On the writing of blogs

This month gwallter is ten years old, and this is his 598th blog. It seems a good time to look back and reflect on his progress so far. When I started in 2013, blogs were still quite fashionable, and I felt some pride in joining a fraternity of online scribblers. Nowadays, you often have the […]
Afon ar ei gwely angau

Y peth mwyaf trist am ein taith gerdded llynedd ar hyd Llwybr Afon Gwy, o Gas-gwent i Bumlumon, oedd Afon Gwy. Hynny yw, cyflwr amgylcheddol Afon Gwy. Y gwir blaen – gwir na allai neb ei wadu erbyn heddiw – yw bod yr afon yn prysur farw. Roedd yr arwyddion yn amlwg, hyd yn oed […]
A Dada excursion

Recently, while considering the prehistory of walking as an artistic activity, I came across a Dada event, held in Paris just over a century ago, that stands […]

The publication of ChatGPT, which can respond in a conversational and explanatory way to natural language queries, has set teeth on […]
Sarn Helen, end to end

Several stretches of Roman road in Wales are labelled ‘Sarn Helen’. The one Tom Bullough sets out to walk, in a roughly straight line except for a lurch eastward to Brecon Gaer, is the road that leads from the fort at Nidum (Neath) to Canovium (Caerhun, near Conwy). He has recorded his trip in a […]
How do you do?

When you meet someone new, and especially when you know you might be spending a long time in their company in future, how do you begin the relationship? Do you try to prime yourself by asking others beforehand? When you meet, what do you say about yourself, to give the other person an idea of […]
A port painter

The Glynn Vivian Art Gallery has got into the excellent habit of displaying a good mix of works from its permanent collection along a long wall in one of its upstairs rooms. This has the advantage of letting us see paintings that would not otherwise often see the light of day. When I was there […]
