Satan had a deadly hatred against St. Dominick, and often endeavoured to destroy his soul and body. St. Donatus was another mark at which the devil shot his fiercest arrows; but a man who raised the dead, as this saint did, did not stand in fear of an evil spirit. St. Donatus raised to life a woman that died suddenly without informing her husband where she had concealed a sum of money belonging to him. From the mouth of the grave the resuscitated woman told where the treasure lay. A dishonest creditor was proved to be a false swearer and cheat by a corpse endowed with speech by St. Donatus.

St. Cyriacus, St. Largus, and St. Smaragdus drove evil spirits not only out of afflicted persons, but out of the country. Cyriacus, in particular, was so famous for his power over evil spirits, that princes in distant lands solicited his assistance to banish the demons to their own peculiar place of torment.

The holy virgin, St. Clare, though a feeble woman, fought and prevailed over the devil that came to her in the form of a black man.

St. Bernard cured persons possessed of devils, and he performed miracles with a crook of St. Cæsarius. The former used his staff as a miracle-working instrument.

St. Giles was miraculously preserved by a hind sustaining him with her milk in a cave; and such was the saint's care over the helpless animal, that on two occasions he drew a line on the ground over which a pack of hounds chasing the hind could not pass, although there was nothing visible to restrain them.

St. Euphemia had her guardian angels that protected her from the violence of her enemies, who sought to burn her in an oven full of pitch, brimstone, and tow. She came out of the oven unhurt, but two men who laid hands on her were consumed by the flames. Wild beasts refused to devour her in their dens, and iron lost its force on her. St. Euphemia's time came however, and she met her fate as a martyr with Christian fortitude.

St. Francis' spirit appeared in a chariot of fire, sweeping through the air. Over a city distracted by factions and civil broils, he saw the devils very jocund, blowing the fire of discord. With a loud voice he commanded the spirits to depart; they obeyed him, and the city was restored to peace and concord.

St. Bridget possessed the faculty of witnessing angels, and enjoyed the privilege of having them for her companions; nevertheless, she had to sustain many conflicts with the devil. One time she saw Satan in a dreadful shape, with a hundred hands and as many feet. Terrified, she fled from the horrid monster and took shelter near a holy relic, where she was safe. In a sad hour of affliction the spirit of St. Denis appeared to her, and told her he would be her protector ever afterwards. She certainly, if report be true, turned out to be a saint endowed with extraordinary power, which enabled her to give sight to the blind, hearing to the deaf, speech to the dumb, and health to the sick; and, moreover, we are informed that she raised ten dead persons to life. On account of these miracles, and for her most holy life, Pope Boniface IX. canonised her, and put her in the number of the saints.

St. Gregory of Tours recounts numerous miracles wrought by St. Denis in life, and after his death. St. Teresa had glorious visions; and after, in her walks and seclusions, had the company of angels with beautiful countenances and corporeal shapes. In particular, one angel of the order of the Seraphim attended her in times of danger with a flaming sword, to drive back her enemies. Among St. Teresa's other powers was one of no mean importance—the power of delivering souls out of purgatory. Her faith in holy water was great, for by its force she swept away devils as by a mighty river.

St. Hilarian was a match for Satan and his sorcerers. A young man, desperately in love with a lady of rare beauty and chastity, who rejected his advances, applied to certain sorcerers, ministers of the temple of Esculapius. By means of their evil devices the damsel began to love her admirer extravagantly; indeed, so much so, that her emotions savoured more of madness than of true affection. Her parents laid her at St. Hilarian's feet, and he immediately drove out a devil that had taken possession of the maiden, both bodily and mentally. At one time St. Hilarian did what at first seemed invaluable service to the neighbourhood in which he lived. The people besought him to send rain, as their crops were withering away, and their cattle dying of thirst. He sent what they desired, but the rain bred serpents and venomous creatures, which destroyed the fruits of the earth and injured the inhabitants. Like St. Patrick, he drove away the reptiles, and healed the people who had been wounded by them. St. Hilarian also consumed, as with fire, a dragon of enormous size which swallowed oxen, devoured men, and laid waste the country far and near.
