Hands-free trekking umbrella

What the…?

This post is my solution to using an umbrella hands-free. Sometimes when hiking, or walking with trekking poles, it can be useful to use an umbrella. Now, before I get shouted down by the ultra-lightweight hikers, it is, of course, a personal choice. The problem with an umbrella –aside from weight – is that it requires a means of support, usually a hand, but this is incompatible with using trekking poles, or indeed dealing with using a camera, a phone, or just about anything else.

Why use a trekking umbrella?

So why use one at all? Walking the Camino in 2016, I found I was walking sometimes in warm weather, sometimes in rain. In terms of heat, I was walking West in the mornings, and hence the sun was almost always at my back. Despite a hat, and the shade of the backpack, I found I was getting a sunburnt neck, and there were times when it would just have been nice to have a shady tree to walk under. There are not many of those on the rolling plains of the Meseta in Spain, so some form of shade is a good idea. It was too hot for a hood, and it was nice just to be able to take advantage of whatever light breeze might be available.

I did carry a lightweight umbrella last time, but had no way of attaching it to my pack, so it was always a choice between using the poles or using the umbrella – so it got very little use.

As I prepare for my next Camino, I thought I’d sort this issue – and researched hands-free umbrellas for trekking. I wound up buying the ‘Dainty’ model of the Euroschirm trekking umbrella [this is not an affiliate link, and my opinions are my honest response] – it was the lightest one (195g/7oz) that folded down to the smallest package. And it was reflective silver, and UV treated so it can be used equally as a sunshade or against the rain.

Alas, it didn’t have any mounting system, so it was time to devise my own.

How to attach it

My backpack has two loops on each of the front straps – designed to run the hydration tube down either side. The umbrella did not have a loop of any kind, so I drilled a small hole in the plastic handle to take a keyring ring from a $2 shop and threaded the keyring loop through so it was permanently on the umbrella. I then bought a set of four velcro cable ties – called ‘One-wrap’ from Officeworks – $7.30 (NOTE: this is also not an affiliate link – just there to show what I used). The reason I chose these is that they can thread back through themselves, so I could attach it to the backpack loops making them always available for attaching the umbrella. The free end of the velcro is then wound around the umbrella and attached to itself. When you undo it, the velcro remains on the pack and the umbrella can be easily put away for another time.

I threaded one velcro loop on one pack loop and another on the other pack loop on the shoulder strap. I then used these to secure the keyring ring to the lower one and the upper one around the shaft of the umbrella. This gives a secure hands-free mount which can be used on either strap depending on which side the sun is shining. It works like this:

This system will work with any manual or automatic umbrella and does not require any specialist fasteners (or a specialised umbrella).

Conclusion

The result is I can have my own personal shady tree equivalent regardless of the presence of any shade. And the umbrella has the added bonus of keeping the rain off the top of the backpack too, so is suitable for light rain. Does it work? I took a daypack with me sketching on a clear mid-summer day in Australia with a temperature approaching 40C/104F and deliberately sat out in the full sun while I sketched for an hour and a half. The umbrella performed brilliantly and kept me cool enough to focus on my sketching, rather than on the way the bitumen was melting. With the UV protection and the silver reflective covering, it was like sitting under a shady tree. It felt several degrees cooler than the ambient temperature. From this test, I have decided the umbrella is well worth its 190g/7oz weight and will be coming with me on my next Camino.

Just a small aspect of my Camino preparations for our 2018 walk across Spain.

Cassini – Science the Church and a Gnomon

As the Cassini Saturn probe prepares for its final few orbits before being de-orbited into the planet, it’s worth considering who it was named for – the C16th Italian astronomer Giovanni Cassini. These days the Vatican collaborates with the European Space Agency and NASA on space science. Even the Vatican Library uses an image file storage system developed by NASA – it was a system originally designed for radio astronomy.

 

But it is worth remembering that the Church has often had an uneasy relationship with science. Galileo Galilei was tried in 1633 for heresy by the Inquisition and was sentenced to formal imprisonment – one of the Church’s ‘oops’ moments – later commuted to house arrest.

In 1582, when Galileo was just 18, Pope Gregory revised the calendar, as the Julian calendar developed under Julius Caeser was getting embarrassingly out of step with the solar year (it lacked leap years). But the introduction of the more accurate Gregorian calendar that we use today, presented a new problem. The major Feast Days needed some re-calibration. The most difficult one was Easter – a so-called Moveable Feast – and a pretty important one to the Christian faith. It was supposed to fall on the Sunday following the first full moon after Spring Equinox (20 March). While today we just look it up on Google or wait for Facebook to remind us, it was a bit more complicated back in the C16th. You see, the problem was that the Church followed the lunar year, while everyone else followed the solar year, and they don’t quite match up. It was time to find some astronomers who hadn’t yet been executed for heresy, and who would admit to being astronomers… no pressure then.

Genovese astronomer Egnazio Danti (cosmologist to Cosimo de Medici I) was called to Bologne to work with Pope Gregory’s Calendar Commission to help determine accurate dates for the Spring Equinox – and by extension, Easter. He constructed a Gnomon – a sight line – inside the Basilica of San Petronio in Bologne and cut a hole high in the wall to allow the sun to shine through onto the gnomon. This was used to determine the path of the sun at certain times of the year, and help with measuring the lunar cycle too. But less than 100 years later, some renovations designed to expand the Basilica meant that the wall with the hole for the sun was removed (oops)… So in 1655, a mere 20 years after Galileo’s death, Giovanni Cassini was brought in to design a new gnomon in the same church. His ambitious plan was to build a much longer gnomon for more accurate observations. His ulterior motive was to prove Galileo’s observation that the Earth went around the sun, not the sun around the earth – this time without getting into trouble with the Inquisition.

So what has this to do with travel? You can still see Cassini’s gnomon today in the Basilica of San Petronio in Bologne. But if you are visiting Rome you can find another Gnomon – it’s worth checking out the floors in some of these churches, and look for an angled line in bronze running across the floor… There’s also one at the Church of San Sulpice in Paris (pictured below) – made famous by the movie of Dan Brown’s ‘The Da Vinci Code’.

Church of St Sulpice Paris

The C16th Basilica of Santa Maria Degli Angeli in Rome was dedicated as a Basilica in 1920 by Pope Benedict XV in 1920. But from the outside, it doesn’t look much like a church at all. Curiously, it was built inside the ruined Frigidarium of the Roman baths of Diocletian (ca 300AD), thus preserving a significant part of the ancient Roman building into the modern age.

The church itself was designed by none other than Michelangelo. So, from a simple ancient Roman exterior, you enter into a magnificent Renaissance church of breathtaking scale – one of the world’s largest.

But I had heard that it held one more surprise. A gnomon. The gnomon here was copied from Cassini’s design. Pope Clement XI commissioned the astronomer Francesco Bianchini to construct the Gnomon. Bianchini was Secretary of the Calendar Commission, and h chose the Basilica of Santa Maria degli Angeli because of the stability of its Roman walls and foundations, and because of its height and large internal space. Bianchini improved on Cassini’s design by allowing for the observation of stellar transits – even in daytime.

Here you can clearly see the sun approaching the meridian line.

The pinhole occulus through which the sun shines is located high on the wall, and to give it a clear path, part of the entablature and the capital of the pilaster – designed by Michelangelo – was cut away – perhaps a metaphor for the tension between art and science and the church! I have added an arrow to show where the sun enters.

The church also houses a Foucault pendulum which demonstrates the earth’s rotation through the pendulum’s elliptical swing.It was invented by French scientist Leon Foucault, who first demonstrated it in 1851 at the Paris Observatory – it now resides in the Museé des Arts et Metiers in Paris.

The pendulum weight is in the form of a globe as though pushed with a giant hand. Metaphors for force were quite literal! As you can see below

So, from a C16th astronomer seeking to solve the Church’s problem with Easter through detailed observations of the Sun, to a spacecraft providing detailed observations of Saturn we can glean nearly five centuries of the Church’s relationship to science and the arts by visiting a two-thousand year old Roman bath house renovated by Michelangelo in Rome. And all this, from noticing a strange geometric pattern on the floor of a church! It does pay to look down sometimes!

Paris – the final pack for the Camino

Arriving back in Paris after a two-day visit to Northern France to see some friends, it is time to get serious for the final pack. We will be sending a bag on to Santiago de Compostela with our smart clothes, so we will only have the bare essentials for the backpacks we’ll take on the Camino de Santiago (French route).

Camino pack

We repacked several times, weighing the packs each time, only to find them still too heavy, so we repacked again.

See here for my packing video made before we departed from Australia.

With the third re-pack it is uncomfortably apparent that my DSLR camera is just too heavy – it weighs almost 1.5kg in its bag. So it’s hard decision time. Reluctantly, I have to admit that my 10kg backpack is right on the limit – and that is without water – or the camera! So, with the decision made, I packed the camera in the send-on bag and resolved to work on my iPhone camera skills.

With that decision made, and the packs as light as we could manage, it was time to get some sleep – to be ready for an early check-out and a short walk to the Montparnasse railway station.
