In spite of its utter unreality Nerto is a charming tale, written in a sprightly vein, with here and there a serious touch, reminding the reader frequently of Ariosto. The Devil, the Saints, and the Angels figure in it prominently; but the Devil is not a very terrible personage in Provence, and the Angels are entirely lacking in Miltonic grandeur. The scene of the story is laid in the time of Benedict XIII, who was elected Pope at Avignon in 1394. The story offers a lively picture of the papal court, reminding the reader forcibly of the description found in Daudet's famous tale of the Pope's mule. It is filled throughout with legends relating to the Devil, and with superstitious beliefs of the Middle Age. It is not always easy to determine when the poet is serious in his statement of religious belief, occasionally he appears to be so, and then a line or so shows us that he has a legend in mind. In the prologue of the poem he says:—
"Crèire, coundus à la vitòri.
Douta, vaqui l' endourmitòri
E la pouisoun dins lou barriéu
E la lachuslo dins lou riéu."
To believe leads to victory. Doubt is the narcotic, and the poison in the barrel, and the euphorbia in the stream.
"E, quand lou pople a perdu fe,
L'infèr abrivo si boufet."
And when the people have lost faith,
Hell sets its bellows blowing.
Then later we read: "What is this world? A wager between Christ and the Demon. Thousands of years ago he challenged God, and when the great game began, they played with great loose rocks from the hills, at quoits, and if any one is unwilling to believe this, let him go to Mount Léberon and see the stone thrown by Satan."
So we see that the theology was merely a means of leading up to a local legend.
The story is briefly as follows: Nerto, like all Mistral's heroines, is exceedingly young, thirteen years of age. Her father, the Baron Pons, had gambled away everything he owned in this world, when she was a very little child, and while walking along a lonely road one night he met the Devil, who took advantage of his despair to tempt him with the sight of heaps of money. The wretched father sold his daughter's soul to the Evil One. Now on his death-bed he tells his child the fearful tale; one means of salvation lies open for her—she must go to the Pope. Benedict XIII is besieged in the great palace at Avignon, but the Baron knows of a secret passage from his castle leading under the river Durance to one of the towers of the papal residence. He bids Nerto go to seek deliverance from the bond, and to make known to the Pope the means of escape. Nerto reaches the palace at the moment when all is in great commotion, for the enemy have succeeded in setting it on fire. She is first seen by the Pope's nephew Don Rodrigue, an exceedingly wicked young man, a sort of brawling Don Juan, who seems to have been guilty of numerous assassinations. He immediately begins to talk love to the maiden, as the means of saving her from the Devil, "the path of love is full of flowers and leads to Paradise." But Nerto has been taught that the road to Heaven is full of stones and thorns, and her innocence saves her from the passionate outburst of the licentious youth. And Nerto is taken to the Pope, whom she finds sadly enthroned in all his splendor, and brings him the news of a means of escape. The last Pope of Avignon bearing the sacred elements, pourtant soun Diéu, follows the maiden through the underground passage, and escapes with all his followers. At Château-Renard he sets up his court with the King of Forcalquier, Naples, and Jerusalem and Donna Iolanthe his Queen. Nerto asks the Pope to save her soul, but he is powerless. Only a miracle can save a soul sold to Satan. She must enter a convent, and pray to the Saints continually. The Court is about to move to Arles, she shall enter the convent there. On the way, Don Rodrigue makes love to her assiduously, but the young girl's heart seems untroubled.
At Arles we witness a great combat of animals, in which the lion of Arles, along with four bulls, is turned loose in the arena. The lion kills all but one of the bulls. The fourth beast, enraged, gores the lion. The royal brute rushes among the spectators and makes for the King's throne. Nerto and the Queen are crouching in terror before him, when Don Rodrigue slays the animal, saving Nerto's life. Nay, he saves more than her life, for had she died then she would have been a prey to the flames of Hell.
