Then takes place the elaborate rite of the choosing of the Lamb: while the congregation sing 41 times the Kyrie eleison, the priest checks the wine and chooses among the bread one loaf which will be consecrated (the "Lamb"). The Lamb is cleaned with a napkin and blessed with the priest's thumb wet with wine. Afterwards the priest takes the Lamb in procession around the altar and the deacon follows with the wine and a candle. At the altar, the priest, with appropriate prayers, blesses the Lamb and the wine, places the Lamb on the Paten and pours wine and a few drops of water in the chalice (the chalice is placed on the altar in a wooden box named "ark").
