Melpomene Revisited

You will remember Melpomene, the Muse of Tragedy who graces the rectory garden. I encountered Melpomene again on my walk around London today. On the Guilford Street frontage of Great Ormond Street Hospital in Bloomsbury is what looks like a 1930s frieze depicting the Nine Muses. Why on earth this should be on the outside of the Hospital buildings I can't imagine (there isn't a Muse of Medicine), but here is the Melpomene there anyway.
