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 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.
