It's very interesting to see that traditional method of making those tiles by hand.
One other thing that I found interesting is that those oxen are females, cows. Most often the oxen is a castrated male, but cows and even bulls are sometimes trained to work. Those two cows were stout and gorgeous.
These are a landrace known as Arouquesa. They are triple purpose, for milk, meat and work. Which probably explains why I got away with approaching this close to them. I'm generally pretty nervous about approaching any bull, let alone a finely built one that suggests it's a dairy breed. These guys seemed pretty placid, but I decided this was close enough as the girl in background had noticed me and I didn't want to attract the attention of that boy in the front. His horns look kinda spiky and I bet he can run faster than I can!
We stopped for a picnic there and this one came over to see if we had any treats for her - she was really friendly!
If you look on the right hand side near the tip of her horn, you can see the two from the other photo - it looks like the bull did finally haul himself to his feet after I'd taken his photo.
And here she is making friends...
It's interesting how I interpreted their shape as 'dairy' and you interpreted it as 'fighting' or 'auroch-like'. I guess it's that they are an old race, not developed for heavy muscling for the meat industry and we each interpreted according to our own past experiences. Isn't there a saying about how "we see and understand things not as they are but as we are"?
