During the week, I blogged about the tomb of Bartolomeo Sacchi, also known as Platina and asked for help in translating the Greek inscription. Anyway, I've taken another picture of the Greek (click to enlarge) which should help any friendly 'Grecian' (thanks Petellius!) to translate it.
I also thought I'd share with you this marble relief (Lirioni, c.1730) which is on one's left as one enters the Basilica.
It commemorates the attempted assassination of Pope Marinus I (882-884) during Mass. However, as soon as the assassin crossed the threshold of the church he was stricken blind and rendered incapable of fulfilling his task.
