When the Roman army landed in Britain in AD 43, the island had no roads in the Roman sense. There were tracks worn by generations of farmers and traders, but nothing that could move a column of soldiers and its supplies quickly from one place to another. The army's first priority was therefore to build. Roads were laid out by the military, at first for the movement of troops, and only later did they become the arteries of civilian life. The network that eventually grew is often regarded as the most enduring legacy of four centuries of Roman rule.

The scale of that network was remarkable. By the end of the Roman period Britain possessed several thousand kilometres of engineered road. Watling Street, which linked the Kent coast with London and continued north-westwards, is the best known, while Ermine Street ran from London north to Lincoln and York. The Fosse Way, crossing the country diagonally from Exeter to Lincoln, is often thought to have begun as a boundary between Roman territory and the lands of unconquered peoples, though the evidence remains disputed.

Building such a road was a substantial project. Surveyors first marked out the line with instruments such as the groma, a device for setting right angles and holding a bearing. A trench was then dug along the route, and the spoil was often thrown to either side to begin the boundary ditches. Into the trench went successive layers: a foundation of large stones, broken stone sometimes bound with lime, finer gravel, and a surface of paving or compacted gravel. Not every road received all of these, for the design was adapted to local materials and to the importance of the route.

Two features mattered more than the paving itself. The first was drainage. The surface was built up in the middle so that water ran off to the sides and was carried away by ditches. A road that held water would soon break up under carts and hooves. The second was width, which varied with traffic and terrain, from tracks barely wide enough for a single cart to broad carriageways near towns and fortresses. A river crossing demanded a bridge or a ford, and a marshy stretch might be carried across on a causeway of timber and brushwood.

Travel was supported by infrastructure along the way. Milestones recorded the distance to the next significant settlement, and a number survive in Britain, though most are worn and their inscriptions incomplete. At intervals there were posting stations and inns where officials and soldiers on imperial business could change horses or spend the night. Ordinary travellers had to make their own arrangements, and there is no evidence that Britain possessed anything resembling a public coach service.

The most striking feature of the roads to the modern eye is their straightness. Popular accounts explain it by a supposed Roman dislike of curves, or by a belief that straight roads gave no cover for ambushes. Neither explanation is well supported. Roman surveyors aimed at a distant landmark and re-set their line from high ground as they advanced, so a road crossing a valley or a hill can look straight on a map while rising and falling with the land.

The network depended on the state that had created it. When Roman administration in Britain ended in the early fifth century, no authority remained to pay for repairs, and the emperors had long since stopped sending troops or funds. Bridges, the most expensive and fragile parts of the system, decayed first, since a single flood could destroy a crossing that had taken months to build. Roads stayed in use where they served local needs, but many sections were abandoned or overgrown, and some routes survived merely as boundaries between estates.

In the Middle Ages a legend grew up that four great roads had been protected by royal authority from time immemorial. They were said to be Watling Street, Ermine Street, the Fosse Way and a fourth, sometimes the Icknield Way. Historians have found no legal basis for the story, but it shows how deeply the idea of the Roman roads had entered English thought. Medieval travellers used them where convenient, and many of the kingdom's highways followed Roman lines, usually with diversions around the places the Romans had abandoned.

Knowledge of the network was recovered slowly. The sixteenth-century antiquary William Camden included Roman roads in his survey of Britain, relying on place names, visible earthworks and surviving texts. In the nineteenth and twentieth centuries better maps, ground survey and excavation allowed scholars to trace routes with far greater confidence. The system of road numbers introduced by Ivan Margary in the mid-twentieth century gave historians a common reference. Aerial survey and geophysical prospection continue to add to the total, and new stretches are still being identified.

The popular image of Roman roads remains misleading. It is often said that they were built to a single standard design, that they ran in unbroken straight lines, and that they lie beneath modern roads. None of this is quite accurate. The engineering varied enormously, the straightness is exaggerated, and although some modern roads do follow Roman ones, many do not. What remains impressive is the ambition: a network built by an army and maintained for centuries, which shaped where people in Britain would live and travel.

Double-entry bookkeeping is one of those inventions that seem, once explained, to be obvious. Every transaction is recorded twice: the same sum appears as a debit in one account and as a credit in another. Because the two sides of the ledger must always agree, the system provides a continuous check on its own accuracy. Its origins, however, are less orderly than its arithmetic. Double entry was not announced by an inventor or introduced by decree. It was worked out gradually by merchants in the trading cities of the Mediterranean, and its early history has to be reconstructed from the account books that happen to survive.

The system grew out of the problems of Italian commerce in the late Middle Ages. A merchant in Florence or Genoa might trade through agents in several cities, sell goods on credit, borrow from partners and handle coins of different values. He needed to know not only whether a voyage had made a profit but which of his partners was owed what, and how much of his own capital was committed. Records that simply listed money received and money paid could not answer such questions. The solution was to treat every person, and every category of goods, as an account with two sides, one showing what was owed to it and the other what it owed.

The mechanics are simple enough. Each transaction is entered twice, once on the left of one account and once on the right of another. Goods bought for cash increase the stock account and reduce the cash account, while a sale on credit increases what a customer owes and reduces the value of the goods held. At any moment the total of the left-hand entries must equal the total of the right-hand ones, so an arithmetical slip on one side is exposed as soon as the books are balanced. Not every error is caught, however. A mistake repeated in both entries cancels itself out, and a transaction left out altogether leaves no trace of its absence.

Reconstructing how the system developed depends on a small number of surviving books. Paper was expensive, and a merchant's ledgers were working documents, used until they fell apart. What remains is a fraction of what was written, and the survival of any particular volume is largely a matter of chance. The examples most often cited come from Italy: the ledger of the Farolfi company, Florentine merchants trading in Provence, from the end of the thirteenth century, and the accounts of the Genoese treasury from 1340. Specialists still disagree about which of these is the earliest true example of double entry.

The method reached a wider public through a printed book. In 1494 the Franciscan friar and mathematician Luca Pacioli published in Venice a large work on arithmetic, geometry and proportion which included a section on bookkeeping. Pacioli made no claim to have invented the system. He described the practice of Venetian merchants, and his account is valuable chiefly as a clear record of a technique already in use. Printing did what manuscripts could not: identical instructions reached thousands of readers, and the method could be taught outside the counting house where it had been learned.

The idea travelled with trade. Manuals appeared in Dutch, French, German and English; a Dutch manual of 1543 was followed by translations and adaptations across northern Europe, each with its own examples and its own currency. The method was also taught. In Italian cities it formed part of the practical education offered by the abacus schools, where boys intended for commerce learned arithmetic, the conversion of currencies and the keeping of accounts, alongside reading and writing. Double entry was therefore never confined to universities; it spread through apprenticeship and commercial schooling.

Nor is the system a guarantee of honesty. It exposes careless arithmetic, but a clerk who deliberately falsifies both halves of an entry leaves the books in balance. The reliability of the accounts depends on the judgement of the person who keeps them. These include the value placed on unsold stock, the rate at which equipment is written off, and whether a doubtful debt is accepted as lost. All of these are estimates, and each changes the reported profit. This is why independent examination matters, and why the audit of company accounts, required by British company law from the nineteenth century, became part of the system's history.

The significance of the technique has been argued over for more than a century. In 1902 the German sociologist Werner Sombart claimed that double-entry bookkeeping was a precondition of modern capitalism: by making it possible to calculate profit systematically, he argued, it gave entrepreneurs a rational basis for decisions. The accounting historian Basil Yamey disputed this in an essay published in 1949, pointing out that the technique was a method of recording transactions, not a cause of the trade itself, and that double entry was well established before the commercial developments Sombart sought to explain.

Few historians now accept Sombart's claim in its strong form. Many, however, would allow that a standardised way of describing a business may have made it easier to compare ventures and to raise money from outside investors. That, rather than any claim to invention, is the best case for the importance of double entry. A system devised for the partnerships of fifteenth-century Italy, refined by textbooks, taught in schools of commerce and checked by auditors, is still the basis of the financial statements published by companies today.

Search for almost any well-known photograph from the nineteenth or early twentieth century and you will find a coloured version alongside the original. Street scenes that were grey are now bright with painted shop signs; soldiers in sepia uniforms have pink cheeks. Such images are shared in enormous numbers, and they provoke strong feelings. Some viewers say that they bring the past to life. Others regard them as a kind of falsification, a prettified past invented by whoever happened to be holding the digital brush.

Colourisation is a distinct operation from restoration, although the two are often confused. Restoration is the repair of damage: removing dust and scratches, mending tears, recovering detail from a faded negative. Its aim, in principle, is to bring an image closer to what its maker produced. Colourisation adds information that the original never contained. Working from a monochrome print, the colourist must decide what colour a coat, a brick wall or a leaf actually was, and then apply it in layers, usually with the help of software. A single photograph can take many hours.

Defenders of the practice begin with an awkward point: monochrome photography is not a neutral record either. Every black-and-white image translates a colourful world into tones of grey, and the conventions governing that translation — filters, printing methods — shaped what viewers saw. Colour, on this argument, does not falsify the past so much as restore a quality of experience that the technology of the time could not capture. Marina Amaral, a Brazilian artist whose colourised photographs have been widely published, has argued that colour allows viewers to see people in the past as individuals rather than as figures in a distant story.

Nor is the process purely imaginative. Colourists research uniforms, regimental records, surviving fabric and paint, and the chemistry of early photographic processes, which recorded some colours as darker or lighter than they appeared. Where the evidence is uncertain, the choice becomes an interpretation. That, critics reply, is exactly the problem: the viewer is rarely told which parts of a coloured image rest on documentation and which on guesswork.

The argument has been loudest in film. In 2018 the director Peter Jackson released a documentary about the First World War, They Shall Not Grow Old. It used restored and colourised archive footage, with corrected speed and added sound, to make audiences feel they were watching the war as it happened. Many viewers found it extraordinarily powerful. In the 1980s, by contrast, the American broadcaster Ted Turner provoked a long dispute by colourising classic black-and-white films for television, arguing that colour would attract audiences who would not watch monochrome films. Film-makers, among them Martin Scorsese, objected that colouring a film destroyed the intentions of the people who had made it. In the United States the controversy contributed to legislation, passed in 1988, requiring altered films to be identified as such.

Behind these disputes lies a question about documents. A photograph is evidence: it was made by a particular process at a particular moment, and historians have learned to read it. A coloured photograph is a new object. It records the original image and the colourist's decisions in equal measure, and the second is invisible to anyone who does not know the first. The historian's worry is not that the colours are wrong — many are carefully researched — but that the authority of the original passes unearned to the additions. It is as though an editor were allowed to fill in the missing words of a damaged manuscript and publish the result as the manuscript.

Two recent developments have sharpened these concerns. The first is automation. Software can now colourise an image in seconds, inferring colours from patterns learned from large collections of photographs. The results can be impressive, but the program has no knowledge of the particular subject. The second is commerce. Colourised images sell books and attract clicks, and the coloured version is often the one that circulates, while the original stays in a little-visited archive. Neither development makes colourisation dishonest, but both make it easier for an interpretation to pass as a record.

Yet the choice is not between colouring everything and colouring nothing. Photographic archives have long accepted that images may be copied, cropped and reproduced for different purposes, provided the copy is identified as a copy. A colourised photograph that is clearly labelled, accompanied by the original, and honest about where the evidence is thin deceives nobody. It is a work of interpretation, and it invites the viewer to look more closely rather than less.

My own view is that colourisation is neither restoration nor forgery in itself; it becomes one or the other according to how it is presented. The claim that it brings the past to life is not empty: a face that looks familiar is harder to ignore. But it is a claim about the viewer's attention, not about the past. What matters is that the intervention is disclosed, that the original survives, and that nobody is encouraged to think they are seeing what a camera recorded.

The danger is not colour. It is the quiet substitution of an attractive guess for a difficult fact, and the willingness of audiences to accept the guess because it is easier to look at. Preserve the original, label the copy, and the argument largely disappears.
