Thursday 19 September is St Januarius Day in Italy where a crowd in Naples waits to see his blood liquify.

But in England it’s more observed as St Theodore of Canterbury Day.

Theodore was a Greek, born in Tarsus, who became Archbishop of Canterbury in the 7th century.

He came to Hertford in 673 to hold a reforming Synod which sorted out the date of Easter. There is stone recoding this outside Hertford Castle.

He died on 19 September 690 and is buried in St Augustine’s Abbey in Canterbury.
