19 February

19 February The first Sunday of Lent, known as Invocabit from the first word of the Introit, is for the Greeks a commemoration of the veneration of images (19 Feb., 842). For Gaul it was the jour de bures or fête deu brandons and for Germany Funkentag or Hallfeuer, because on that day the young people ran about the streets with burning torches (Nilles, II, 102). http://www.newadvent.org/cathen/12589a.htm
