A Roman temple to all gods, the Pantheon (not to be confused with the
parthenon, in Greece), as the inscription says, was originally created by Marcus Vipsanius Agrippa, Augustus' right-hand man, between 27 and 25 B.C. in the
Campus Martius. It was rebuilt under the Roman Emperor Hadrian (A.D. 137-38), repaired by Emperors Septimius Severus (r. A.D. 193-211) and Caracalla (r. A.D. 198-217), and then dedicated as a Christian church (Santa Maria Rotonda), by Pope Boniface IV in A.D. 609. The Pantheon is comprised of a huge, domed brick‐faced concrete rotunda (43.3 m. high and wide) and an octastyle (= 8 columns in the end row) Corinthian, rectangular portico (11.8 m. high) with granite columns.
