This is an interesting sculpture at Trinity College in Dublin by an artist named Arnaldo Pomodoro. It is entitled "Sphere Within a Sphere" but from this angle you cannot see the one inside. We walked the campus on a drizzly afternoon.
What a fabulous image, James!
This is so fascinating at the initial experience where it appears that the markings on the concrete surface below were custom designed as part of the artwork to fit perfectly with the lines engraved on the lower part of the steel sphere.
But actually, there are, likely as not no engravings on the steel as it seems to be, instead, mirror polished steel in which we see the reflections of the underlying marks in the concrete!
This idea is very much a parable to how we view each other. The initial impressions are delusional!
Now as to the interior? I will need to meditate further!
Meanwhile be safe on your journey
