron-
tier, and held the Sasanians at bay on the eastern borders. At home,
the emperor quelled a dangerous rebellion in 532 of political and reli-
gious factions in the city (the Nika revolt), and Orthodoxy triumphed
over the Monophysite heresy. Justinian also supervised the codifica-
tion of Roman law in a great work known as the Corpus juris civilis
(Code of Civil Law), which became the foundation of the law systems
of many modern European nations. Justinian could claim, with con-
siderable justification, to have revived the glory of “Old Rome” in
New Rome. Under Justinian, Byzantine art emerged as a recognizably
novel and distinctive style, leaving behind the uncertainties and hesi-
tations of Early Christian artistic experiment. Though still reflecting
its sources in Late Antique art, it definitively expressed, with a new in-
dependence and power of invention, the unique character of the East-
ern Christian culture centered at Constantinople.
Architecture and Mosaics
In Constantinople alone, Justinian built or restored more than 30
churches of the Orthodox faith, and his activities as builder ex-
tended throughout the Byzantine Empire. The historian of his reign,
Procopius, declared that the emperor’s ambitious building program
was an obsession that cost his subjects dearly in taxation. But his
grand monuments defined the Byzantine style in architecture for-
ever after.
