FOUR VIRTUES

I was puzzled by this as it did not fit with the rest of the imagery in the interior of the Abbey
A friendly guide at Buckfast Abbey then told us the origin of this piece of iron sculpture.
It was made by a German Jew during the Second World War in gratitude to the Benedictine monks who offered him sanctuary for the duration of the war.
Can you identify the Four Virtues ? It took us a bit of time.
