It’s later than our period, but I have to agree with Kathy (who sent this in) that it is fascinating.
From The Daily Mail:
It has been sung at carol services across the country but a centuries-old secret political code has been found in a popular Christmas song.
According to one musical expert, O Come All Ye Faithful, also called Adeste Fideles, is actually a birth ode to Jacobite pretender Bonnie Prince Charlie.
Born on December 20 1720, Bonnie Prince Charlie was the grandson of England’s last Catholic monarch, James II.
‘Fideles is Faithful Catholic Jacobites. Bethlehem is a common Jacobite cipher for England, and Regem Angelorum is a well-known pun on Angelorum, angels, and Anglorum, English.
‘The meaning of the Christmas carol is clear: ‘Come and Behold Him, Born the King of Angels’ really means, ‘Come and Behold Him, Born the King of the English’ – Bonnie Prince Charlie!’
Professor Zon said there were other clues to the subversive political message contained in the carol.
