Simon Peter was crucified in 46 AD alongside James by governor Tiberius Alexander.
Acts 12:1ff reports that only James was executed and Peter survived. This contrasts with Josephus’ report in Ant. 20.5.2, according to which both James and Simon were executed:
… the sons of Judas of Galilee were now slain… The names of those sons were James and Simon, whom Alexander commanded to be crucified.
This raises several questions. 1) Do these texts refer to the same event? 2) When and by whom was the sentence of death pronounced? 3) Did Peter survive? I assume that the simplest explanation is the correct one. The answers follow in the next theses.
