Seen lots on this in previous years. It seems to be an original fake or a fake original.
Although 'ancient' by modern standards, it seems to be several hundreds of years younger than needed to be authentic, either created to sell the 'Jesus meme', original fake, or somehow created independent of the 'meme' but later adopted by believers or scammers, fake original.
Bottom line, at least for me at this time: it is authentic but not Jesus, being created several hundred years later.
