The Madara Rider or Madara Horseman is a large early medieval rock relief carved on the Madara Plateau east of Shumen. The monument is dated to the very late 7th or more often the very early 8th century, during the reign of the Bulgar Khan Tervel. In 1979, the monument was listed as a UNESCO World Heritage Site.
The relief sculpture depicts a majestic horseman, approximately 23 m above ground level, carved into an almost vertical 100 m-high cliff. The sculpture is almost life-size. The horseman, facing right, is thrusting a spear into a lion lying at his horse's feet, and on the left a dog is running after the horseman. The carving of the horseman's halo and garments, as well as the bird in front of the horseman's face, are barely recognizable due to centuries of erosion and the generally poor condition of the monument.
Three partially preserved texts in Medieval Greek, carved in the rock, can be found around the image of the rider. They bear important information regarding the history of Bulgaria in the period. The oldest inscription is the work of Tervel (701–718 AD), thus it is considered that the relief was created during his rule or immediately after the Bulgars settled the region in 680–681 AD. The other inscriptions refer to the Khans Krum (802–814 AD) and Omurtag (814–831 AD), who are most likely the ones who ordered the carvings.
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.
