In this picture made available by the Vatican newspaper L'Osservatore Romano, Pope Benedict XVI, looks on at two lambs at the Vatican, Wednesday Jan. 21, 2009. The pontiff blessed two lambs whose wool will be shorn later this year to make a shawl for newly appointed archbishops to wear. The blessing Wednesday took place on the feast day of St. Agnes, a martyr of early Christianity who is often symbolized by a lamb. In the ritual, the pope blessed the animals, who were laying down in two baskets, each wearing a crown of flowers on its head. New archbishops receive the wool pallium on June 29. The pallium is a band of white wool decorated with black crosses that is a sign of pastoral authority and a symbol of the archbishops' bond with the pope.Makes perfect sense.
Here’s the explanation:
