According to the best available information, the shipwreck occurred in the year 56 A. D., and late in the autumn of that year Paul reached Rome as a prisoner. The length of his stay is uncertain. Acts 28 -30 says two years, and the author probably knew. It is probable that Paul was then set at liberty and made another preaching tour, going farther west than before. He was afterwards again seized and taken back to Rome. How long a time elapsed between his second arrival and his execution there no one knows.
