I was reading a translation of Josephus many years ago that mentioned the tzitz (the crown of the high priest with Qdosh Yisrael engraved on it). The commentary to this Josephus said that the tzitz was written in Paleo Hebrew and this had been confirmed because the tzitz had only gotten lost much later after the destruction of the temple and so people had written descriptions of it.
Unfortunately I don't have access to this Josephus anymore, and I have tried googling to find out when the tzitz was lost and where it was being kept but I can't find any information. Does anyone here have any knowledge? Obviously if the tzitz was written in Paleo it would have religious significance.
