The Man of Numbers: Fibonacci’s Arithmetic Revolution
- Keith Devlin, Walker & Company, 2011.
Visitors to the Camposanto, the sacred burial ground of Pisa, so sadly damaged by Allied bombers in the Second World War, find all manner of monuments lining the walls, from Roman sarcophagi to statues of the illustrious citizens of later centuries. One of these, recently cleaned up and restored, dates from 1863 and it commemorates one of Pisa’s heroes, the mathematician Leonardo da Pisa, often known as Fibonacci (a corruption of Filius Bonacci, the son of Guiglielmo Bonacci). Although no contemporary depiction of him survives, he springs from the sculptor’s imagination with classical features, a cowled head and a long tunic. He lived from around 1170 to 1250.
Fibonacci is best known today for his famous mathematical puzzle of the breeding rabbits. Shut up a pair of rabbits in an enclosure, assume that the doe will give birth to a pair of baby rabbits every month and that these two will be up and breeding a pair a month within a month. Genetically impossible of course, but the numbers can be built up into a sequence of 1, 1, 2, 3, 5, 8, 13, 21, 34 and so on. These ‘Fibonacci’ numbers reappear in all kinds of strange places, not least as the typical number of petals in a flower.
Fibonacci was not the first to work out this sequence and Keith Devlin is not nearly as interested in it as in Fibonacci’s contribution to the commercial revolution of 13th and 14th century Italy. These years were the age of trading breakthroughs for the Italians as they captured new routes and filled them with finished grain in return for raw materials. The Venetians strengthened their position immensely after the Fourth Crusade of 1204 had allowed them to lay their hands on ports across the Mediterranean. Florence expanded fast after 1200. Yet there was a bottleneck in the commercial background. There were experts who could manipulate an abacus as quickly as one might operate a calculator today, but the final answers were always written in Roman numerals. As soon as complex issues arose, concerning how to divide profits or change money between coins of different alloys, the system just broke down. The Arab traders, on the other hand, were using a system they had adopted from India. It comprised nine numbers, each with a single-digit symbol, 8 for VIII, for instance, and, crucially, a zero, which was recognized as a number in its own right. The man who transferred the system into Italy was, Devlin argues in this entertaining book, none other than Fibonacci.
Fibonacci’s father had been posted by Pisa to the port of Bugia, in modern Algeria, where he acted as the Pisan go-between with the Berbers. Leonardo, still a boy, went with him. He must have picked up Arabic, as he tells how he talked to merchants from Egypt and Syria, and he soon grasped the superiority of their calculations and became obsessed by them. In 1202 he published a mammoth 600-page manuscript, the Liber Abaci, ‘The Book of Calculation’. It was the first time that the system had been spelled out fully and aimed directly at Italian merchants. Everything from how to divide profits and measure land to dealing in currency exchange was covered with a myriad examples to show how each kind of calculation could be made.
No copies of the 1202 manuscript survive but there are some of the second edition of 1228. By this time, Fibonacci was famous. He had been summoned to meet the formidable Holy Roman Emperor, Frederick II, who had set him three problems which he triumphantly solved. He wrote up the answers in his Liber quadratorum and this work has helped confirm him as the finest mathematician of the Middle Ages.
By the end of the 13th century there were a mass of simpler books of calculation and schools were teaching the system. In Florence in 1343, between 1,000 and 1,200 boys were working in abbaci schools. Until recently, however, historians have not been able to link Fibonacci directly to the introduction of the new system. The workbooks used by students and merchants did not appear to overlap with anything in Liber Abaci. Perhaps the system had come in at a less erudite level and slowly infiltrated the Italian cities. Yet later writers often named Fibonacci as the man who introduced arithmetic and algebra to Europe.
Devlin shows how the question has been resolved. Fibonacci must have realized that the huge manuscript of the Liber Abaci and another text he wrote for merchants on geometry, which was scarcely less large, were too much for the ordinary merchant to master. So he wrote a much shorter and simple text, now lost, and this can now be directly linked to the manuals to be found in the schools some decades later. Fibonacci was truly ‘the man of numbers’, both at a sophisticated level in algebra, but on the market floor.
This is a short book on a man about whom almost nothing is known. Fibonacci sometimes called himself Bigallo, perhaps a Tuscan dialect word for traveller, and he certainly knew his way around the cosmopolitan Mediterranean world of the 13th century. It was perhaps inevitable that the Hindu-Arabic system would have come to Italy in time—it was simply too useful in a complex trading world—but Devlin has certainly shown that Fibonacci deserves the credit for setting in all in motion. This is a readable and enjoyable book and I actually understood the maths!

The Roman Forum
- By David Watkin (Profile Books, hardback 2009; paperback June 2011)
‘Archaeology often brings to light relics—mysterious foundations, tumbled blocks, a charred sacrificial pit, the decaying stumps of dead houses—fascinating to the scholar but a stunning bore to the simple visitor.’ So wrote Dilys Powell in The Villa Ariadne. Archaeologists can be monomaniacs and their interests are often distressingly narrow. So it was with some anticipation that I took up David Watkin’s The Roman Forum, whose contentions are very clear: ‘Archaeologists have eliminated much evidence of the fascinating post-antique life of the Forum,’ and their labours have made ‘visiting parts of the Forum about as attractive as looking into the hole made in New York on 9/11.’ Ouch! These accusations run like leitmotifs throughout the book, together with the curious conspiracy theory that guidebooks are complicit; that there are things they ‘do not want us to see’.
If one works night and day to produce guidebooks, it is difficult not to get on the defensive. The Portico of the Dii Consentes doesn’t ‘turn out’ to be a modern reconstruction. Pay attention to your Blue Guide! It clearly says that it dates from 1858. There is no plot to keep visitors in the dark about the churches of San Lorenzo in Miranda or Santi Luca e Martina. They are just never, ever open. But for Watkin, everything was better in the time of Piranesi. Piranesi, he tells us, with the authority of one who knew him in a former life, recorded the Forum ‘at the last time when it was still a place of poetry, capable of inspiring great painters, writers and thinkers.’ Glum stuff, but the threnody does begin to strike a chord and the aimiable style in which the bad news is delivered soon reels you in. Watkin laments the fact that the Forum has been turned inside out: its surviving churches open away from it, no longer into it; it has been severed from the life of the city and turned into a visitors’ theme park. Up until a very few years ago, entry was free and one could use the Forum as a thoroughfare; Romans going about their daily business could loiter and linger in it. Now you have to queue to be admitted through a turnstile, custodians are bossy and offhand, and no one who is not a tourist (or an archaeologist) ever goes there. The magnificent ‘challenge of the relationship between ancient and modern’ has been obscured.
Despite the underlying crotchetiness, the book is immensely enjoyable. Watkin’s love for the Forum, his breadth of knowledge, and his wistfulness about what might have been (in a Peter Pan world) are ingenuous, impressive and infectious—a beguiling combination. The chapter on the despoliation of the Forum’s monuments in the service of the new St Peter’s is a superb read. No visitor should ever again imagine that the mere march of time had anything to do with it. What Watkin cannot admit, though, is that if archaeologists hadn’t got their hands on the Forum when they did (in the late 19th century), the urban planners certainly would have. And the challenging relationship between ancient and modern would now be as desperate a tussle there as it is at Largo Argentina.
Nevertheless, if you’re travelling to Rome—either for the first or the fiftieth time—I recommend that you get this book. Not only will it add whole layers of meaning to your visit, but it will also force to you answer the following testing questions: if archaeologists are to be banished, who will take their place (and who will pay for it)? What is the point of a desert like the Forum in the centre of a busy and increasingly cramped-feeling capital city? And whose opinion was nearer to the mark: Palladio’s, for whom the Forum offered ‘not the spectacle of ancient glory but rather the possibility of recreating it’; or Pevsner’s, for whom the Forum belongs ‘to the civilisation of Antiquity, not to what we usually mean when we speak of European civilisation’? Watkin loves the Baroque churches that were built over the ancient ruins in the 17th century. But did their architects believe they were ‘recreating’, or did they believe they were moving forward into a ‘modern’ era?

Hungarian pioneer of hand-sanitisation
How many of us today, while methodically washing our hands in the hope of staving off Covid-19, think of Ignác Semmelweis? How many of us have even heard of him? Semmelweis (1818–65) is not widely known around the world but he is a familiar name in Hungary. Budapest's medical school is named after him and he has gone down in history as the ‘saviour of mothers’ because his pioneering methods saved many women and infants from death by puerperal fever. Semmelweis’ theories were revolutionary for his time. And now, his insistence on the importance of disinfection to halt the spread of contagion has been brought once again under the spotlight as we are once again reminded of its importance. Semmelweis was ahead of the curve in his grasp of the importance of hand-washing: his hunch was borne out by significant decreases in the rate of mortality on obstetric wards under his supervision. Despite this, his idea was rejected by the established medical community, who were offended by the suggestion that a patient's death could be imputed to the medical staff's personal hygiene. What made things more difficult for Semmelweis was the fact that he was a practitioner, not a scientist. His theory could be explained as a hunch that seemed to work but he had detected nothing through a microscope that could furnish scientific explanation and proof. He never gained the reputation he deserved during his lifetime. In fact he suffered some kind of mental and emotional breakdown and began lashing out in print at the ignorance and obstinacy of the medical fraternity. In the end he was transferred to an asylum in Vienna, a move supported by his wife, who was no longer able to cope with his tantrums. He died very shortly after his admission, perhaps as a result of ill-treatment.
Semmelweis’s former home in Budapest is now a museum of the history of medicine (described in full in Blue Guide Budapest). His theory, of course, is fully recognised today. Named after him is the phenomenon known as the Semmelweis reflex, the human tendency to reject or ridicule new ideas if they fly in the face of accepted convention.
‘The Global Eye’, running at the Biblioteca Medicea Laurenziana in Florence until the end of May, is an exhibition devoted to the collection of Dutch, Spanish and Portuguese maps purchased by Cosimo III on his second journey to Holland in 1667–9 (before becoming grand-duke). A conference in November 2019, organised by the Dutch Institute in Florence, illustrated the close ties between the Dutch Republic and Cosimo III, who took a great interest in cross-cultural issues. The 82 maps (a selection of which are on view, accompanied by remarkable digital supports) represent many areas of the known world including parts of Japan, Africa, and even a unique plan dated around 1660 of ‘New Amsterdam’, when still part of the Dutch colony that a few years later was renamed New York, when the British took over. The maps were kept for a hundred years at the Villa di Castello on the outskirts of Florence, seat of the Accademia della Crusca (Cosimo III was an academician of the Crusca and their first dictionary, published in 1691, was dedicated to him in its 3rd edition). The villa itself is not generally open to the public but its garden is one of the most important of all those attached to Medici villas in the surroundings of Florence (and is fully described in Blue Guide Florence). The maps were moved for safety to the Biblioteca Laurenziana in 1921; this is the first time they have been fully studied and a catalogue raisonné provided. Visiting this fascinating small exhibition also gives you the chance to see (off the cloister of San Lorenzo) Michelangelo’s reading room with its famous vestibule, one of the most extraordinary architectural works in Florence.

With the closure today of the museums and monuments in all of Italy, those of us who visit them also for work are left wondering how such a thing could have happened in our lifetime. We suddenly find ourselves facing a drastic shortage of culture: no libraries, no theatre, no cinema. However, the very direct explanation by Prime Minister Conte late last night made it all too clear how necessary such measures have become in a country where the dreaded Coronavirus is suddenly holding us all hostage. There is no doubt that Italy has trusted leaders in Conte and President Mattarella, and the country’s medical profession are displaying all their dedication and efficiency. There is an evident preparedness in those in places of responsibility and a feeling of teamwork and pulling together in times of emergency. Millions of other Italians have merely been asked to stay at home for the time being. A measure which seems eminently sensible and which should not be a great sacrifice. Who knows how this forced restriction might even foster closer family relationships and make the homes themselves more comfortable. My garden will certainly enjoy greater attention. And with all the benefits of the internet, no one need feel cut off. There is even hope that the closure of museums and monuments will give those great institutions a chance for practicalities impossible when they are open all the time—even if only some radical cleaning, but also perhaps some reorganisation—an almost welcome pause to ‘stand back’ and contemplate themselves and their ‘mission’. I look of course on the rosy side of things, the side for those fortunate enough to have families and homes, but there is a very ugly side of this ‘shut down’, such as the situation in the overcrowded prisons, or that of people cut off from their families who are in hospitals or nursing homes, and the extremely dire economic consequences. This situation is making us all wonder about how we should live our lives in the future, about how long we can expect to enjoy ‘normal’ life in our global world.
For my involvement in the Blue Guides to Italy (Blue Guide Rome has just been published) it means I cannot set off for Venice and the Veneto for work on a volume coming up for revision: a restriction which has been imposed on me for the very first time by circumstances beyond my control (the only other time this happened to me was when I had to cut short a trip for Blue Guide Northern Italy when I was staying in Trieste the day of the terrible earthquake which hit the Friuli in 1976).
We can but hope the virus will soon be dominated with the help of everyone round the world and that we will soon return to a life as we know it, if greatly sobered by what has happened to us all.
