I was trying to work out last night exactly when this older civilisation came to an end- and the answer has to be different for different countries. In Southern Europe, according to Burkhart, things changed for ever in 1336 when the poet Petrarch climbed Mont Ventoux for fun. In England there are two events that serve as possible markers: the battle of Bosworth Field in 1485- which brought our first renaissance monarch to the throne, and the dissolution of the monasteries- which got under way in 1536. I incline towards the earlier date.
I love Tudor things and Jacobean things and 17th and 18th century things- but they don't have the otherness and strangeness of medieval things. They belong to our current civilisation. They are modern.
