Happy April

No April fools jokes here. I’m only fooling around with the usual stuff. I cleaned up my computer. I updated my cycling spreadsheet — I need to ride more. I updated my website spreadsheet — we’re on pace for another record year. I updated some templates that serve the site.

I did some work for classes. This includes writing a lecture that is, really, a shot in the dark. Also I had to watch a documentary that we’re watching in another class. There’s also a lot of grading getting done in my online class. We’ve been reading Jenny Davis’ discussion on affordances, which means we’re about to head into the final project of the semester. It’s a busy time.

And so you make time for all of that by tearing yourself away from the fun stuff, like these guys. How can you turn away from a face as cute as this one?

Her brother, meanwhile, is clowning around in the kitchen. He’s stretching this “I’m on the mail, not on the counter” thing to the limit here. But if he’s being cute and not being a jerk he usually gets a pass.

The kitties are doing great. They are not, however, doing my work for me. We’re going to have a talk about that.

I’m still living in the happy memories of our wonderful Irish vacation. So, I’m sharing extra videos that we didn’t get to at the time. It was a great vacation. I have a lot of footage. This will go on for some time. Enjoy it with me, won’t you?

  

The sheep are everywhere. You can tune them out or enjoy the novelty of it. I won’t be putting a bunch of ovine videos up, but it’s tempting.

New book alert

Phoebe would like to let you know about a book that you should add to your bookcase. Look carefully at the authors.

It’s nice living with an expert. Her consultation fees, however, are rather steep.

It was cute how she played this off. I told her she’d gotten a delivery today. “Oh? Hmmm. What’s in that box? I don’t recall ordering anything. Oh! This came out! And ahead of schedule!”

How do you think I should play it, when I read this book? Should I pretend like I found a typo? Take issue with some key point inside? Say they spelled her name wrong somewhere inside? Carry it door to door? Talk about it in every class next semester? So many choices.

I’m still living in the happy memories of our wonderful Irish vacation. So, I’m sharing extra videos that we didn’t get to at the time. It was a great vacation. I have a lot of footage. This will go on for some time. Enjoy it with me, won’t you?

Downpatrick Head

Our last stop of the day afforded us great views and a fine place to see the sunset. And we only had to go to a place that was so empty that four other people wandered up and it felt crowded and invasive. The italicized text below is copied directly from the signs installed there.

The headland of Downpatrick, or Ceann Dhun Padraig ‘the Headland of Patrick’s Fort,’ from its association with St. Patrick, boasts several distinctive monuments. These include Bronze-Age ring-barrows, early ecclesiastical sites, a promontory fort, and a Second World War ‘Look Out Post.” The most prominent is ‘St. Patrick’s Church’ which now houses a stylised statue of the saint.

Christian gatherings were held here on the last Sunday in July and also on Good Friday. Several unique stone crosses used in these rituals have disappeared, as has a curious stone referenced alternatively as the “Lamb’s Head stone” or the “Anvil Stone.”

Of the growling blow-hols, Poll na Sean Toinne – ‘the Hole of the Old Wave’ is the most impressive and the one most linked to history.

Standing over fifty metres in height and situated eighty metres off Downpatrick Head is the imposing sea-pillar known as Dun Briste – the Broken Fort. The surface of the pillar contains the ruins of an ancient residence which once had a land-bridge forming part of its fortification.

Numerous folk tales tell how the pillar came to be separated from the mainland. Several mention an ancient “ogre-pirate” named either Geodruisc or Deedruisc, who, because of his nefarious activities was left stranded on the rock. In bygone days it was called Dun Geodruisc or Dún Deodruise – ‘Geodruisc’s Or Deodruisc’s Fort.

The Annals of the Four Masters note that in 1393 the land-bridge which joined the pillar and the mainland was washed away during a hurricane. As a result, a number of families were isolated but eventually rescued using “ships ropes.”

I liked this sign, which considers the old place through multiple lenses.

Landscape is not an objective area of land or coastline or bounded space; it is perceived individually through the lens of personal memory and depends on the accepted beliefs through which it is interpreted. On Downpatrick Head there are a number of different landscapes, with the best example being the contrasting landscape of science and landscape of the paranormal, each interpreting differently the identical phenomena which can be seen and experienced there.

The Landscape of Science

The smoothly rising headland of Downpatrick Head is made up of the hundreds of layers of different sediments; sandstones, shales and limestone one over the other and resting undisturbed since they were laid down in a shallow sea, about 300 million years ago. The different rock types are due to the continually changing distance from the coast that the deposits were laid down. The coarse sediment carried out into the sea by rivers was deposited when the coastline was close at hand compacting into sandstone; deposits of finer sediment compacting into shales were deposited when the coastline was more distant while the limestone was deposited when the coastline was so far distant that no material carried by rivers from the land could reach that far. It is easy to forget the most obvious story in these rocks, that they still lie as they were laid down, still undisturbed after 300 million years. Contrast this with the rock formations just ten kilometres west along the coast where the 600 million year old rocks are now twisted and contorted, the strata often vertical, the result of the clash of continents half a billion years ago. In the soil overlying the rocks there is at least one large granite boulder, carried here from Sligo to the east by a glacier pushing westwards along the coast a mere twenty thousand years ago.

Nor is the headland inactive today. Many of the classic features of marine erosion which can be observed here and at thousands of locations worldwide are ongoing. The power of the waves eat into weak sections of rock forming sea caves. At some stage massive waves blocking the cave mouth and pushing inwards create enormous air pressure inside which forced through cracks and fissures, loosens the strata and causes it to fall into the sea creating a blowhole as here at Poll a’ Sean Tine. Over time, the cave roof collapses leaving a narrow landbridge link to the mainland. When this bridge eventually collapses a seastack remains such as here at Dún Briste. An historical reference to people having to be rescued from such a collapse in 1393 in this part of Mayo (a reference almost certainly to the collapse of Dún Briste) gives some idea of the rapid rate of natural erosion of the headland. Dun Briste is today almost one hundred metres from the mainland and is approximately forty metres by fifteen in area. The remains of two houses survive on the seastack but even more dramatic was a field wall along the western edge with a low gap to allow sheep to pass into another field to the west!

Myth and Legend: the Landscape of the Paranormal

The landscape of the paranormal has a totally different interpretation of these phenomena. St. Patrick came to the headland to confront the pagan chieftain/god Crom Dubh who lived there. Crom Dub attempted to throw Patrick into an eternal fire on the headland but Patrick scratched a cross on a stone, threw it into the fire which collapsed into the sea and is known as Poll a’ Sean Tine, the Hole of the Old Fire. Crom Dub seeing that he had met his match retreated into his fort but Patrick hit the ground with his crozier breaking the ground and leaving the broken fort, Dún Briste isolated from the mainland, where, it is said, Crom Dubh died, eaten to death by midges. This is just one version of many competing legends of Saint Patrick and his adversary at Downpatrick Head. In some stories Crom Dubh is a pagan chieftain, a pagan god, a pirate, a robber. As well as Crom Dubh or Cormac Dubh, the names Geodrisg, Deodrisg and Leodrisg are used. In other stories, Poll a Sean Tine is called Poll a’ Sean Tonna, The hole of the old wave.

The landscape of placenames is interestingly entirely based on the landscape of the paranormal with placenames such as Downpatrick, Poll a’ Sean Tine, Dún Briste all taking their names from legend rather than science. The link to St. Patrick led to the headland being a place of ritual and pilgrimage on one of the four great pre-Christian divisions of the year, the Festival of Lughnasa as it is at Croagh Patrick. The ruin of what may have been a church was associated with the festival held on the last Sunday in July, but two Bronze Age barrows from the second millennium BC located on the headland and also used as part of the Christian ceremonials show that the sacred landscape of such ritual is more than twice as old as the Christian one from St. Patrick’s time.

The Landscape of Military History

There is a landscape of military archaeological and historical remains on the headland with surprisingly far-flung links abroad. A medieval or post medieval promontory fort on the east side of the headland gave the name Dun Phadraig or Patrick’s fort while Dun Briste the broken fort suggests that another fort existed before being lost to erosion (or Patrick’s crozier). Poll a’ Sean Tine was the scene of a tragic loss of life of rebels who had joined the French in Killala in 1798 and who were hiding out on ledges at sea level when the English redcoats were rounding up participants after surrender by the French. The redcoats stayed longer in the area than was expected, a storm blew up and the rebels were drowned in Poll a’ Sean Tine. This place of sanctuary, which had been used as a rebel refuge for decades, was only accessible by ropes.

There are other signs that briefly tell of some human element of the Irish Rebellion of 1798, and the remnants of World War II-era installations, like a small watch house and one of the famous EIRE markers — which at 30 feet tall told fliers they were over neutral territory, and also became navigational cues.

There’s also a large sign where they’d asked local students to write about the legends tied to this place. One story told a lot is about an ogre (or a mean man) that lived here, and how St. Patrick either separated that huge rock with his walking stick or prayed to God to put a barrier between the two. In some of the tellings, the ogre-man starves to death, sometimes he’s still there, sometimes he was eaten by midges. There was another that featured a robber who stole some of St. Patrick’s cattle.

Another story is about how the people stranded on that rock escaped by weaving the thatch from their rooms to vessels down below to rescue them. That seems like a big reach, but better than ogres. Another version has people flying kites up to the stranded people, so that they could haul up rope ladders.

There’s a story about rebels hiding in the blowholes, that one doesn’t end well. If you remember the version of St. Patrick’s story where he led all off the snakes off the island, there’s a telling here that he trapped them all on Dún Briste. One kid said his Grandad told him there is a lobster living under Dún Briste. It tries to eat the lobster pots.

We’re not giants or cattle rustlers, but I would like to go over there. I bet the sunsets look different on that high island. Some local experts took a helicopter trip over there some years back. Apparently that doesn’t happen. Maybe, if we stick around, someone will realize we’re due. We were there for almost 90 minutes, but no one came by to offer us a lift over there.

So we enjoyed the sunset, and then drove into the night, thinking of what we might see tomorrow, and where we would eat tonight.

Céide Fields

A woman that worked at the hotel we stayed at last night insisted we stop by Céide Fields as we went through, and that was good advice. You’ve likely never heard of it, but this is the world’s most extensive Stone Age monument. It’s a system of fields, the remnants of dwelling areas and the megalithic tombs sprawling out over hundreds hectares, and it dates back almost 6,000 years.

This is the oldest such example we have in the archeological record, and it’s worth stopping to consider. The people were managing fields and livestock, six millennia ago. Since we were just learning, at our last stop, about the preservative nature of the bogs, it’s reasonable to think that there were other such places like this … indeed, the thinking is that the techniques used here came with the people as they moved from West Asia through Europe. Here’s an artist’s conception of what it might have looked like.

And here’s a bit of the wall ruins. That little white post is an important marker. The white posts trace the outline of where the archeologists have found the walls.

You can see more of those markers here. We’re walking on this path, but we’re walking right next to one of the walls. They’ve found more than 62 miles of walls, and some of their buildings and tombs. The walls managed cattle, and they were a little more than 3-feet tall. (Even back then, cattle couldn’t jump.) Over the years it got colder and wetter here, and the speculation is that this is what led to the abandonment of the land.

The work is hardly done. There’s a lot of land here to explore, and it’s a manual operation, full of physically probing the earth for the well-preserved evidence of the people that worked on the land. You walk through the visitor’s center, so that you may pay, and they direct you outside into the fields, so that you may see a glimpse of the work. You learn that the composition of the ground means it is a manual and physical exploration.

It didn’t always look like this.

The settlers found woodlands, birch and pine. What they left had been understood in some small way by the locals for at least a century, but it wasn’t until the 1970s that the significance of the place came together for researchers. And while there’s a lot they don’t know, they are still piecing it together.

There’s a great satellite photo that has a graphic showing the rediscovered walls. You can see how the straight lines of the wall remnants continue on beyond the drawn lines. Sometimes they follow the contours of the earth, and sometimes they make the contours. While the weather changed, people would have either moved back or moved off. And if there’s one thing we know its that people will use the resources around them, so some of those old stone fences stayed fences, or the stones themselves might have been repurposed. And it’s all quite interesting.

I asked them if they’d tried lidar, and apparently just last year they’d had some side scanning done. The guy, who really wanted to go home and not answer my silly questions, said they were waiting for more on the results. I should probably set a news alert for that.

But would you like to see the most interesting thing?

This is a tree that fell more than 4,300 years ago. It’s a pine tree. A schoolteacher dug it up just four miles from here, one of the largest bog pines found in the area.

That schoolteacher, Patrick Caulfield, started putting two-and-two together about all of the stones he kept running across while he was cutting turf, for heat. He’d noticed the stones were piled in lines and reasoned that that wasn’t natural. Maybe they were put there by people. Maybe the rocks were there before the bog started to take hold.

His son, Seamas Caulfield, studied archeology, and it was Seamas who started adding some context. There’s some debate about whether all of this is from the stone or bronze age, and so the work goes on, but we are looking at a 4,300 tree. And it’s beautiful.

I wonder what you could make with lumber that is thousands of years old. And now I’ll spend the rest of our trip wondering what I’m walking over in the well-preserved earth.

Sometimes, in thin places, the informed guesses of archeology don’t feel sufficient to tell the story of a place. Imagine, then, how inadequate the rest of us must feel trying to understand or explain it.

An Bhinn Bhuí

We’ve come now to the most northerly summit in County Mayo. It’s called Bhinn Bhuí, or Benwee Head.

There’s a great walk offering a little more than eight miles of views. We don’t not walk the whole thing, but we still got the first views. The whole time we were there we had the place entirely to ourselves. Just us and the wind.

There’s a lot of bogland, a lot of cultural and historical spots to see. We did not do the whole route, of course, but we saw some nice spots.

This place is popular with birders, kayakers and divers.

I don’t think I’d want to dive here. The water moves a lot. And it is probably cold, all of the time. Besides, I could stay on the surface and consider this view all day. Right now, I’m trying to imagine how you find a place like this, and convince someone to let you build a house with giant views like that.

And then, off to the other side, just more giant, beautiful views to consider, at full volume.

If I can’t have a house in a place with views like this, I’ll just have to come back. The ground was soft, inviting enough to consider staying all day, but also wet. It’s called Atlantic blanket bog, and it’s been the prevailing feature of the land for 4,000 years, give or take. The moss on top soaks up moisture, and so its about nine-tenths water. The peat can be acidic and that minimizes the amount of plant decay, it all gets squished down into more peat, and so it is a time capsule, a natural chart of farming styles, volcanic eruptions, and climate change. They say it grows at a rate of about a millimeter a year.

When we come back to places like this we’ll just have to find lightweight chairs and a waterproof blanket.
