Acts 27:1

That we should fail— Prisoners of importance used frequently to be sent, as from other provinces, so from Judea, to Rome. Julius was very probably a freed-man of the Julian or Caesarean family, for freed-men bore commonly the names of their masters who gave them their freedom. He was centurion of a cohort belonging to the legion called Augustus's legion. Lipsius mentions the inscription of a stone which notices that legion. See Lipsius in Tacit.
