"he avoided sight and conversation of women affirming this to be the work of the devil"
You do have to wonder if this ban had something to do with that.
Henry, so history tells us, hoped to curtail the spread of the pestilence that was running rampant throughout his kingdom at the time, he was certainly not an idiot, he was well read - so did he understand the science behind the spread of the diseases? - It's unlikely.
The ban was bound to fail of course, how did he think it could be implemented.
