Was this story the legend or the consequence of an invocation of Saint Pirmin against unwholesome drinks? Besides people recommended themselves to this saint against the plague and the consequences of dangerous food. Furthermore, his dalmatic and his cincture were considered powerful to assuage the sufferings of pregnant women. An ancient seal of Saint Pirmin is found with these two verses used in certain provinces of Germany:
"Sanctificet nostram sanctus Pirminius escam,
Dextera Pirmini benedicat pocula nostra."
Saint Samson, Bishop of Dol, in Brittany; 28th of July, about 564. Some say he slew a dragon, and Father Cahier says this may be symbolic of the many victories he gained over the enemy of men. According to several, it was a serpent which he drove from a grotto on the banks of the Seine (Cf. Longueval, Histoire de l'Eglise gallicane, livre IX.)
Saint Mellon (Mélon, Mellonus, Mallonus, Mello, Melanius?) first Bishop of Rouen; 22d of October, about 214. A serpent of which his legend speaks may be only the dragon of the saints who preached the Gospel to idolatrous nations. An old office of his says:
"Manum sanat arescentem
Morsum curat, et serpentem
Sese cogit perdere."
His legend further relates that he overthrew in the city of Rouen the idol Roth, and that the devil complained to him of the trouble he had caused in his empire. (AA. SS. Octobr., t. IX., p. 572, sq.)
Saint Cado (or Kadok, Cadout, Cadog, Catrog-Doeth, Cadvot), bishop and martyr in Brittany; 1st of November, about 580. The Bretons relate that on a little island off the coast of Vannes, between Port-Louis and Auray, he drove the serpents away and they never appeared there again (Vie des Saints de la Bretagne, p. 666). The island retains the name of Enis-Cadvod or Inis-Kadok, that is, the island of Saint Cado.
A Saint Paternus, bishop, whom Father Cahier cannot locate, is mentioned as having warded off the bites of serpents. He cannot say, too, but that there is more of symbolism than of real history in the story.
Saint Peregrinus, bishop, martyred at Auxerre, 16th of May, third century, driving out serpents. Though one may consider this representation a manner of expressing the earnestness he displayed in extirpating idolatry from the people of Auxerre, it is admitted that in the Nivernais country (especially at Bouhy where he took refuge), serpents are never seen. People even come to the church of that village to take earth out of a hole habitually dug ad hoc; and that earth is carried away as a preservative against the bite of reptiles. It is besides regarded as an understood fact at Bouhy that a certain family there always has the figure of a serpent on the body of some one belonging to it. They are, according to the story, the descendants of a pagan, who, striving to drive the saint away by hitting him with a whip, saw the lash change into a serpent which "landed" near the rock where Saint Peregrinus had sought refuge against persecution.
Saint Honoratus of Arles, or of Lerins; 16th of January, about 430. When he retired into the island which still bears his name, near the coast of Provence, vainly was it represented to him that it was a receptacle of venomous animals. The man of God exactly wanted a shelter, a refuge from all visitors, and drove out all the serpents which had long multiplied there without any obstacle. A palm-tree is still shown there, on which, it is alleged, our saint waited until Heaven came to his aid, by having the waves sweep away all that "vermin" which had rendered the island uninhabitable until then. (Surius, 16 Januar.; and AA. SS. Januar., t. II., p. 19.) Observe that the islands of Saint-Honorat and Sainte-Marguerite are held in that country to have formed but one in olden days, which was the real Lerins, Pliny and Strabo to the contrary notwithstanding.
