The first sentence of the Zueignung in the beginning of Goethe's Faust, Eine Tragödie reads thus:
Ihr naht euch wieder, schwankende Gestalten!
I am interpreting this as something along the lines of "Again you come, shifting forms!" I'm operating under the notion that euch is here being used as some manner of second-person plural pronoun, possibly the Dative.
That leaves me with two questions: 1. What is the specific grammatical classification of this use of euch 2. If I am right about what it is, why is a second pronoun being employed for the same entities for an intransitive behavior?
