Ole' Buck (TN,KY, NC U.S.A.), The Broad (Gloucestershire UK), Mari Lwyd (Wales-Cymru)

According to the 'Pillars of Tubal Cain' , co-authored by Nigel Jackson and the late Michael Howard, there was a Christmas 'Parade' with a Bull in Gloucestershire (Pronounced Gloster-scheer or shire according to how 'posh' you consider yourself).  'The Broad' was accompanied by a group bearing a Wassail bowl decorated by ribbons and greenery.  They also state that the old Mari Lwyd 'parade' had a leader with a Bull's Head carved on the staff.  I've noticed that a 'woman in black' on the 'youtube' video has a pewter or silver Wren.  The Wren is the winter bird in some Welsh and Cornish folk traditions, while the Robin is the spring/summer bird.  Jackson and Howard hint around that such folk imagery was used in witchcraft to summon the powers of the constellation of the Wain (Wagon), known as the 'Big Dipper' in North America and the powers of Saturn (The Spiritual Attributes/Power of the Planet), ( Roman Saturnalia).
Saturn/Chronos was once considered the Ruler of the Universe in Greek and Roman Mythology.  Under HIS ruler-ship mankind, God(s) and animals were said to be able to communicate freely, thus they were not chained to the 'leaden weight of physicality'.  Later his ruler-ship was changed to the 'modern' characteristics, which were old age, gloom, abandoned places, and death.  He is the same symbolism as the modern Old Man Time before the New Year.
Ole' Buck in North Carolina was said to control the beach, the waves close to the beach, the forest next to the beach and breathe/control fire.  Surprisingly close, to the spiritual characteristics of Bucca in Cornwall.  Jackson and Howard also note that the Bull has been associated with fire, lightning and storm in many myths.  Truly drawing down the Heavenly Dragon into Earth, as the Bull, Serpent, Crocodile and many other animals were described as 'dragons' in the Medieval Period.  Satvrnvs.
