Could Jesus Read and Write?

Nearly everyone today assumes that Jesus could read and write. But is that historically plausible? There is only one story in the New Testament where Jesus is shown to be able to read (Luke 4) and he is never said to be able to write (except in the story of the Woman Caught in Adultery that was added by scribes only later John 7-8). In this episode we consider the literacy rates of antiquity (very low!), and discuss who could learn to read and then write, how they were educated, and whether it is likely that an impoverished dayworker from a poor family in a remote backwater of the empire was one of them.
