Setting off alone along the now familiar route down Henderson Row past a silent Academy, now in break, I savored a sense of purposefulness and anticipated my visit to the Richard Long show at the NGS Modern Galleries, their major exhibition of the year, open for the Festival, and an important one for Long as well. He hasn’t had an exhibition of this size in Britain in over fifteen years. I also relished another walk along the Water of Leith. Crossing unnecessarily over to elegant and brightly sunlit Dean Terrace, I crossed back at the bridge and descended into the path just before St. Bernard’s Well, a sulfurous source discovered in the mid-eighteenth century and decorously enclosed in a pump house designed by Alexander Naismyth, following the circular design of the Temple of the Sibyl at Tivoli, a favorite destination on the Grand Tour. A statue of Hygieia stands within ten Tuscan columns, a sober northern interpretation of the original’s Corinthian order.
