It’s rare, but much more interesting, to find serious museums who are willing to take a focused look at art of particularly local interest rather than seeing yet again the same handful of artists who are fashionable at the moment throughout international art circles. I saw fascinating exhibits in July at The Dublin City Gallery The Hugh Lane and Project Arts Centre of two generations of artists whose themes are Irish national identity (not individual identity, as was of interest to Americans since the 1980s) during periods of change.
