Was Paul in prison in Rome when he wrote many letters to churches he started?

A:

Although attributed to the Apostle Paul, Ephesians was actually written during the eighties of the first century, long after Paul's death. It is known that Paul was imprisoned during his missionary work, and the author of Ephesians mentions Paul's imprisonment to give his epistle a personal touch. A typical method that ancient forgers used to satisfy readers that a writing was genuine, was to include personal details, in this case mentioning Paul's imprisonment. However, Paul did not write this epislte and was dead, not in prison, at the time of its writing.
