“And when they arrive before the Cross the daylight is already growing bright. There the passage from the Gospel is read where the Lord is brought before Pilate, with everything that is written concerning that which Pilate spake to the Lord or to the Jews; the whole is read.
Then a chair is placed for the bishop in Golgotha behind the Cross, which is now standing; the bishop duly takes his seat in the chair, and a table covered with a linen cloth is placed before him; the deacons stand round the table, and a silver-gilt casket is brought in which is the holy wood of the Cross. The casket is opened and (the wood) is taken out, and both the wood of the Cross and the title are placed upon the table. Now, when it has been put upon the table, the bishop, as he sits, holds the extremities of the sacred wood firmly in his hands, while the deacons who stand around guard it. It is guarded thus because the custom is that the people, both faithful and catechumens, come one by one and, bowing down at the table, kiss the sacred wood and pass through.”
