Hadrian's wall

I’m a lucky person this month: I’ve seen a lot of ancient Roman ruins. Three weeks ago I was in Pafos where I could see ancient mosaics. Last week I was in Scotland where, remaining roman wall and fortifications are preserved. Romans soldiers probably suffered very much from the weather there… I was exhausted by the wind, even though the Sun was shining, temperature was quite high and there was no rain (my English friend used to say: No rain? Wait a minute…). For no reason my attention was attracted by the remnants of a kind of floor heating: stones supporting the floor, between which hot air flowed. We went for a short walk on Hadrians wall. On the right there was a precipice (Scotland I suppose), on the left a meadow with thousands of sheep.
