Pornte Vecchio: A portrait of old urbanism.

Over at my Ape Man blog, I have discussed New Urbanism on occasion (largely because I read Architecture + Morality and I sometimes desire to contribute to the discussion). I am generally sympathetic to the aesthetics of New Urbanism, but I doubt current American values will ever enable it to work.

I am not happy about that. If cities conformed more to the ideals that inform New Urbanism, I might not mind visiting them as much as I do now. I say that not because there is any currently built example of New Urbanism that really impresses me. Rather, I have sympathy with New Urbanism because there are many examples of Old Urbanism that I admire.

One such example of Old Urbanism that I admire would be Ponte Vecchio bridge in Florence.

Picture of the Pornte Vecchio Bridge

The picture above really isn’t big enough for you to really appreciate it. So I recommend that you go to G|o®g|O’s Flickr page and look at the picture in its original size.

One of the first things that you will notice about the bridge is that it has houses built on it (actually they are shops, but we will get to that in a bit). The second thing you will notice is that there is a causeway that runs across the top of the bridge. If you are observant, you will also pick up on the fact that bridge is old. Very old in fact.

According to Wikipedia,

Believed to have been first built in Roman times,[2] it was originally made of wood. After being destroyed by a flood in 1333[2] (save two of its central piers, as noted by Giovanni Villani)[3] it was rebuilt in 1345,[4] this time in stone. Most of the design is attributed to Taddeo Gaddi.[5] The bridge consists of three segmental arches, the main arch has a span of 30 meters (98 feet) the two side arches each span 27 meters (88 feet). The rise of the arches is between 3.5 and 4.4 meters (11½ to 14½ feet), and the span-to-rise ratio 5:1.[6]

It has always hosted shops and merchants (legend says this was originally due to a tax exemption), which displayed their goods on tables after authorization of the Bargello (a sort of a lord mayor, a magistrate and a police authority).

Although the Wikipedia article would lead you to believe that people set up shops on the bridge for tax reasons, I strongly suspect that there were more practical reasons. The earliest shopkeepers on the bridge seem to have been primarily butchers up until the time the Cosimo I de’ Medici drove them off. I suspect that butchers found it handy to be able to throw their waste products in the water. The government of Florence may have originally felt that this was desirable from the standpoint of public health and hence the tax breaks.

Regardless of the reasons for why it was built the way it was built, I find it impressive that a structure in heavy use has lasted so long. To me, this is the ultimate testimony to a good design.

Close up of bridge

In the picture above, you can see some of the design details a little better. Although, again, I would recommend that you go to mandydale’s flicker site and see the picture in its original size.

I wonder if those square holes that you see at the bridge were put there to accommodate the original scaffolding. I also wonder if the wood supports for the shops are original or if they have been replaced over the years. If they are original it is pretty impressive. I wonder what type of wood they could have used that would last so long in the moist environment above a river?

One thing that surprises me is the state of disrepair that some of the shops are in. You can’t see the disrepair so well in the picture above (although if you look at the original it is a little more obvious). But take a look at the one below….

Details of the bridge

You would think that a famous tourist site would be kept up a little better. Though I grant you that it would be a trick to repair the plaster on a shop hanging off the side of a bridge. Maybe they are waiting for more shops to get to the same state so they can do a bunch of them at once?

Again, if you want to see a better picture go to kandyjaxx’s Flickr page and look at the original.

On top of bridge

As you can see from the picture above, they certainly keep the front of the shops on the bridge spiffy enough. You can go here to look at a better quality version of the picture above at tbee’s flicker site. The original on tbee’s site is so large that you can really see some of the construction details.

The picture below is also taken from the top of the bridge. Except this time you are looking down the bridge instead of across it.

Again, looking at the original picture at MenuMarco’s Flickr site will give you a better sense of the construction details.

Warning: Your pants may cause abrasion wounds.

When you are working there are all kinds of hazards. Some of them are obvious. You don’t want to fall off a roof. You don’t want to get shocked by electricity. You don’t want to shoot a nail into your foot.

But some of the hazards posed by a hard day’s work are not so obvious. A good example of these not so obvious hazards would be abrasion wounds that your pants can give you. Obviously, such wounds are not a threat to your life. But they can be surprisingly painful and they take forever to heal.

This subject is on my mind because I gave myself one of these wounds a few weeks back and it still is not done healing. Like most injuries, I got it because I was stupid and was not thinking about what I was doing.

It was a long day’s work. I did not even stop for lunch (I subsisted on candy bars and orange juice). I was working in either freezing rain or snow depending on the time of day. But the only concession I made to the weather was a hat and a jacket. This meant that my jeans got soaked.

I did not mind because I was working so hard that I stayed plenty warm. I even managed to work up a sweat in spite of being soaking wet. But as the day went on it became increasing painful to walk, get in a vehicle, or any other action that caused my pants to rub against my inner thigh. Naturally, I ignored this.

As the day turned to night the wind began to pick up. Seeing as I was soaking wet from sweat and the freezing rain this was not a good thing. Eventually my teeth began to chatter and I was faced with the prospect of stopping what I was doing to change into my spare set of clothes or just going home.

I had originally planned on working longer but I knew that once I changed into a spare set of clothes I would no longer feel like working. Sometimes stopping can be deadly to one’s morale. Since I had already worked 16 hours I decided that discretion was the better part of valor and I went home.

Once I got out of the “I am working, don’t bother me” mode, the pain in my leg became more noticeable. When I finally got out of my wet pants and I inspected the damage I was kind of shocked. I figured that rubbed the top layer of skin off or something. I never expected to see the raw flesh with clear liquid oozing from it and the deep black (because it was dried blood) scab that had formed over the widest part of the wound.

The clear oozing liquid was trying to form a scab. Over the coming days and weeks that scab would fall off multiple times and be replaced by a new one. This was painful because every time the scab fell off it would be raw exposed flesh that was sensitive to the slightest bump. Even when the scab was on it was not all peaches and cream because the scab was not as stretchable as healthy skin.

Anything beyond tightly controlled range of movement would stress the scab causing it break up. This is one of the reasons that it kept falling off.

Part of the reason that this wound was as painful as it was is related to fact that the damage is more than skin deep. The first time the deep black scab fell off I was impressed by how deep of a groove my pants had cut into my flesh. Given that it went as deep as it did, I am surprised that bleeding was not more profuse than it was.

I have heard of other people who have had problems similar to this. But most of the time they were wearing coveralls or jeans that were not really suited to work. I thought that because I was wearing a good quality pair of jeans from Duluth Trading Co. that I would be safe. Apparently not.

I think the main problem was that water made my pants heavier. That, combined with the weight of the gear on my belt dragged my pants lower and caused all the damage. Supporting this theory is the fact that it was my left leg that got hit really hard and most of my gear was on my right side. This suggests to me that my pants cocked slightly and caused the abrasion effect.

On the other hand, this happened to my brother once as well. Only he was not carrying the gear that I had on my belt. So maybe I am unfairly blaming my tools. On the other hand, both of us got our injuries while working with wet pants so maybe the weight idea is not completely off.

The obvious moral of this story is to pay attention to your body and don’t always ignore the pain. Plus, always have a dry set of clothes handy. (I did, but I chose not to take advantage of them.)

Its going to be a tough Christmas in the trades

I don’t have much sympathy for the big builders. Especially when they say things likes this….
