Billy Pitt had them built, Buck Mulligan said, when the French were on the sea. But ours is the omphalos.
James Joyce spent six days staying with a couple of friends in a Martello tower in Sandy Cove, Dublin, in 1904, and later set the first chapter of his novel Ulysses there. Built during the Napoleonic era as a defensive position against a feared French invasion, the tower is one of a string of Martello towers in England, Ireland, and Wales.
Now known as the James Joyce Tower, it has been made into a museum, and furnished as it was during Joyce’s time there. For Joyce devotees who make the pilgrimage to visit it, the tower may indeed be an omphalos, a sacred conical object.
