The last few weeks have been spent in re-reading Modern English Painters, by John Rothenstein. Published in 1952 it is an interesting book, and although in some ways out of synch with current thinking it sets out values which whilst being very personal, would be worthy of reappraisal.
I was shocked at my lack of knowledge of some of the painters included, but found that I wanted to think more about them as a result - my own Shock of the not so new and not new at all.
In addition to this, another expansive read has been Still Life with a Bridle, Zbigniew Herbert, published by Ecco Press. One of those collections that one can return to often.
