That is a great reference! I was hoping someone had some ideas.... the only thing I could come up with was that stollen was served at the Council of Trent-"an ecumenical council of the Roman Catholic Church, held in three sessions between 1545 and 1563 in Trento in Italy. Prompted by the opposition of the Reformation, the council clarified and redefined the Church's doctrine, abolished many ecclesiastical abuses, and strengthened the authority of the papacy. These measures provided the Church with a solid foundation for the Counter-Reformation."

Also, that stollen refers to a post or boundary stone for a city.

Not exactly sure how it relates but I do love his play on words...
