The Wall: The Symbolism of the Limit
A wall says two things at once. It says "this is inside," and it says "that is outside." It protects the garden and it shuts the traveler out. It keeps the city safe and it makes the city a prison for those who cannot leave.
Few human works are as old, and few have been so loaded with feeling. From the first mud-brick circuit around a village to the great frontier works of empires, the wall has been the plainest way to draw a line in the world, and the stories about it show how people feel about lines.
The City Behind the Wall
The oldest known walled settlements go back to the early Neolithic. The ruins of Jericho include a massive stone wall and a tower, dated to roughly nine thousand years ago, though scholars still argue about whether it was built for defense, flood control or both.
Cities of Mesopotamia, the Indus Valley, Greece and China were typically ringed with walls, and the word for "city" in many languages is tied to the word for "enclosure."
The Greek poets told that the walls of Troy were raised by gods, Poseidon and Apollo, in the service of King Laomedon. The tale hints that a city's wall was thought to be more than masonry: it was a sacred promise of safety.
Romulus, Remus and the Sacred Line
The founding of Rome gives a famous story about the force of a boundary. According to Livy and later writers, Romulus plowed a furrow to mark the future limit of the city and raised a low wall. His twin brother Remus, in mockery, leapt over it, and Romulus killed him, saying that so would die anyone who crossed his walls.
The tale is legend, but it shows how seriously the Romans took the idea. The sacred boundary of a city, the pomerium, was a ritual line, and there was a god of boundaries, Terminus, whose stones no one could move.
The Hebrew Bible has the opposite story: a wall that falls. In the book of Joshua, the Israelites march around Jericho once a day for six days and seven times on the seventh, with priests blowing trumpets, and the wall collapses. The tale celebrates the fall of a barrier by divine help, and its imagery of "walls coming down" has lasted ever since.
The Wall as Frontier
Some of the greatest human works are frontier walls. In Britain, the Emperor Hadrian ordered a wall built across the north of the province around 122 CE, stretching about 117 kilometers (73 miles) from coast to coast, with forts and watchtowers.
The Great Wall of China is actually a series of walls built and rebuilt over many centuries by different states and dynasties, and the best-known stone and brick sections date mainly from the Ming period.
Such walls served many uses, from defense to the control of trade and taxation. They also marked the edge of what a state considered its civilization. The modern Berlin Wall, built in 1961 and opened in 1989, showed the darker side: a wall turned inward to keep people in.
The Limit in Gnostic Thought
In the Gnostic system attributed to Valentinus, the Greek word Horos, meaning "limit" or "boundary," is the name of a being who stands at the edge of the divine fullness, the Pleroma. According to the critic Irenaeus, who reports the system in his work against heresies, this Limit keeps what is outside from entering and holds the divine realm in order.
He is also called by other names, among them Cross. The figure is a reminder that even ideas about the highest things used the language of walls.
The Enclosed Garden
The wall that protects can also shelter. The Song of Songs speaks of a bride as "a garden locked," and medieval art developed the theme of the hortus conclusus, the enclosed garden, in which the Virgin Mary sits among flowers behind a low wall.
Here the barrier does not threaten but cherishes. Monasteries and cloisters took the same form, with a high outer wall and a quiet garden within.
The American poet Robert Frost, in his 1914 poem "Mending Wall," gives voice to two neighbors who repair a wall every spring. One of them says that "good fences make good neighbors." The other wonders what he is walling in or out. The poem leaves the question open, and it is still the best question to ask of any boundary.
A Word of Care
Personal walls, the kind built around the self, can become harmful when they shut out all help. If you feel cut off from others for long periods, speaking with a friend or a counselor is a gentle way to open a door without taking the wall down all at once.
Closing
Every wall is an argument about who belongs where. The stories of Rome, Jericho, Troy and the enclosed garden show that it can protect, divide, imprison or shelter, depending on who stands on which side. The oldest wisdom about walls may be the simplest: before building or breaking one, ask what it is for.
