Ludus is from the Latin. 
This looks like maybe it's part of a Ph.D dissertation.

Answer

It is not clear.  Probably both but then goes onto say "is" which suggests you are looking for only one.  I conclude that I have no idea.  I would have to ask the author.

The whole sentence is just so unclear, it has either been writen by a non-native or by someone who wants to ensure zero clarity.  Interesting challenge.  Even if there is some obscure grammar rule that explains this, I suspect the majority of natives would no know for sure.
