Since the forum apparently won’t let me reply to Professor Nikolaev below, I’ll post here instead.
I understand that you want to discuss the text. But since you have absolutely no assurance so far that the text is even authentically ancient, let alone actually Sappho, because NOTHING IS KNOWN ABOUT THE FRAGMENT’S ORIGINS, such discussion seems premature.
As for this not being Dr. Obbink’s forum, I think I’ve already mentioned that it has been impossible to get him to respond in any manner. This seems as good a place as any to discuss important problems.
