by undergoing the purgatorial discipline in this life, and the English archives still contain records of certificates given by Edward III. and Richard II. to several illustrious foreigners, testifying to their due accomplishment of the pilgrimage and its attendant rites.[224] I do not know to what authority it was intended that these certificates should commend the recipients. The institution never received the formal sanction, nor even the approbation, of the Church, and in the year 1497 the purgatorial cavern was closed by order of Pope Alexander vi. For some time to come, however, the tradition lived on in various forms: in hagiology, as in the _Aurea Legenda_ of Jacobus de Voragine; in such specimens of popular literature as the story of Fortunatus; in Tassoni’s burlesque poem, _La Secchia Rapita_, and in the tragedy of Calderon, to which it furnished both title and subject. The two points in connection with it that concern us, are the facts that the legend continued the Irish school of the _Fis_, and that it achieved a popularity so widespread and so enduring as to render it almost certain that it must, at least, have come to Dante’s knowledge. A few years before the Vision of Owen, a somewhat similar work had been produced in Italy--the Vision of Alberic, the son of a Campanian noble, and a monk of the famous Benedictine monastery of Monte Cassino. For the most part, this vision is constructed on the conventional lines, but in several of its details it is in such close agreement with Dante’s _Inferno_ as to call for some remark.[225] The commencement, indeed, appears to be original. At the age of ten, Alberic fell into a trance, which lasted for nine days. While in this state he was visited by a dove, which put its bill within his mouth, and carried him to St. Peter, who, in company with two angels, conveyed him to the nether world. On his way thither he passed through the _Limbus infantium_, which also is an unusual feature in works of this class. Among the penalties of Hell which bear a more or less close resemblance to Dante’s _Inferno_, are a valley where the unchaste stood in fire and ice to a greater or less depth according to the gravity of their offence; tyrants and infanticides were enclosed in masses of fire; homicides were plunged in a lake of fire, like blood; breakers of ecclesiastical vows were gnawed by serpents. One purgatorial infliction resembles the punishment of suicides in _Inferno_ xiii.: the souls in question were hunted by a demon, mounted on a dragon, through plains full of thorns and briars, where they left scraps of their clothes and flesh upon the thorns, until, being lightened of their superfluous flesh, they escaped, and were thus purged. Several familiar features reappear, and are, in some measure, reduplicated; thus, besides the bridge, there is a red-hot ladder, which the wicked have to ascend until they drop off; Hell’s mouth again appears as the mouth of a
