The Prometheans by Max Adams


The book is about two generations who made a huge impact on Britain. Max Adams calls them "Prometheans" on the grounds that they stole the future from the gods, as Prometheus stole fire from the gods. That's as far as the analogy goes - the men of the early 18th C were not punished for their presumptions. Both the Stephensons were remarkably gifted, so were Humphrey Davy and Michael Faraday. So were both the Brunels, although the father had the edge as he was a true visionary. Charles Babbage was a visionary too, (he is mainly famous for inventing the "difference engine" or mechanical calculator), and wrote about how industry is organised and managed, and was sociable as well as inventive. John Martin, the massively talented painter of enormous dramatic scenes, wanted to join the practical activities of the scientific community with which he mixed by improving the drains and taking away the dreadful sewage of London, and even envisaged the Underground railway (circle line). 

One of the threads of this history is a biography of the Martin brothers, of whom the youngest, John, was (as mentioned above) a painter of apocalyptic landscapes of the early nineteenth century. Some of his works can be seen in the Tate gallery and they are still thrilling to look at, with lightning, explosions, fires and huge mountains! You can buy reproductions of them at All posters and Wayfair; so I suppose he is still popular although you would need to buy a really large poster to get the full effect of his works.


Like the German Caspar Friedrich, he painted marvellous scenes of nature, but man's place amongst it is not contemplative or inspired, but afraid, or awed, and helpless. His scenes have inspired the apocalyptic effects in a number of films. He came from a poor Northern background (the same town as my mother; I wish I had told her that when we first saw his pictures in the Tate) and his mother held frightening religious beliefs, which particularly affected his brother Jonathan, who was on the edge of crazy all his life.
Whether Martin was a millenarian or not is still the subject of dispute. Certainly his eccentric brothers – collectively known as the “Mad Martins” – were, and indeed his older brother Jonathan was also genuinely mad, setting fire to York Minster and subsequently being institutionalised in St Luke’s Hospital for Lunatics. Ruthven Todd, Martin’s biographer, unearthed an advertisement from 1848 for a book on the British Israelites (a fringe group of millenarians) “with designs by John Martin”, though neither the book nor any other link has been found. On the other hand, Martin’s friend Ralph Thomas described him as a “thorough Deist” – that is someone who saw proof of God’s existence not in scripture, but in the marvellous workings of the natural world. Martin also devoted the majority of the last two decades of his life to schemes for the betterment of London, particularly its smelly and polluted river;  he made no connection in these projects to his own religious beliefs. Nor, apparently, did he disapprove of London’s industrial modernity, but thought it “the most wealthy, civilised, and enterprising city in the world”.
Whatever Martin’s private convictions – or lack of them – there was undoubtedly something in the air. Random occurrences took on portentous significance. When, in 1815, a giant volcano erupted in Indonesia, the dust cloud obliterated the following year’s entire summer, and street hawkers sold pamphlets announcing the death of the sun. Percy Bysshe Shelley and his teenage mistress Mary fled London for Geneva where they stayed with Byron (much of Mary’s novel Frankenstein; or, The Modern Prometheus was written there). Also, in 1816, Martin exhibited Joshua commanding the sun to stand still upon Gibeon at the Royal Academy. Although received dubiously by the Academy’s members, the painting was a hit among the viewing public, perhaps because its depiction of the prophet, marshalling with raised arms the elemental forces that swirled about him, was a tonic for the helplessness most people felt at the time. Martin became renowned for giving his public what they wanted, and was often derided because of it. He was an accomplished printmaker, and his affordable mezzotints hung in homes all around the world. But he was never elected as a Royal Academician, and was condescended to by the artistic establishment. (John Constable called him a “painter of pantomimes”.) By and large, he rose above such sneers. There is evidence, however, that the ambitious working-class artist was conflicted about his social standing: some, such as the painter Charles Leslie whom Martin once embarrassed at a concert by hissing throughout the National Anthem, saw him as something of a radical. This was despite Martin’s close friendship with Prince Leopold of Saxe-Coburg-Gotha and even Prince Albert, whom he reportedly received at his house in dressing gown and slippers.
Have to interrupt here and say Martin probably didn't want to sing "God save the King" because there was nothing good to say about George IV, who was vain and silly, but the  Saxe-Coburg-Gothas mentioned were men of sense. Prince Leopold was planted on the throne of Belgium and made a success of it.
Part of his popularity might be attributed to his skill at sanitising the decadent and raw products of Romantic culture. He absorbed Edmund Burke’s theory of the Sublime – that sensation of delightful terror elicited by vast, rugged vistas – and tailored it for mainstream tastes. J.M.W. Turner, fourteen years Martin’s senior and an acquaintance, though hardly a friend, achieved the critical recognition that the younger artist craved. The two men were markedly different: Martin was, by all accounts, a charismatic conversationalist and a snappy dresser; the reclusive Turner, according to Martin’s son Leopold, was “untidy; a sloven and unwashed”.

Another of John Martin's brother's was called William, and he was an inventor, but being a dfficult character he never received credit for any of his inventions, although one was a miners' safety lamp much better than Davy's. 

In London, John Martin and his wife Susan made friends with all the notable scientists of the time: Humphrey Davy, Michael Faraday, Wollaston, Babbage, and Marc Brunel, Isambard's father. Charles Wheatstone, who eventually invented the electric telegraph (but not Morse code) was one of the friends. I don't know if they knew other notable engineers, for example, John Rennie. They held parties and loved conversation, chess and cards. 

Here I am, thinking still about the Brunels and the tunnel under the Thames. In the National Archives at Kew I found the responses to Isambard's invitation to dinner in the tunnel in November 1827. It must have been cold! Oh well, perhaps they all had woolly underwear and good coats on. Amongst those who wrote apologies were Michael Faraday and John Martin. Faraday said he was away and never got the invitation but he would have loved to have gone. Martin said a friend arrived and he couldn't come. I should have got those letters copied because it's remarkable to see the writing. Strange to think that Brunel kept those letters somewhere in his files all his life. The occasion was his first formal dinner, and the friends he invited included these notables. He was delighted that Admiral Codrington's son - also a naval officer - accepted his invitation. Isambard had a bit of a crush on the navy, although when you think of the size and the importance of the navy at that time, perhaps that's the wrong way of describing it. Isambard was impressed by the navy. That's better. 

Other Prometheans whose activities are described are Shelley, Caroline Norton, William Godwin, (Shelley's father-in-law), Henry Brougham and the Hunts - political radicals who spoke in favour of universal manhood suffrage - these were also John Martin's politics. Marc Brunel, for one, would not have agreed with this radical stance in politics, as he had a fear of mob violence that came from his experience of the French revolution. Isambard was instrumental in putting down the Bristol riots of 1831 - he had himself enrolled as a temporary constable.

The trouble is, none of these people considered themselves Promethean, this is a theme that the author has hit upon, and the book becomes somewhat ridiculous when the author suggests that Prometheanism was a conscious choice or even a religious sect. Adams tells the story of the Swing Riots of 1830 thus:


 "At the end of August threshing machines, always seen as a threat to employment in the southern counties, began to be destroyed. It was the start of what became known as the Swing Riots, a wave of incendiary attacks and riots across southern England lasting almost until the end of the year, in which the burning of hayricks was an iconic feature. [what does iconic mean in that sentence?] The unrest led to 19 hangings, more than six hundred gaol terms and five hundred sentences of transportation. The use of arson as a weapon of protest, symbolic of revenge, destruction and cleansing, had been psychotically perfected by Jonathan Martin. [i.e. when he set York Minster on fire. Arson, apparently, is a crime than can be perfected, psychotically.] Its deliberate employment to terrorize the government  during the Swing uprising seemed now to fulfil Mary Wollstonecraft's dire prediction of the potential evils of the Promethean myth." [I think he is talking about Frankenstein's monster in the book by Mary Shelley]. 


Then "The opening of 15 September 1830 of the Liverpool and Manchester Railway was an event almost impossibly overloaded with symbolism." 



This grand opening was marred by the awful accident of Huskisson being knocked down by the Rocket, his leg severed, and dying of the injuries. What does Huskisson symbolise in that scene? The Rocket might symbolise the future power of the common man (having the freedom to travel further) and Huskisson a privileged and landed Tory, but that is rather complicated because Huskisson was on the more progressive wing of the Tory party and was in favour of Free Trade - which theoretically made food cheaper. The political power of his class wasn't knocked down by democratic forces until the next century.


Isn't this a peculiar way of writing history? It sounds as though Wellington might have remarked to George Stephenson, "I say, my man, there's too much symbolism in the air today!" and Stephenson might have said, "Aye, right enough bonnie lad. There's that mooch meaning in ut steam engine as ud turn us all into representations of oor classes."


There were amazing changes going on at that time, in science, art and politics, however, by lumping a load of different men of talent together and labelling them Promethean merely makes the story more dramatic.


"The perfection of his usefulness" - how beautiful
However, the science is well-explained by Max Adams, I think.

Brunel's Tunnel, Rotherhithe to Wapping

The Thames at London was extremely congested. Up until the beginning of the nineteenth century, merchant ships coming into London could only be unloaded between the Tower of London and London Bridge. Sometimes ships were moored for three months on the river waiting for their cargoes to be unloaded. They were easy prey for gangs who cut them adrift and looted them when they ran aground.

Enclosed docks were needed. The first was opened in 1802 by the West India merchants at the northern end of the Isle of Dogs. Other enclosed docks soon followed: the London Docks at Wapping, the East India Docks at Blackwall and the Surrey Docks, all built in the first years of the nineteenth century.

But the nearest river crossing was London Bridge, by now very old and a few miles away from the new docks. An estimated 4,000 vehicles crossed the bridge every day, and 350 Thames watermen also took passengers across the river. Building a bridge this far to the East presented problems - the height of ships' masts meant that the bridge would have had to be very high and the approach roads very long.

The alternative was a tunnel, but the ground under the Thames was soft - gravel, sand and mud. It would not support a tunnel, especially with the weight of the water above. Robert Vazie first tried to build a tunnel in 1807, and the work was carried on by Richard Trevithick, a very capable engineer from Cornish tin mines, but it was flooded just less that 200 foot short of completion. Trevithick proposed a new method: putting cast iron sections into the tunnel excavated from above. This would have worked but it did not attract financial support. The tunnel was abandoned.

A new method was proposed by Brunel pere. His name was Marc Brunel, originally a French naval officer, he came to England to escape the French Revolution.  He went to America where he built a very impressive canal linking the Hudson River with Lake Champlain, so linking New York with the St. Lawrence River.

But in 1818 Marc Brunel patented a device for "forming drifts and tunnels underground". His inspiration was the shipworm, Teredo navalis, which bores into ships' timbers. Digging with the shell-like protrusions on either side of its head, the shipworm excretes the excavated wood out of its body, using it to line and reinforce the tunnel as it moves along.

 
 
 
They started with a shaft at the Rotherhithe end. Marc's new method was to build a brick tower and then simply allow it to sink into the soft riverbank through the downward force of its own weight. At first it appeared to be a tower - an inner and an outer surface of bricks a yard apart, the cavity between them filled with cement and rubble. A superstructure was then set on top of the tower on which a steam engine was assembled to pump away the water which the shaft encountered as it sank and to bring up buckets of earth from the bottom.

The structure weighed nearly 1,000 tons and sank into the ground at a rate of a few inches per day. The downwards progress of the shaft at Rotherhithe became one of the most popular and fashionable sights of London. After it was fully sunk diggers had to go down and give it a foundation and leave an opening for the tunnelling shield, and also dig a reservoir for water drained from the tunnel workings. Marc designed his own steam engine, installed above the shaft to drive the tunnel pumps and bring up the earth in buckets.
 
The shield was an iron frame facing the direction of the tunnel, rectangular. The miners worked in independent cells digging out a small patch at a time, while the frame was braced against the bricks the bricklayers had just finished laying, 6 deep lining the tunnel. Below you can see the miners working in the frame on the right and spoil being removed and bricks brought.









Finally the great shield was lowered into place 63 feet below the ground and the boring of the tunnel began. When fully manned, thirty six miners excavated a tunnel face of approx. 800 square foot. There were two eight hour shifts.

Marc had been taken ill even before the tunnelling got under way, and in 1826 the resident engineer also became ill and resigned. Isambard, Marc's son, had been involved in the work from the beginning. He often stayed below ground supervising the progress of the great shields for up to 36 hours at a time. In January 1827 his appointment as resident engineer was made official. He was only twenty years old.

Isambard was given three assistants, but all were prey to diseases because the river bed was composed of toxic substances, methane gas and foul water. One of the assistants died almost immediately. Workmen and overseers also fell ill. In February 1827, with 300 feet of the archway completed, the directors of the tunnel decided to allow the public to visit the work. Marc protested as the earth was inconsistent and gravel layers threatened the works with flooding. At the end of April up to 700 visitors were coming each day, for the charge of one shilling. The directors cut the workmen's wages which resulted in a strike.

Then there was a flood...
Marc had a stroke...
Another flood...
The tunnel was bricked up...

Today you can see the tunnel at Wapping station on the East London Railway, part of the Overground. You can't see any more of it because it is in use by trains. It is an International Landmark Site, one of only four in the country (and only 250 in the world). Here the Brunels pioneered a method of tunnelling used in every tube system all over the world ever since.





The museum at Rotherhithe tells all the story and you can go into the shaft, but they haven't much money with which to buy exhibits and they need funds to buy items like Brunel's drawings. Please visit and buy books and souvenirs.
