Pope Sixtus III (died 18 August 440) was Pope from 31 July 432 to his death in 440.The name of Sixtus is often connected with a great building boom in Rome: Santa Sabina on the Aventine Hill was dedicated during his pontificate and he built Santa Maria Maggiore, whose dedication to Mary the Mother of God reflected his acceptance of the Ecumenical council of Ephesus which closed in 431.Wikipedia
