The tradition of Marian veneration was greatly expanded only with the affirmation of her status as "Theotokos" in 431. The mosaics in Santa Maria Maggiore in Rome, dating from 432 to 40, just after the council, does not yet show her with a halo. The iconographic tradition of the "Theotokos" or Madonna (Our Lady), showing the Virgin enthroned carrying the infant Christ, is established by the following century, as attested by a very small number of surviving icons, including one at Saint Catherine's Monastery in Sinai, and Salus Populi Romani, a 5th or 6th-century Byzantine icon preserved in Rome.
