Jacopo Torriti, The Annunciation
Apse, Basilica of Santa Maria Maggiore, Rome
God's mouth emits the spiritus sanctus, punningly the Holy Spirit and "holy breath." Strikingly, God is pictured not as a hand or an old man but as the Son. Below, Gabriel greets Mary with the blessing gesture and she responds with a gesture that one historian says means reserve and detachment.
