...a pen used to vote at Conclave:
From Boxing Day until Epiphany, we will be marking the Twelve Days of Christmas by highlighting different objects archived at the archdiocese. (We paid special attention to making the lyrics syllabically consistent with the original tune.)
Interestingly enough, there is a Canadian and Catholic angle to this beloved and much-parodied Christmas carol. In 1979, a Canadian hymnologist, Hugh McKellar, claimed The Twelve Days of Christmas was a catechism song to help young Catholics learn their faith at a time when practising Catholicism was criminalized in England.* For example, he proposed that the four calling (or colly) birds stood for the four gospels and the eight maids-a-milking were code for the beatitudes.
Though there are many theories regarding variations of the song's lyrics and their symbolism, the origins of the hymn remain unknown.
