Siddington canal bridge
Cirencester and its surroundings have changed dramatically over the years. This old bridge in Siddington takes a country lane over the old Thames and Severn canal. Although the canal is derelict, looking down from the bridge you get a clear view of the ladder of locks that used to be here. The good news is that the canal is being restored and is already in water again through Stroud. It will be reconnected to the national canal network within the next three years or so. Work has also started at the Cotswold water park, repairing the section from the spine road to Latton, and in Lechlade where it joins the Thames.
Sadly, there is no plan to restore any part of the Cirencester Arm of the canal, but it’s possible to trace the route of the towpath almost the entire way from Siddington to the bottom of Querns Hill where Cirencester Wharf used to see the loading and unloading of cargo.

The gap has been closing little by little from both the astronomical and biological sides. But though it’s narrower now than ever before, it’s still a gap.
How did life begin? It seems possible, even very likely, that simple chemistry has the potential to generate life given the right conditions and plenty of time.
There’s always been a big puzzle over the origin of life here on Earth. Life is everywhere and in a vast array of forms. From the simplest archaea and bacteria, to the giant redwood and the humble grass in the field, the blue whale down to the smallest mite. So rich in variety, so wide in its presence from the deepest oceans to the highest mountains. Life is amazing!
The processes of evolution are well understood and impossible to deny; so puzzles over the many forms of life, its adaptability, and changes in the forms we see coming and going over deep time are clearly understood and well explained by biologists. (When did you last see a dinosaur?)
But how did it all start?
Ah! That has always been the unexplained mystery. Once we have a simple, replicating form of life on the planet we can see it might thrive, spread and grow in complexity.
There are various proposals. Perhaps it arrived in an asteroid kicked off Mars or somewhere else. But that does no more than move the origin to a different place in the Solar System. Maybe it all began at mid-ocean ridges where hot mineral-laden springs flow from hot rock layers below the surface. Perhaps, yes.
We know that many of the precursors for life exist out among the stars. Here in the Solar System, comets and asteroids are often richly endowed with amino acids, ribonucleotides, and all sorts of smaller precursors. These are the building blocks of proteins, RNA, DNA and so forth. We understand how these precursors can form spontaneously given simpler materials like water, methane, ammonia, compounds including atoms of phosphorus, sulphur and so forth. It just takes chance interactions, time, and a source of energy like ultraviolet light. The basic ingredients are there in the gas clouds that condense to form new stars and the material orbiting in disks around them.
All of these things are fairly well understood, but there’s a gap in our understanding between the presence of the components and the presence of life. The gap has been closing little by little from both the astronomical and biological sides. But though it’s narrower now than ever before, it’s still a gap.
Life in a computer?
Well, yes! And, no.
Some clever work by Blaise Agüera y Arcas, a Google vice-president of engineering, has uncovered an intriguing process. Setting a very simple ‘machine’ running random code (no meaningful program whatsoever) and waiting for something to happen, shows that eventually some very simple self-replicating code will appear in the system, and once it exists it replicates very quickly and then slowly increases in complexity. It’s not biological life of course, but it has all the qualities that we would recognise as lifelike. It replicates itself, different forms of replicating code compete with one another, they evolve, and they grow more and more complex. This doesn’t show us in any detail how biological forms got started, but it demonstrates that self-replication could happen in principle, and given enough time that it’s almost inevitable.
For the detail and background you should listen to Sean Carroll interviewing Blaise, the conversation is absolutely fascinating.

Yellow flag Iris
These beautiful, water tolerant, native Irises pop up every year in the waterways in and around Cirencester. The photo was taken at the junction of Riverside Walk and Gloucester Street right by Abbey Way Services. The photo was taken in May, just as they were reaching their best.
Although our natural environment is struggling to cope with the many pressures we put on it, some species manage to do quite well. This is one of them. But there are many others that are in danger. Some of these, plants and animals, are fairly stable or even recovering in and around the Cirencester area with careful conservation management. Examples include the lovely snakeshead fritillaries that flower abundantly in North Meadow just south of Cricklade, pasqueflowers in a strong colony to the north of the town near the Stow Road, and the large blue butterfly on a reserve west of the town and on common land near Stroud.
NOTE: If you visit any of these sites, please treat them with respect. Stay on marked paths if they’re available, avoid trampling on plants, stay out of restricted areas, and definitely don’t dig anything up. Pay attention to signs and notices. Thanks!
Other species, once rare but now much more common include red kites, you’ll see these frequently in the skies around Cirencester, often flying very low, even over housing estates. Back along Riverside Walk you may be lucky enough to see a heron, a kingfisher, or a little egret.

After finishing her education and working in management roles at a number of major companies in Pakistan, Sabeeta still had the continual feeling of background obstacles and pressures because of her faith.
Here, in brief, is the story of Sabeeta, beginning in Pakistan as a child with an awareness that she and her family were not entirely acceptable and eventually moving to the UK with her husband.
From Qayyumabad
Pakistan to UK
Sabeeta Mushtaq writes about her life in Pakistan where she lived in constant awareness that as a Christian in a Muslim culture, she was seen as a misfit in her country of birth. It’s difficult for many of us here in the UK to imagine what this must be like. Though regrettably, some people living in Britain with non-UK backgrounds might feel related tensions and anxieties.
After finishing her education and working in management roles at a number of major companies in Pakistan, Sabeeta still had the continual feeling of background obstacles and pressures because of her faith. Later still she married a British citizen and after a few more years they made the decision to move to the UK…
To London
…arriving in the difficult early days of COVID.
Eventually she found friends and a spiritual home in a London Anglican congregation and has now become a Lay Deacon. I like her closing sentence and quote it here in full:
My journey, though filled with obstacles, has strengthened my belief that God’s plan for us unfolds in ways we cannot always foresee, but in the end, it is always for a greater purpose.
All of us are on our own, individual journeys, with or without Jesus. And in my opinion, far better with than without! Read Sabeeta’s full story at Anglicanism.org.

Christmas lights
This is Cirencester Market Place on 5th January 2021, still in its decorated-for-Christmas state. In the 17th century this space was full of buildings and narrow streets. Roughly where the red car stands, imagine an old inn with a street either side, and beyond it two rows of buildings, Butter Row and Butcher’s Row, so three streets at that point. Many old buildings were destroyed in town improvement schemes over the years. If they still existed today they would attract preservation orders.
If you could visit the Market Place in 1500 you would struggle to recognise anything other than the Parish Church. All the fine, Cotswold stone buildings were constructed more recently than that, the shops and dwellings at that time would have been timber framed with overhanging upstairs floors. The entire look and feel of the place would be different. At that time the Abbey was thriving with the Abbey Church behind the existing Parish Church. The entirety of what is now the Abbey Grounds would have been busy with monks on errands and at work in the gardens, at the fishing lake (still there today), in the mill and bakery and so much more. It was almost a walled town within a town.
In the year 1000, shortly before the Norman invasion, some of Saxon Cirencester may still have been outside the old Roman walls, but there was a Saxon church in the area of the Abbey Grounds and it’s likely that other parts of the Roman City would have been cleared and put to use.
And in the year 500 the Romans had left only 100 years earlier. The city would have been more or less intact, but derelict. Initially, Saxon settlers lived outside the old city walls. Some of those walls would still have been standing, at least in places, and the larger buildings inside the city would have been identifiable – the Basilica, the Forum, and probably Baths and a Theatre (now lost). The Saxons built timber framed houses and farms initially outside the walls. Piles of rubble and stone, no doubt ridden with extensive and impenetrable growths of brambles and trees, would have seemed far less useful than the arable land outside the old walls.
Go back another five hundred years and the area where the town now stands consisted of a flood plain with low gravel banks and the River Churn meandering through. There would have been yellow iris, water mint, alder and willow in wetter areas with other trees on higher ground. The waterways would have been easily forded and the local Dobunni people likely fished in the area and farmed on higher ground nearby. The Roman army constructed the Fosse Way from Exeter to Lincoln and built a timber fort in the eastern part of modern Cirencester. It’s likely that a trading settlement grew up near the fort and the town was officially recognised in 75 CE. By the later Roman period it had become the second largest city in Britain (London was the largest).
All of this took place in and around the area we know today as Cirencester Market Place.
