Gelati is a medieval monastic complex near Kutaisi. A masterpiece of the Georgian Golden Age, Gelati is recognized by UNESCO as a World Heritage Site.
The Gelati Monastery was built in 1106 by King David IV of Georgia. It was constructed during the Byzantine empire, during which christianity was the ruling religion throughout the empire. The main church was completed in 1130 in the reign of his son and successor Demetré. Further churches were added to the monastery throughout the 13th and early 14th centuries. The monastery is richly decorated with mural paintings from the 12th to 17th centuries, as well as a 12th century mosaic in the apse of the main church, depicting the Virgin with Child flanked by archangels. Its high architectural quality, outstanding decoration, size, and clear spatial quality combine to offer a vivid expression of the artistic idiom of the architecture of the Georgian “Golden Age” and its almost completely intact surroundings allow an understanding of the intended fusion between architecture and landscape.
Gelati was not simply a monastery: it was also a centre of science and education, and the Academy established there was one of the most important centres of culture in ancient Georgia. King David gathered eminent intellectuals to his Academy such as Johannes Petritzi, a Neo-Platonic philosopher best known for his translations of Proclus, and Arsen Ikaltoeli, a learned monk, whose translations of doctrinal and polemical works were compiled into his Dogmatikon, or book of teachings, influenced by Aristotelianism. Gelati also had a scriptorium were monastic scribes copied manuscripts (although its location is not known). Among several books created there, the best known is an amply illuminated 12th century gospel, housed in the National Centre of Manuscripts.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
