The tree is destitute of flowers and foliage till the Griffin comes to it, who plucks nothing from it: “Thus is preserved the seed of all justice” (_Purg._ xxxii. 48; _cf._ our Lord’s words to St. John, Matt. iii. 15). Justice can alone be fulfilled when the Church follows this example of her Divine Founder, and usurps none of the temporal rights of the Empire. After the chariot has been bound to the tree, the previously bare plant breaks out into purple leaves and flowers. The Griffin and his train return to Heaven, leaving Beatrice to guard the chariot of the Church, seated beneath the shadow of the Imperial Tree, upon its root, which is Rome. In a new series of visions Dante beholds the sequel; he sees the conflict of the past, contemplates the corruption of the present, hearkens to the hope of the future. The persecution of the Church by the early Roman Emperors is followed by the inroad of the first heresies; and the donation of Constantine by the rising of the dragon of schism or simony. By more assumption of secular power and dignities, the chariot becomes monstrously transformed, and shamelessly usurped by the harlot, who represents the corrupt ecclesiastical authority enthroned in the place of Revelation, a false and degraded theology based upon the Decretals instead of the true divine science of the Scripture and the Fathers. By her side a giant appears who, after alternate caressing and scourging of the usurper, unbinds the transfigured chariot from the tree, and drags it away through the forest--symbolical of the interference of the royal house of France, ending in the transference of the Papacy from Rome to Avignon.
