The second proposal is pagan origin

The second proposal is pagan origins for the custom of rolling objects down the hill. It is thought that bundles of burning brushwood were rolled down the hill to represent the birth of the New Year after winter. Connected with this belief is the traditional scattering of buns, biscuits and sweets at the top of the hill by the Master of Ceremonies. This is said to be a fertility rite to encourage the fruits of harvest.
