The panopticons of Cuba

In a few places, Bentham's vision was realised. Then it became commonplace.

In 1786, Jeremy Bentham (the philosopher and social theorist who made great inroads in the fields of ethics, jurisprudence and political philosophy, as well as being the "spiritual", if not actual, founder of UCL) visited his brother Samuel in Russia, who was working for Prince Grigory Potemkin helping administer the new provinces the country had won in the Russo-Turkish War. There, Samuel suggested to him the idea of a circular building at the core of a larger compound, by which a few guards could oversee a much bigger group of workers.

Jeremy took the idea and ran with it, eventually publishing his plans five years later under the title Panopticon; or, The Inspection-House. He laid out his idea for a great building, focusing specifically on the application of his ideas to a prison, but emphasising the flexibility with which they could apply to hospitals, schools or "mad-houses". As his brother suggested, it would be circular building, with a glass lantern in the middle where the guards would keep watch, "roughly the size of Ranaleigh [sic]", meaning the rotunda at Ranelagh Gardens in Chelsea:

But Jeremy improved his brother's idea in one crucial way. As well as allowing just a few guards to administer an entire prison, his plan involved concealing the inspectors from the view of the prisoners, "by blinds and other contrivances". The idea then is that the prisoners are forced to act as though they're being watched, even if there's no one in the watchtower at all.

In practice, this element of the idea was too cumbersome to pull off. It was one thing, with 18th and 19th century technology, to obscure where someone was looking; but it was quite another to obscure whether they were even present at all, in a building which must, to be effective, allow occupants to look out from 360 degrees.

Philosophy students, on learning about Bentham and the panopticon, tend to assume it was a thought experiment, designed to elaborate some aspect of the human psyche. It wasn't; he actually spent the better over a decade trying to get it built, before billing the government £700,000 (just under £50m in 2012 pounds) for his time. They paid him £23,000.

But the fact that Bentham's panopticon was never built doesn't mean it never existed. In fact, prisons around the world incorporated his ideas, although few of them attempted to implement the hidden-observance aspect of it, even after inventions like two-way mirrors would have made it practical to do so. The two best-known (and photographed) ones are in the Americas.

The Stateville Correctional Center in Illinois (above) has the circular building, central guard tower and stacked cells, and the Encyclopaedia of Chicago confirms the Benthamite influence. The prison itself is still open, and the roundhouse block is now used to segregate inmates from the general population, as well as holding prisoners awaiting trial or transfer.

The Presidio Modelo, a Cuban "model prison" built on an island off the country's south coast in the 1920s, was also built to a panopticon design. Tourists can now visit the prisons, which have four panopticon blocks, and a fifth where speaking was banned.

It's not hard to see why the panopticon idea has fallen out of fashion. For one thing, it was a surprisingly inefficient way of holding prisoners; the large central area required means that the jails based on the idea take up a lot of room compared to more traditional designs. And the real problems with prison discipline have never been prisoners in their cells, but in communal areas – which a panopticon design can't really help with.

But the biggest reason is obsolescence. Where technology initially prevented actual prisons from employing the continuous observance aspect, it's now standard thanks to CCTV. And not just in jails, either. For most of us in our daily lives, we're never quite sure whether anyone else is watching. Even if we aren't moving, our electronic communications could be being observed. Bentham's vision arrived, two hundred years late. And he's still owed £677,000 for his time.

Why did Britain's first road atlas take you to Aberystwyth?

Alan Ereira's new The Nine Lives of John Ogilby tells the story of a remarkable book – and its remarkable creator.

John Ogilby was a talented dancer with a bright future. Performing at White Hall Palace in February 1619, the 18-year-old leapt higher than ever to impress the watching James I and his queen. But then, crashing to the floor with a torn ligament, Ogilby never danced again. It was one of many misfortunes he overcame in a remarkable life. He went on to become a theatrical impresario, the deputy master of the revels in Ireland, a poet, a translator and a publisher of ancient classics. He even organised the public celebration of Charles II’s coronation. He was also an accomplished soldier, sailor and spy, as Alan Ereira reveals in this entertaining account of his “lives” and times.

It was a remarkable collection of lives for a man born in Scotland in 1600 and raised in poverty, the illegitimate son of an aristocrat. Yet Ogilby’s greatest achievement was to put Britain on the map when he was appointed “His Majesty’s Cosmographer and Geographick Printer” in 1674. His Britannia is the first detailed road atlas ever made. It opens with a map of England and Wales showing, he wrote, “all the principal roads actually measured and delineated”. It contains a hundred or so beautifully engraved plans of roads as winding ribbons sliced into sections. Rivers, forests, villages and bridges are included as landmarks.

Embracing the new science of measurement and experiment championed by the Royal Society, Ogilby’s surveyors used a wheel with a circumference of 16ft 6in and a handle that allowed it to be pushed along, as well as a clock face that recorded journey distances. With no universally agreed length of a mile, Ogilby chose 1,760 yards. Britannia led to the accurate measurement of almost 27,000 miles of tracks, paths and roads, though only about 7,500 are depicted in the atlas at one inch to the mile.

Britannia was published in September 1675. There were few who could afford it, at £5 (roughly £750 in today’s money), and it was too heavy to carry. Instead, travellers found their way around the country by following printed itineraries, with lists of the towns to pass through on any particular journey.

Britannia is not, as Ereira explains, an atlas of commercially useful roads of the day. The first journey is an odd one, from London to Aberystwyth, then a town of fewer than 100 houses and a ruined castle. Some of the roads chosen were no longer in use, while important routes such as those to Liverpool and Sheffield were left out.

But the choice of roads in Britannia begins to make sense as being those necessary for the royal mastery of the kingdom. The London to Aberystwyth road led to mines nearby. In the days of Charles I those mines contained lead and silver that helped the king pay his soldiers during the civil war. Britannia was a handbook, Ereira explains, for a conspiracy leading to a new kingdom under a Catholic king.

Ever since the start of the Reformation, Europe had been rumbling towards a religious war. When it came on the mainland it lasted 30 years and left millions dead. The subsequent Peace of Westphalia led to a new map of Europe, one of countries and defined frontiers instead of feudal territories with unclear borders and independent cities. England was not included in the peace but shared in its vision of separate sovereignty. This led to different results in different places. In France, the king became an all-powerful despot; in England it was the ruler who lost power as parliament emerged triumphant.

In 1670 Charles I’s son Charles II decided to throw off the restraints he had accepted as the price of his restored monarchy. He wanted to be the absolute master in his land. To achieve this, he entered into a secret treaty with the French king Louis XIV. Charles needed money, an army, allies to execute his plan, and detailed knowledge of the kingdom; Louis was willing to bankroll the venture as long as Charles converted to Catholicism. Britannia was a vital part of Charles’s strategy to assert military control: he would use it to help land and deploy the 6,000 French troops that Louis had promised him to assist his forces. The pact remained a well-kept secret for nearly a century, even though it soon fell apart when the French and British got bogged down in a war with the Dutch.

No matter. Ogilby died in September 1676 and in 1681 Charles II dissolved parliament for the last time during his reign. “Britannia provided an extraordinary grasp over the business and administration of the 399 communities that it identified in England and Wales, and the crown took a grip on them all,” Ereira writes.

In this way, the atlas played a significant part in enabling the king’s revenue to grow by one-third within a few years. No longer needing financial help from Louis, Charles ruled by divine right, exercising absolute power until his death in 1685. The lesson of Britannia was that whoever controls the map controls the world.
