I have the photograph to prove it: I have visited Limbo, or rather the Piazza del Limbo.
This handsome courtyard indeed seemed a site of perfect natural happiness, especially with a gelato in hand; a decent hotel fronted onto it also.
Alas, the adjoining church of the holy Apostles was securely locked and barred: the gate of heaven was closed.
(The piazza was originally the place to which, in unhallowed ground, the bodies of babes who died without baptism were consigned. I imagined beneath the flagstones a multitude of tiny bones.)
Disappointingly for my own private heresy, I found no Anglican tourists in Limbo...
