Probably not Olympian,especially considering where it was found,Olympian is prety much exclusively distributed in the US(though certainly came from somewhere in the old world originally).Some folks have said Osborne Prolific,which I know is distributed in European nurseries, another variety which is often said to be the same is Neveralla/Archipel,although they could just be very similar to Osbornes Prolific and there appear to be confusion on those 3 varieties as to which is actually which,they could all be the same,or there could be 2 figs with 3 names,or even 4 or more sold under 3 names,who knows.
The best thing is to monitor it over a period of time,maybe grow it alongside Osborne Prolific(which is available inside the EU)to see if it is the same.In the meantime you have an interesting unknown fig which produces in Slovakia,which is pretty awesome.
