The picture on the left is of St Benedict's Chapel. The central figure is of him holding his book of rules. He has his finger to his lips to emphasise the value of listening. Legend has it that the other monks didn't like him much and tried to murder him. One attempt was with a poisoned cup of wine, but as he was about to drink it a snake came out of it and broke the chalice....strikes me that is a better way of putting people off drinking than unit pricing of alcohol.A second attempt was made with poisoned bread but Benedict's pet raven flew in and took the loaf from the table and made off with it. Images Of Benedict often include a raven and a broken chalice.
The Reredos in the middle picture was intended to be painted. But until the 1960s was left as plain alabaster. It was then painted using the original planned colour scheme
The right hand picture is the Lady chapel
