The Honeymoon...it has been said that the origins of this word date back to the times of Babylon but it was surely a medieval custom.  Along with the charivari tradition on the Wedding Night, fertility and its ensuing fruit were the first order of “busy-ness” after the Wedding.  In order to increase the virility and fertility of the newlyweds, the father of the bride would provide his son in law with all the mead (a honey-based drink) he could drink during the first month of the marriage (and therefore "moon"). This kept him less involved with the affairs of the men, and focused on his new wife for that first ovulation–or moon-- cycle after the consummation of the vows.
