The extant manuscripts of the writings of the 1st-century Romano-Jewish historian Flavius Josephus include references to Jesus and the origins of Christianity. Josephus’ Antiquities of the Jews, written around 93–94 AD, includes two references to the biblical Jesus Christ in Books 18 and 20 and a reference to John the Baptist in Book 18.
Some have called these later insertions into Josephus’ works. Just saying, but they do seem a little awkward given the surrounding text.
Tacitus also?
