It takes a while after staring for hours at a screen to see the depths of paintings.
Stopped, to try and focus my thoughts, by a group looking at Caravaggio Supper at Emmaus.
This was Caravaggio's last work, painted in 1601, before he went on the run after allegedly murdering a pimp. Perhaps he was himself a pimp, said the guide, we don't know. He certainly liked the night.
"Do we all know about the supper at Emmaus?" she asked.
I thought I did but of course I do not. Make so many assumptions - that all the Bible stories are lodged very firmly in the mind because they were taught at such an early age. They're not.
I had completely forgotten that this was the moment when Christ appeared to his friends after his crucifixion.
He had been walking with them and they had not recognised him.
