The Talbot Rice Gallery (see posts here and here) is housed in part of the Old College, Edinburgh.

On the way out I happened upon a War Memorial to the former alumni of Old College, set into the wall behind its entrance facade

From side. War Memorial wreaths behind:-

I could not get the whole of the memorial into one photo. Nor indeed two. Both of those below are stitches of two.

War Memorial Wall 1914-1918 names. Dedicated “MCMXIV To the glorious memory of the alumni of this University who fell in the Great War MCMXIX.”:-

World War 2 names. Stones to side inscribed 1939 and 1945:-

Several of the exhibits at the Talbot Rice Gallery, Edinburgh, when we visited in February featured circles of different sorts, mostly of natural origin, but some not:-

Thios one has a depiction of Copernicus’s heliocentric solar system in the book at the centre:-

This was on the wall. It looks like the trace of an eccentically orbiting comet or something of that kind:-

Liesegang Rings. I confess I had only heard of Liesegang Rings in a chemical context before this but I now know they occur geologically too, as evidenced below:-

In February my eldest son and his wife (along with our grandaughter) took us to the Talbot Rice Gallery in Edinburgh, which I don’t recall visiting before.

I was taken by this by Angelica Mesiti which contrasts a natural piece of marble with a sea atlas from 1675:-
