How do I show a Views block according to the taxonomy from the node?

I have a site which has articles on it and I'm using the Author module which uses a taxonomy.

I've also created a Author content type to enable Biographies of the authors to be created.

I want to display the Biography of a particular author alongside any Aritcle by that author.

So I have a View that displays the Authors but I need a way for the view to take the Author taxonomy from the node to filter it's result (so it only shows the relavant authors biog).

I suspect this can be done with Arguments but I can't figure out how.

Can anyone help?

I've searched and searched but still can solve the problem.
