Like professor Beard, I find this utterly amazing. One wonders if there were any other speakers of Aramaic in the area at the time to give the man some mother-tongue company. Again like professor Beard, one also cannot help wondering what language the couple used in their daily life.
Professor Beard's book is called SPQR: A History of Ancient Rome (link is to a review in The Atlantic).
