From the acclaimed author of Life and Trilobite!, a fascinating geological exploration of the earth’s distant history as revealed by its natural wonders.
The face of the earth, crisscrossed by chains of mountains like the scars of old wounds, has changed and changed again over billions of years, and the testament of the remote past is all around us. In this book Richard Fortey teaches us how to read its character, laying out the dominions of the world before us. He shows how human culture and natural history–even the shape of cities–are rooted in this deep geological past.
In search of this past, Fortey takes us through the Alps, into Icelandic hot springs, down to the ocean floor, over the barren rocks of Newfoundland, into the lush ecosystems of Hawai’i, across the salt flats of Oman, and along the San Andreas Fault. On the slopes of Vesuvius, he tracks the history of the region down through the centuries?to volcanic eruptions seen by fifteenth-century Italians, the Romans, and, from striking geological evidence, even Neolithic man. As story adds to story, the recent past connects with forgotten ages long ago, then much longer ago, as he describes the movement of plates and the development of ancient continents and seas. Nothing in this book is at rest. The surface of the earth dilates and collapses; seas and mountains rise and fall; continents move.
Fortey again proves himself the ideal guide, with his superb descriptions of natural beauty, his gripping narratives, and his crystal-clear, always fascinating scientific explanations.
Here is a book to change the way we see the world.

Up and Down
It should be difficult to lose a mountain, but it happens all the time around the Bay of Naples. Mount Vesuvius slips in and out of view, sometimes looming, at other times barely visible above the lemon groves. In parts of Naples, all you see are lines of washing draped from the balconies of peeling tenements or hastily constructed apartment blocks: the mountain has apparently vanished. You can understand how it might be possible to live life in that city only half aware of the volcano on whose slopes your home is constructed, and whose whim might control your continued existence.
As you drive eastwards from the centre of the city, the packed streets give way to a chaotic patchwork of anonymous buildings, small factories, and ugly housing on three or four floors. The road traffic is relentless. Yet between the buildings there are tended fields and shaded greenhouses. In early March the almonds are in flower, delicately pink, and there are washes of bright daffodils beneath the orchard trees; you can see women gathering them for market. In the greenhouses exotic flowers such as canna lilies can be glimpsed, or ranks of potted plants destined for the supermarket trade. Oranges and lemons are everywhere. Even the meanest corner will have one or two citrus trees, fenced in and padlocked against thieves. The lemons hang down heavily, as if they were too great a burden for the thin twigs that carry them. The soil is marvellously rich: with enough water, crops would grow and grow.
This was an abundant garden in Roman times, and it still is, even if crammed between scruffy apartments and scrap-metal yards. Volcanic soil is rich in minerals; it is correspondingly generous to crops. Outside the city, Vesuvius is more of a continuous presence; the ground rises gently towards its brown summit. New buildings cling on to the side of the mountain, even high up among the low trees and broom bushes that clothe its flanks. The buildings are indistinct, however, hidden by a creamy-yellow haze of petrochemical smog spreading outwards from the frantic centre of Naples towards the mountainside. You pass a road sign to Pompeii, but from the road there is little to distinguish this suburb from any other, for all its fame.
When the road rises into the hills that abut the southern margin of the Bay of Naples, the urban sprawl begins to thin out. The orange groves are more orderly, with the trees neatly planted in rows inside cages made of makeshift wooden struts, draped over the top with nets. The slopes become much steeper than on the volcanic flanks—close terraces piled one upon the other, each banked up with a wall of pale limestone blocks. Medium-sized trees with small grey-green leaves—which appear almost silvery in the afternoon light—cling to the most precipitous terraces. These are olive trees, the definitive Mediterranean survivors, oil producers and suppliers of piquant fruit. Their deep roots can seek out the narrowest cracks. They relish limestone soils, however poor they are in comparison with volcanic loam. The villages in this part of the bay are as you would expect of regular, tourist Italy, with piazzas and ristorante-pizzerias and youths with slick hairstyles on the lookout for a fast buck. Even this long before the summer season there is opportunity for a smooth operator. You find yourself agreeing to hire a cab for a day for Â¬200 to hug the congested roads, when you could travel faster on the excellent Circumvesuviana railway for a tiny fraction of the price. Somehow, you, the visitor, have become the rich volcanic soil primed to yield a good harvest.
Near the tip of the southern peninsula, Sorrento commands a wonderful prospect of Mount Vesuvius across the entire Bay of Naples. From this steep-sided town, Vesuvius looks almost the perfect, gentle-sided cone. It could be a domestic version of Mount Fuji, the revered volcanic mountain in Japan. It can appear blue, or grey, or occasionally stand revealed in its true brown colours. On clear days Vesuvius is starkly outlined against a bright sky: a dark, heavy, almost oppressive presence. Or on a misty morning its conical summit can rise above a mere sketch or impression of the lower slopes, which are obscured in vapour, as if it were cut off from the world to make a house for the gods alone. At night, ranks of lights along Neapolitan roads twinkle incessantly. Vesuvius is often no more than a dark shape against a paler, but still Prussian blue sky. The lights might persuade you that the mountain was still in the process of eruption, with points of white illumination tracking lava flows running down the hillsides. From Sorrento, you can make of Vesuvius what you will, for within a day it will have remade itself.
The Bay of Naples is where the science of geology started. The description of the eruption of Vesuvius and the destruction of Pompeii in a.d. 79 by Pliny the Younger is probably the first clear and objective description of a geological phenomenon. No dragons were invoked, no clashes between the Titans and the gods. Pliny provided observation, not speculation.
Not quite two millennia later, in 1830, Charles Lyell was to use an illustration of columns from the so-called Temple of Serapis at Pozzuoli, north of Naples, as the frontispiece to volume 1 of the most seminal work in geology—his Principles of Geology. This book influenced the young Charles Darwin more than any other source in his formulation of evolutionary theory: so you could say that the Bay of Naples had its part to play, too, in the most important biological revolution. Everybody who was anybody in the eighteenth and nineteenth centuries visited the bay, and marvelled at its natural and archaeological phenomena. For geology—a latecomer to the pantheon of sciences—the area is the nearest thing to holy ground that there is. If you were going to choose anywhere to retrace the growth in our understanding about how the earth is constructed, what better place to begin? Where else more appropriate to explain first principles? The long intellectual journey that eventually led to plate tectonics started in this bite out of the western shin of Italy’s boot-shaped profile. A voyage around this particular bay is a pilgrimage to the foundations of comprehension about our planet.
Everything about Sorrento is rooted in the geology. The town itself is in a broad valley surrounded by limestone ranges, which flash white bluffs on the hillsides and reach the sea in nearly vertical cliffs—an incitement to dizziness for those brave enough to look straight down from the top. Seen from a distance, the roads that wind up the sides of the hills look like folded tagliatelle. Stacked blocks of the same limestone are used in the walls that underpin the terraces supporting the olive groves. In special places there are springs that spurt out fresh, cool water from underground caverns. These sources are often flanked by niches containing the statue of a saint, or of the Virgin: water is not taken for granted in these parts. There are deep ravines through the limestone hills, probably marking where caves have collapsed. The country backing the Bay of Naples is known as Campania, and the same name, Campanian, is applied to a subdivision of geological time belonging to the Cretaceous period. If you look carefully on some of the weathered surfaces of the limestones, you will see the remains of seashells that were alive in the age of the dinosaurs. I saw some obvious clams and sea urchins, belonging to extinct species, emerging from the cliffs as if they were on a bas-relief. A palaeontologist can identify the individual fossil species, and use them to calibrate the age of the rocks, since the succession of species is a measure of geological time. The implication is clear enough: in Cretaceous times all these hilly regions were beneath a shallow, warm sea. Limy muds accumulated there as sediments, and entombed the remains of the animals living on the sea floor. Time and burial hardened the muds into the tough limestones we see today. They are sedimentary rocks, subsequently uplifted to become land; earth movements then tilted them—but this is to anticipate. What one can say is that the character of the limestone hills is a product of an ancient sea.
The massive limestones continue westwards on to the island of Capri, which is a twenty-minute ferry ride from Sorrento and bounds the southern edge of the Bay of Naples. The island rises sheer from the sea, circumscribed by steep limestone cliffs, and your first thought is how could it support the smallest village, let alone a town. The town of Capri lies at the top of a vertiginous funicular railway running from the harbour. The buildings are ancient and quaint, and, naturally enough, built of the local stone. The blocks themselves are often concealed under stucco. There is a fine medieval charterhouse where the pale limestone is put to good effect in columns supporting cloisters. Almost everything else is fabricated of limestone—walls, floors, piazzas. In the bright Mediterranean light there is an overwhelming sense of whiteness; some of the villas glimpsed on the hillside have the appearance of frosted cakes tucked under umbrella pines. Only dark basalt must have been imported from Vesuvius to make the surfaces of the streets: this volcanic rock is less liable to shatter than limestone. It is not difficult to imagine the racket that iron-rimmed wheels made as they clattered over these roughly matched, large blocks. On the inner side of the island there are truly astonishing vertical limestone cliffs dropping hundreds of metres to the sea. The Roman Emperor Tiberius spent his declining years in a palace on the island, the ruins of which endure. According to the prurient accounts of his chronicler Suetonius...
