Reply To: What did people do before Rashi invented Rashi tefillin?

ubiquitin: Thanks for your input although it does little to resolve the puzzle. On virtually every question in halacha, we know what the two sides maintain and we decide as per one side. Once this is decided,one does not go back and question an established fact. IN the questyion of tefillin, what was the decision,say,in the Tano’ims time? Amoro’im? Unless we accept that this question goes back to-at least- the “golus bovel”, it is a puzzle how one did not just look into the tefillin of one’s parent and do the same. According to what you write, this machlokes goes back to very early days and this is truly a puzzle.
