The oratory at Germigny-des-Prés was built by Bishop Theodulf of Orléans in 806 as part of his palace complex within the Gallo-Roman villa in Germaniacus. Theodulf, who was also abbot of the neighboring monastery of Saint-Benoît-sur-Loire, was a Spaniard and one of the most celebrated men of letters in the Carolingian Empire court of Charlemagne. The Carolingian architecture of his palace complex at Germigny-des-Prés was in a general sense modelled on Charlemagne's Palace of Aachen. All except the oratory was destroyed by the Vikings within a century of construction.
As reconstructed by Theodulf in 806, the oratory took the form of a rough square with single apses in the middle of the north, south, and west sides, and three apses on the east side. Internally, the space took the form of a Greek cross: a high central tower filled the central bay, barrel vaults extended off in the north, south, east, and west bays, while in the corner bays there were low domes carried on squinches. This plan type was later to become standard in Byzantine architecture.
The great treasure of the church is the mosaic of the Ark of the Covenant, on the ceiling of the apse. This mosaic is the only surviving Byzantine mosaic in France, although traces of mosaics elsewhere on the roof indicate that it was part of a wider decorative scheme. The mosaic owes its preservation to being plastered over at the time of the French Revolution; it was rediscovered in the middle of the 19th century. The mosaic is one of the few remaining artworks from the period of the Iconoclasm which convulsed the Eastern Church during the 8th & 9th centuries, but which also impacted on Western Christendom. Traditionally, the place occupied by this mosaic was reserved for images of the Virgin Mary, enthroned as Queen Of Heaven, with the Christ child on her knee, and with an attendant angel on either side. These angels pointed out the divine status of the figures between them.
The artist working at Germigny (who was obviously au fait with Byzantine practice, if not actually Greek himself) has replaced the portrait of the Virgin, Mother of Christ, with an equivalent but symbolic representation. The Ark of the Covenant contains ‘manna’, the miraculous bread given from Heaven to the Israelites in the desert; this was interpreted as a prefiguration of the Virgin, who bears Christ, the Holy Bread. The mosaicist, and Théodulf d'Orléans, seem to have held a middle course, balanced between extreme iconoclasm and the partisans of images such as John of Damascus. This moderate position is exactly that which the theologians appointed by Charlemagne in the Council of Frankfurt (794) decided upon.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
