This is an ongoing project to determine the meaning hidden in an old nursery rhyme.  It is well known that many old nursery rhymes were actually disguised political satires, in the days that overt publishing of government criticism would end in torture and death.

Vintery, mintery, cuttery, corn,
Apple seed and apple thorn.
Wire, briar, limber lock,
Three geese in a flock.
One flew east, and one flew west,
And one flew over the cuckoo's nest.

Vintery                Where wine is made (sacraments? represents the Vatican).
Mintery                Where money is coined (Templars - first bankers).
Cuttery                Where the King could--and did--butcher at will.
Corn                    The wages of a Mason, representing nourishment.
Apple Seed          Two extremes: The healthy fruit, and the dangerous
and Apple Thorn   Thorn apple, Datura Stramonium, "Devil's Weed".
Wire                    Fence to keep people in or out.
Briar                    Same, but natural protection around castle.
Limber                 A two-wheeled cart for moving artillery into position.
Lock                    The ignition mechanism for a gun.
                                Both are preparations for an attack.

Three Birds          King Philip IV, Pope Clement V, and Jacques de Molay,

One Flew West     Pope Clement V to Avignon, to replace the Vatican.

the Cuckoos Nest  The Vatican; 

Some cuckoos are "brood parasites", and lay their eggs in other bird's nests.  After murdering two popes, King Philip had his own sock puppet pope placed in the Vatican, then moved the papacy to Avignon.
