Christian faith improved on the simplicity of pagan devices, and was able, through the intermediation of men of supreme sanctity, to induce Heaven to render the ordeal still more miraculous. D’Achery quotes from a contemporary MS. life of the holy Pons, Abbot of Andaone near Avignon, a miracle which relates that one morning after mass, as he was about to cross the Rhone, he met two men quarrelling over a ploughshare, which, after being lost for several days, had been found buried in the ground, and which each accused the other of having purloined and hidden. As the question was impenetrable to human wisdom, Pons intervened and told them to place the ploughshare in the water of the river, within easy reach. Then, making over it the sign of the cross, he ordered the disputant who was most suspected to lift it out of the river. The man accordingly plunged his arm into the stream only to withdraw it, exclaiming that the water was boiling, and showed his hand fearfully scalded, thus affording the most satisfactory evidence of his guilt.[902] St. Bertrand, Bishop of Comminges, adopted a similar method in a case of disputed paternity. A poor woman came to him with a starving infant, which the father refused to recognize or provide for, lest such evidence of sin should render him ineligible for an ecclesiastical benefice. The bishop summoned the offender, who stoutly denied the allegation, until a vessel of cold water was brought and a stone thrown in, when the bishop blessed the water, and ordered the father to take out the stone, saying that the result would show the truth or falsity of his asseverations. Full of confidence, the man plunged in his hand and brought out the stone, with his hand scalded as though the water had been boiling. He promptly admitted his guilt, acknowledged the child, and thenceforth provided for it.[903] Similar to this was the incident which drove the holy St. Gengulphus from the world. While yet a warrior and favorite of King Pepin, during his travels in Italy he was attracted by a way-side fountain, and bought it from the owner, who imagined that it could not be removed from his possessions. On his return to France, Gengulphus drove his staff into the ground near his house, in a convenient place, and on its being withdrawn next day, the obedient stream, which had followed him from Italy, burst forth. He soon learned that during his absence his wife had proved unfaithful to him with a priest, and desiring to test her innocence, he took her to the fountain and told her that she could disprove the reports against her by picking up a hair which lay at the bottom of the pool. She boldly did this, but on withdrawing her hand it was fearfully scalded, the skin and flesh hanging in strips from her finger-ends. He pardoned her and retired from the world, but she was implacable, and took her revenge by inciting her paramour to murder him.[904]
