The "rich man" referred to was apparently Joseph of Arimathea, a merchant who is in some tellings also the uncle of Jesus, who once went with him on a trading voyage to Great Britain. This legend is the source of the William Blake poem

And was the holy Lamb of God
On England's pleasant pastures seen!
Set to the stirring music of Sir C.H.H.Parry, this tune, "Jerusalem," is now proposed by a growing number of Britons as the new National Anthem.
