Michael Ledeen adds:

In Naples, for centuries, churches had doors with revolving platforms, through which unwanted babies were delivered to the sisters within. There’s a considerable literature on these abandoned children, who were known as “esposti” or “exposed,” and that is the origin of one of the most common Neapolitan names, “esposito.” Now you know.

In Baghdad they’re called “Callahan.” I’m sure Clint Eastwood is smiling.

He also links to a nice letter from an Aussie. Worth reading.
