T. F. Thiselton-Dyer, Folk-lore of Shakespeare
“ There can be no doubt that the title of Shakespeare’s play, “Twelfth Night,” took its origin in the festivities associated with this festival. The season has, from time immemorial, been one of merriment, “the more decided from being the proper close of the festivities of Christmas, when games of chance were traditionally rife, and the sport of sudden and casual elevation gave the tone of the time. ”
