Question: what does it say on the front of the pantheon

title: Pantheon, Rome
text: The third niche has a sculpture by Il Lorenzone of St Anne and the Blessed Virgin . In the third chapel is a 15th - century painting of the Umbrian school , The Madonna of Mercy between St Francis and St John the Baptist . It is also known as the Madonna of the Railing , because it originally hung in the niche on the left - hand side of the portico , where it was protected by a railing . It was moved to the Chapel of the Annunciation , and then to its present position sometime after 1837 . The bronze epigram commemorated Pope Clement XI 's restoration of the sanctuary . On the right wall is the canvas Emperor Phocas presenting the Pantheon to Pope Boniface IV ( 1750 ) by an unknown . There are three memorial plaques in the floor , one conmmemorating a Gismonda written in the vernacular . The final niche on the right side has a statue of St. Anastasio ( 1725 ) by Bernardino Cametti .
