The last question worked so well, I have another:
Maria von Trapp mentioned that, in Medieval monasteries, the O Antiphons helped determine what the monks ate in the days leading up to Christmas.
She mentions that for the antiphon "Root of Jesse," they would eat root vegetables, and for Key of David they served Wine, in reference to the keys held by the monk in charge of the wine cellar.
So, does anyone know the rest? (O Wisdom, O Lord of Might, O Dayspring, O Desire of Nations...)
