After the Gloria in excelsis Deo at the Mass of the Lord's Supper, all church bells are silenced and the organ is not used. The period that lasted from Thursday morning to before Easter Sunday began was once, in Anglo-Saxon times, referred to as "the still days". In the Catholic Church, weddings, which were once prohibited throughout the entire season of Lent and during certain other periods as well, are prohibited during the Triduum. Lutherans still discourage weddings during the entirety of Holy Week and the Easter Triduum.
