Easton's Bible Dictionary (1897)/Tiberius Caesar
Tiberius Caesar I.e., as known in Roman history, Tiberius Claudius Nero, only mentioned in Luke 3:1. He was the stepson of Augustus, whom he succeeded on the throne, A.D. 14. He was noted for his vicious and infamous life. In the fifteenth year of his reign John the Baptist entered on his public ministry, and under him also our Lord taught and suffered. He died A.D. 37. He is frequently referred to simply as "Caesar" (Matt. 22:17, 21; Mark 12:14, 16, 17; Luke 20:22, 24, 25; 23:2; John 19:12, 15).
