Named Mên Scryfa, ‘stone with writing’, this standing stone bears the name of an early Cornish king or leader. Its Roman capitals read Rialobrani Cunovali fili, translating as ‘Rialobranus son of Cunovalus’ and were probably placed there between around 6-8AD, though the stone itself may be prehistoric. We don’t know much about Rialobran, but he was clearly a man of some importance at a time when Cornwall had its own royalty.
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.
