The archbishop normally receives the pallium out of the hands of the Pope. In the past, the journey to Rome to receive the pallium from the Pope openly confirmed the archbishop's allegiance to the Pope.
It is also the name for the Imperial mantle, worn by British monarchs at their coronation.
In the Russian Orthodox Church, the pallium is known as the omophorion, and is worn by bishops and archbishops.
