Six geese a-layin’ somehow symbolise the six days of creation. The prologue of the fourth gospel draws strong identification of the Logos, Christ, with the beginning of all things. Somehow geese invite contemplation of how even the absurd fits into the matrix of all that is.
Sixth day of Christmas
Geese and ganders proud parade
sound forth creation.
The music of the spheres and amusement of odd creatures sing glory
