Hi Jan,
It may be more helpful if you could consider posting some of these
things on the web and including links. Particularly with Fresnel, where
there's code, configurations, and data to consider, it's a bit easier
for the rest of us to understand when we can see what you see.
Some thoughts follow inline.

In combination with excerpt of your Fresnel config below, it appears
you're using the same URI for both the resource you want Fresnel to act
on and the type of the resources your lens is supposed to match.
That is, your eventLens will match anything that has rdf:type
hist:Event, not the actual resource hist:Event (if you wanted to do
that, you would need a domain matching an instance). Without access to
your data, my best guess would be that you should change the resource to
some other URI and assign it rdf:type hist:Event.
You may want to post your sample data somewhere for us to look at. If
you have questions in the future, remember that it's rather difficult
for someone else to evalute a Fresnel config without knowing what you're
applying it to :)

As long as it's a URI it doesn't matter.
