Sculpture

On the WBC theme of "Air", a sculpture in Hamilton Palace Grounds by Ian Hamilton Finlay.

It's a circle of slate slabs reading, in sequence:

CYTHERA ~ AIR ~ IN BLUE ~ LEAF ~ BLUE BARK ~ AND BLUE LEAF ~ A LEAF ~ A BARQUE ~ A BLUE LEAF ~ A BARQUE IN LEAF-BLUE ~ AIRE

No idea what it is about.
But apparently Cythera is an island of love or somesuch.
