Mosaic programs in the Basilica of San Vitale (Ravenna) culminated in the famous imperial panels of Justinian I and Empress Theodora, a landmark of early Byzantine state-and-church imagery and court iconography in mosaic.
The fortress-monastery at Mount Sinai was constructed under Justinian I (mid-6th century), becoming a crucial sanctuary for early panel icons (including encaustic works) and a rare environment where icons survived later periods of icon destruction elsewhere in the empire.
Emperor Leo III initiated formal imperial measures against sacred images (traditionally dated to the 730s), setting off the first major wave of Byzantine Iconoclasm that reshaped church decoration, including the suppression of figural mosaics and icons in many contexts.
The Second Council of Nicaea reaffirmed the legitimacy of venerating icons, formally restoring iconophile doctrine after the first iconoclast phase. This decision provided a theological basis for renewed monumental image programs in mosaic and panel painting.
In 815, Emperor Leo V revived iconoclast policy, reopening conflicts over sacred images and again affecting the production and display of icons and figural church decoration.
A council in Constantinople (843) confirmed icon veneration; the restoration was celebrated liturgically as the Triumph of Orthodoxy, ending the iconoclast controversy as imperial policy and enabling sustained revival of icon production and mosaic programs.
After the end of Iconoclasm, Hagia Sophia received a monumental apse mosaic of the Theotokos with the Christ Child (dated to 867), a high-profile statement of restored image veneration at the empire’s premier church.
The katholikon at Hosios Loukas (Greece) received its celebrated Middle Byzantine decoration—mosaics on gold ground integrated with marble revetment—representing the mature post-Iconoclasm church interior program.
The imperial foundation of Nea Moni (Chios) was inaugurated (1049) under Constantine IX, anchoring one of the major 11th-century mosaic ensembles in Greece and illustrating the close link between imperial patronage and monumental mosaic programs.
The mosaic program at Daphni Monastery (near Athens), renowned for its dome Pantocrator and sophisticated 11th-century style, exemplifies the “second golden age” of Middle Byzantine mosaic decoration recognized by UNESCO for this monastic group.
In Hagia Sophia’s upper galleries, the Deësis mosaic (Christ flanked by the Virgin and John the Baptist) was produced around 1261, associated with the end of Latin occupation and the restoration of Byzantine rule—an iconic work of the early Palaiologan period’s heightened naturalism.
The parekklesion (side chapel) of the Pammakaristos Church in Constantinople, added in the early 14th century (shortly after 1310), received an important mosaic program that reflects elite commemorative patronage and Palaiologan-era iconography.
The Chora (Kariye) Church’s extensive narrative mosaics—including major cycles such as the Life of the Virgin—were produced ca. 1315–1321 as part of Theodore Metochites’ restoration, a defining achievement of late Byzantine monumental icon programs.
