Two minutes of incensing the altar and the chancel party.  Note the smoke rises straight up. Rather noteworthy copes as well, and the length is perfect on all three. A well-cut cope has a hem which will rise as much as four inches shorter as it goes from back to front, which keeps the priest from tripping or treading on it while going up steps. The longest point at the center back should clear the floor. Attendants on each side of the celebrant hold back the front sections of the cope to allow the priest’s arms to move freely with the thurible.  It really is quite a marvel of choreography on the chancel steps.  Note the “boat boy” standing to the far right of the altar with his small brass boat filled with incense at the ready for refilling the thurible.
