La grotta azzurra
There's a blue grotto in Capri. Statues of pagan gods can be found at the bottom of the cave. After Emporer Tiberius, no one entered it for centuries because fishermen thought it was haunted by evil spirits. A failed german artist August Topisch rediscovered it in 1826, and chains now draw boats inwards. There are almost too many stories to be told, and no I have never been to la grotta azzurra.
This postcard uses a special printing technique: It's been dunked in blue. But it's a shade far darker than any of the emphatic fluorescents I read of on the tourist sites. It has a glazed consistency - the water has always been this still. The reflections themselves are daily reiterations and will be only ever be slight variations of what the walls have already seen. And the postcard is wordless, again.
