Thanks a lot! And sorry about my delayed answer, i thought it would take way longer to get that translated, i didn´t think you´d have Zuntz´s work as a source. Even better than i could have hoped for, the original inscription!
i invested some serious time looking up that paragraph on the net and got no results, though i got to find some "indie" texts and other pdfs on the topic that i didn´t find on my first research, like one by Torjussen: http://uit.no/getfile.php?PageId=977&FileId=613
About Pythagoreanism vs Orphism, i barely got started on the contrast, but that constrast was totally called for because there are references to pythagoreanism almost everytime orphisms is discussed. Thing is, and this is somewhat of an "uneducated" guess (since i haven´t done much reading about pythagoreans, yet) the concept of metempsychosis seems to have existed before the phytagorean bunch and looks like it was introduced later, added to a group of other central theories and ideas about the universe. On the other hand, the begginings of orphism seem to match the apparition of metempsychosis (on greek territory at least) and the death-rebirth idea is not just part of the religion, they are completely fused, religion and concept are completely inseparable.
Though that´s what i could see so far by myself, maybe Ivan Linforth can shed some light on this issue for me.
Again, thanks for the warm welcome and for taking the time to look this up on your books!
