The Chaplet or De Corona - Tertullian,

Keep for God His own property untainted; He will crown it if He choose. Nay, then, He does even choose. He calls us to it. To him who conquers He says, “I will give a crown of life.” Be you, too, faithful unto death, and fight you, too, the good fight, whose crown the apostle feels so justly confident has been laid up for him. The angel also, as he goes forth on a white horse, conquering and to conquer, receives a crown of victory; and another is adorned with an encircling rainbow (as it were in its fair colors)—a celestial meadow. In like manner, the elders sit crowned around, crowned too with a crown of gold, and the Son of Man Himself flashes out above the clouds. If such are the appearances in the vision of the seer, of what sort will be the realities in the actual manifestation? Look at those crowns. Inhale those odors. Why condemn you to a little chaplet, or a twisted headband, the brow which has been destined for a diadem? For Christ Jesus has made us even kings to God and His Father.
