A photograph of bishops at the Second Vatican Council. Most

A photograph of bishops at the Second Vatican Council. Most are wearing purple mantelletta over the rochet and purple choir cassock. On their heads are the zucchetto and purple biretta. Most seem to be wearing the pectoral cross on the chain, rather than the green and gold cord that would be more proper for choir dress. In the background, one can make out the scarlet of a Cardinal, whose biretta is tuftless and who wears the scarlet mozzetta over his mantelletta. You can also make out two bishops in blue, rather than purple. These are religious order bishops -- Franciscans, I think. Also in the background, two prelates in the wide-brimmed saturno.
