Out in Hilary's Village - you know, the one that she thinks is needed to raise a child - there are more sins than you can shake a stick at. But some are more infamous than others.
The Church identifies some very basic ones, from which endless permutaions can be made.
The Seven Deadly Ones.
The Church also points to 'the occasions' of sin. Times, places, environments that sin is very likely to be found and to ensnare a a young Knight or farm-boy, a Lady or a wench. It was getting beyond high time someone actually tried to identify which places to avoid.

Perhaps someone else might take a look at the rest of the world. The past British Empire used to be illustrated in pink !
