"There should be no need to remind the reader of the famous story of how at the baptism of Clovis a crystal phial was brought down from heaven with the chrism for the anointing of the King, and how every French King down to the ill-starred Louis XVI was anointed at his coronation with chrism into which a small fragment of the solidified oil of Clovis was mixed."
I've looked at the vestments worn by the clergy at the coronation of Charles X; as I did so I couldn't help wondering with what Louis XVI and Charles X were anointed; because, possibly, Robespierre and his buddies and his successors may not have been over-sedulous about the careful protection of the fabled and historical Oil of Clovis. Did they simply make do with (or get the pope to help make special provision) the 'ordinary' Oil of Chrism?
A similar problem was to arise in England.
