Last autumn, having just arrived in Florence, I was walking through the city with some colleagues of my wife, all Renaissance scholars. Noticing the glass façade of the restaurant Alle Murate, I remarked, ‘Oh, that's where it is.' ‘Have you not been there yet?' they answered in unison. ‘No, have you?' I replied. ‘Yes, we went last week.' ‘How was the food?' I inquired.
