If you attend the mass of the pilgrim, at noon, you will see rocking(tossing) under vaults an enormous censer of silvery, high brass of 1,60m and weighing more of 50kg. It is the botafumeiro to the spectacular oscillation, that amounts in more of 20m of height to mean shaving the ground in a 68 kph speed by leaving behind him a fine trail of smoke and incense. A team of eight men(people), tiraboleiros, activates the rope which commands(orders) the movement of the botafumeiro. This rite, one of the most popular of the cathedral, continues probably for 700 years, in sign of spiritual purification. The current censer dates the environment(middle) of the XIXth century.
