If you are visiting Glasgow this summer be sure to visit the Glasgow Boys exhibition. Kelvingrove Art Gallery and Museum has brought together 100 oil paintings from private and public collections across the world for the first major exhibition devoted to these artists since 1968.

The most striking picture? For me it was The Druids - Bringing in the Mistletoe, 1890 by George Henry and Edward Hornel which shows Celtic priests in ceremonial robes descending a steep hillside from a sacred oak grove. The horns of the white wild cattle are decorated with mistletoe, a plant that the Druids believed had magical as well as medicinal properties. What would the world be without magic?
