Uccello and the Problem of Space

Posted in Art, Television, The Universe and Stuff with tags , , , , on August 12, 2016 by telescoper

The other night I was watching an old episode of the detective series Lewis and it reminded me of something I wanted to blog about but never found the time. The episode in question, The Point of Vanishing, involves a discussion of a painting which can be found in the Ashmolean Museum in Oxford:

Uccello_TheHunt

I won’t spoil the plot by explaining its role in the TV programme, but this work – called “The Hunt in the Forest” or “The Night Hunt” or some other variation on that title –  is by one of the leading figures of the Early Renaissance, Paolo Uccello, who was born in Florence and lived from about 1396 until 1475. He was most notable for his explorations of the use of perspective in painting, and specifically in “The Problem of Space”, i.e. how to convey the presence of three dimensions when the paint is confined to only two. This picture accomplishes this not only by having a clear vanishing point in the centre of the composition, but also by the arrangement of the figures. Notice how the figures in the foreground are generally moving in the plane of the canvas, but towards the centre they are heading away from the observer. The composition thus acts like a funnel, drawing the viewer’s eye into the centre of the picture and then off into the distance, and the darkness.

Two other things are of interest here. One is that it’s not at all clear what is being hunted, or even whether there’s anything out there in the darkness at all. Is the hunt a metaphor for something else, perhaps the pursuit of something unattainable?

It’s also clear that Uccello wasn’t as interested in realism as he was in geometry and proportion. The horses, dogs and people are drawn in a rather primitive style reminiscent of mediaeval painting.  I think that suggests a metaphorical interpretation of the subject matter.

I see this painting as  a brilliant experiment in geometry rather than an attempt to depict a likeness of an actual event.  Reading about Uccello reveals him to have been somewhat obsessive about perspective – his  friend, the great artist Donatello, remarked that Uccello  spent too much time studying and not enough painting – but his contribution to the development of painting techniques during the Renaissance period was immense.

Although Uccello may have taken it to an extreme, interest in the formal, geometric, aspects of art wasn’t at all unusual in this period. I blogged a while ago about another favourite Renaissance artist, Piero della Francesca (c. 1415-1492) whose life overlapped with Uccello. He combined his work as an artist with a distinguished career as a Mathematician. It would be surprising if Uccello and Piero della Francesca never met, but a quick search didn’t find any definitive evidence that they did.

Another great example of Uccello’s art is this:

g013_uccello_rout

It is one of the three panels of The Battle of San Romano. Again, the living figures are simply drawn – the bodies, weapons and bits of armour on the ground look like they might be toys on a nursery floor – but the way the painting gives the impression that everything is receding into the distance is remarkably effective.

But the best example of Uccello’s work that I’ve seen in the flesh (so to speak) is this:

Paolo_Uccello_Deluge_web

This – Flood and Waters Subsiding –  is a fresco located in the Church of Santa Maria Novella in Florence. Unfortunately it’s quite badly damaged – not only have the colours faded badly but parts of the plaster have crumbled away entirely. Fresco is a notorious fragile medium and it’s sad that so many great Renaissance works of this type have been lost over the years. However, despite the disrepair, this is still an amazing piece. Perhaps helped by the semi-circular space into which it was designed to fit, this work manages to convey a sense of vorticity; There’s not so  much a vanishing point as a point of origin and the action seems to swirl around it as well as to emerge from it. Note also that in contrast to the previous two paintings, the figures in this one are very lifelike, although the fading of the colours gives them a rather ghostly appearance. It’s also interesting that this work pre-dates The Hunt in the Forest by at least twenty years so the movement away from realism was something that happened in later life.

I’ve often wondered why I feel so intrigued by Early Renaissance Art. Of course these works are beautiful or exciting or in some other way pleasurable to look at, but there’s much more to it than that. They inspire curiosity. What is going on? Who are these figures? What is being hunted? Why is everything arranged in that particular way? And the act of looking at a painting like that , and being curious, perhaps reminds us that curiosity is so important for its own sake.

 

Flaming June Again

Posted in Art, Biographical, Bute Park, History with tags , , , , on June 10, 2016 by telescoper

Since we’re in the middle of a modest heatwave I thought “Flaming June” would be a good title for a blog post. Until a few years ago I always thought that “Flaming June” was some sort of folk expression or quotation from a poem, but it is instead the title of this Pre-Raphaelite painting by Frederic Leighton of a lady wearing what looks like a dress made out of old curtains. Apparently the oleander branch seen in the upper right symbolizes the fragile link between sleep and death. It looks to me like she must be attending a lecture…

But I’m rambling. This has been an exhausting week, probably because I a few days off last week and have come back to one of the busiest periods of the academic year. The examination period is over so there are scripts to mark,  examiners’ meetings, class lists and the like, all parts of the arcane business of academic life. In fact I’ll be spending the first three days of next week in Cambridge where I’m External Examiner for Physics, and I have a lot to do here before I go.

In between all the meetings I had to attend yesterday I noticed that it was the 9th of June, a date of enormous cultural significance for those of us born on Tyneside, as Geordie Ridley’s famous music hall song The Blaydon Races begins “I went to Blaydon Races, ’twas on the 9th of June… The original Blaydon Races were horse races and site of the course is long since gone, but the name has recently been resurrected as a road race involving people on foot rather than on horseback. Incidentally, the usual “Whit Week” holiday in late May or early June is still referred to on Tyneside as “Race Week”.

All this reminded me of the occasion – over twenty years ago – when I entered the Great North Run for the first time. Nowadays this race – the biggest mass participation half-marathon race in the world, with 50,000 competitors – is run in September, but in those days it was held in June. As it happened, there was also a heatwave the first time I did it. I remember lining up at 9.30 on a Sunday morning on the start grid (I was number eleven thousand and something) while the stewards went round pleading with all the participants to take plenty of water as they went around as it was going to be very hot indeed and they didn’t want people suffering from dehydration.

In those days I was quite a keen long-distance runner and was fairly fit. I wasn’t that concerned about the heat but took the advice to heart and determined to stop at all the water stations on the way from Newcastle to South Shields. When we started I also took care not to go off too fast over the first mile or so, which is basically all downhill from the Town Moor to the Tyne Bridge. Not that you could go fast anyway, as the track was so crowded with runners.

I remember the wonderful feeling as we emerged onto the Tyne Bridge and took in the splendid view of the bridges along the river. When we got to Gateshead the crowds were out in large numbers cheering everyone on and I felt completely elated. The first water station was near Gateshead athletics stadium, and I took a drink there as I did at the next, and the next. After Gateshead the route heads towards the Felling bypass at about 4-5 miles and then the runners can see a long climb in front of them. A large thermometer showed the temperature on the road to be about 45 Celsius. Fortunately the people living in houses either side of the road were out in their front gardens offering encouragement and sometimes had their hoses out to shower people as they went past. At one point there was a fire engine that had made an impromptu fountain by the side of the road too.

Unfortunately, as I near the ten mile mark I started to feel a bit strange. I had never actually taken on water while I was running before this race; I never felt the need for it when on training runs. My stomach wasn’t used to the water sloshing around while I was running. I felt quite sick by the time we got to the top of the climb but when I saw the sea and felt its breath on my face I cheered up and descended the steep downward slope towards the seafront near Marsden Rock.

There’s a good mile and a half along the seafront to the finish, however, and I was definitely struggling really badly by then. I could see the finish line but it felt like it wasn’t getting any closer. I slowed to a crawl but kept going, finally reaching the grandstand where a large crowd shouted encouragement. I must have looked dreadful because I heard several people shouting out my number along with “keep going, son”  and “you’re nearly there”.

Eventually I got to the finish line but the feeder lanes were quite busy then – I was finishing at about the peak  time of about 1hr 50 – so I was forced to slow right down because of the people in front of me.

As I crossed the line, I stopped running and was immediately overcome with nausea. I bent over, hands on my knees and emptied the contents of my stomach – mainly water – all over the grass. I felt absolutely dreadful but, after a quick check from the St John Ambulance crew who were on hand, I recovered and found my folks who were nearby. After we got home and I had a shower I felt fine.

About a week later, when I had returned to my flat in London a letter arrived for me. I opened it up and found a small passport-sized photograph, with the caption “YOUR MOMENT OF TRIUMPH”. It turns out there was an automatic camera near the finishing line that snapped everyone crossing it along with a shot of the digital clock showing their finishing time. The idea is that you could order a blow-up of the picture for £25 to put on your wall.

In my case, though, the picture showed not a moment of splendid athletic achievement, but a bedraggled creature puking uncontrollably while those around him looked on in disgust. I didn’t order the blow-up of my throw-up.

Over the years I did the Great North Run a number of times – six or seven, I don’t remember exactly – and a few marathons too, but the strain of running on the roads around London gradually told on my knees and I had to stop because of recurrent pain and swelling. Eventually, a few years ago I surrendered to the inevitable and had arthroscopic surgery to sort out the damage to my knee joints. That seems to have fixed the problem, but my running days are over.

 

Mystery Photograph

In lieu of a blog post today, I thought I’d post an intruiging photograph. See if you can figure out what this shows:

This is not a spiral

Posted in Art on April 11, 2016 by telescoper

Talking of art, feast your eyes on this image from a really interesting website called CosmusUp:

Spiral

Picture courtesy of CosmosUp

It’s a stunningly convincing optical illlusion. You can see how it works if you draw an horizontal line through the centre. The small black and white squares at the corners of the larger ones are aligned differently on the inside and outside of each ring and alternate in orientation as you go around. This creates a pattern of black squares that appears to bend, creating the impression of an anti-clockwise spiral.

Constructed Universe

I saw this interesting piece “Constructed Universe” (1983) by Daniel Faust from the Metropolitan Museum of Art  via Twitter and it intrigued me enough to share it here, although some of you might think it’s just a load of balls.

The last time I posted a work of astronomically-themed art by Wassily Kandinsky it proved unexpectedly  popular so here’s another one, called Comets. This is also a lithograph and also dates from around 1938.

Jazz, STEM and the Creative Process

Posted in Art, Jazz, The Universe and Stuff with tags , , , , , , on January 23, 2016 by telescoper

The Times Higher has given me yet  another reason to be disgruntled this week, in the form of an article that talks about the possible effect of the proposed Teaching Excellence Framework (TEF) on “creative” subjects. What bothers me about this piece is not that it criticises the TEF – I think that’s an unworkable idea that will cause untold damage to the University system if, as seems likely, it is railroaded through for political reasons – but that the author (Nigel Carrington, Vice-Chancellor of the University of Arts London), like so many others, lazily implies that STEM disciplines are not creative. I think some of the most intensively creative people in the world are to be found in science and engineering and creativity is something we try very hard to nurture in students at Sussex University regardless of discipline.

Anyway, while feeling grumpy about this article, I remembered this video of an interview with the great jazz pianist, Bill Evans. Jazz is undoubtedly an intensely creative form, not only because it requires spontaneous real-time conversion of ideas into sounds. Evans talks with great passion and insight about creativity in music-making, but the striking thing about what he says at the  very beginning about the need to analyse your subject at a very elementary level before proceeding in order to create something that’s “real” applies equally well to, e.g. theoretical physics as it does to jazz.

In the following section he reiterates this point, but also stresses the discipline imposed by a particular form and why this does not limit creativity but makes it stronger.

It’s better to do something simple that is real. It’s something you can build on. because you know what you’re doing. Whereas, if you try to approximate something very advanced and don’t know what you’re doing, you can’t build on it.

No matter how far I might diverge or find freedom in this format, it only is free insofar that it has reference to the strictness of the original form. That’s what gives it its strength.

In much the same way, theoretical physics is not made less creative because it has to obey the strict rules of mathematics but more so. This is true also in the fine arts: the more limited the canvas the more creative the artist must be, but it also applies to, e.g. engineering design. Self-teaching is important in STEM subjects too: the only really effective way of learning, e.g. physics, is by devoting time to working through ideas in your own mind, not by sitting passively in lectures.

All subjects require technical skill, but there is more to being a great jazz musician than mastery of the instrument just as there’s more to being a research scientist than doing textbook problems. So here’s to creativity wherever it is found, and let’s have a bit more appreciation for the creative aspects of science and engineering!

 

 

 

“Stars” by Kandinsky

Posted in Art with tags , on January 17, 2016 by telescoper

No time for a proper post so I thought I’d fill a bit of space with Stars, or at least with a picture of the lithograph of that title by Wassily Kandinsky made, I think, in 1938. It is certainly a different kind of image from that produced by astronomers, but it does put me in mind of star-forming regions such as the Orion Nebula..

Variations on the Theme of Northern Lights

Posted in Art, The Universe and Stuff with tags , , , , on December 9, 2015 by telescoper

This morning I woke up as usual to BBC Radio 3. Unusually however this morning’s breakfast programme was broadcast live from the picturesque town of Tromsø in Norway, which is well inside the Actic Circle so is dark all day at this time of year. The broadcast from Norway part of a three-week extravaganza called Northern Lights, which focusses on the music and culture North of 60° latitude.

Anyway, this prompted me to do a brief post about a couple of related matters connected by the theme of Northern Lights.

The first is to draw your attention to the fact that, to coincide with this Nobel Prize Week in Stockholm, the artist Olafur Eliasson has set up a temporary public artwork in Stockholm called Your Star, which involves putting an artificial star into the sky over Stockholm. I gather it has been quite difficult to get the star to behave in the windy conditions, but in any case you can use the website to view six short videos and even create your own star..

The second is this wonderful video of the  Aurora Borealis? If you haven’t seen this before then take a look. It’s not a fake. This is what it’s really like.

I stood under a show like this once, in Tromsø in fact, and I can tell you ever the word “awesome” applied to anything, this is it. The curious thing is that I had the definite feeling that there was a booming and whooshing sound to go with the light show. I wasn’t the only one there who thought they could hear it as well as see it. And I wasn’t drunk either. Well, not very.

I’m reliably informed however that there is no physical mechanism that could produce sound waves of sufficient power to reach ground level from the altitude at which the light is generated. It must have been psychological, as if the brain wants to add a backing track when it sees something as spectacular as this. Any views on this phenomenon would be welcome via the comments box..

 

UPDATE: here’s an interesting take on the Auroral Sounds issue.

Little Sun Charge by Olafur Eliasson

Posted in Art with tags , , on September 29, 2015 by telescoper

You might remember a piece I did a while ago about Little Sun by the artist Olafur Eliasson. This is a solar-powered lamp that charges up during the day and provides night-time illumination for those, e.g. in sub-Saharan Africa, without access to an electricity grid. I supported this project myself, including writing a piece here as part of the Little Charter for Light and Energy.

Well, it seems that in his travels around the world promoting Little Sun, Olafur received a lot of comments about how great it would be if the same principle could be used to provide a solar-powered mobile phone charger. So now – lo and behold! – there is a new product called Little Sun Charge. Here’s a little video about it:

I’m mentioning this here because Olafur is attempting to crowdfund this project via a kickstarter campaign. The campaign has already exceeded its initial target, but there are five days still remaining and every penny raised will used to reduce the price of the charger so that it can be sold to off-grid customers for even less than originally planned.

So please visit the link and pledge some dosh! There are treats in store for those who do!
