[Modern Roman Martyrology. The name occurs in no ancient Martyrologies; it owes its insertion to Baronius. His life was written by Everhelm, abbot of Hautmont, his contemporary, in 1069.]
The blessed Poppo, born in Flanders in 978, as a youth served in arms. He made a pilgrimage to the Holy Land, and, on his return, engaged himself to the daughter of his friend Frumhold. When the time of his marriage drew nigh, Poppo mounted his horse one night, together with some retainers, to ride to fetch his bride. He had not gone far before a dazzling flash of light illumined him within, in his soul, and bathed his body in a blaze of glory. As it faded away, he spurred on his horse, and then noticed that a flame burnt on the point of his spear; it was as though he rode bearing a tall church taper in his hand. Astounded at this marvel, he reined in his steed, and turning to his companions said, "God calls me to another life."
Then he left home and went, with the light still illuminating his soul, and served in a hospital for the sick. One day a miserable leper was brought in so covered with sores that he could not be placed with the other inmates. Thinking that the poor creature was cold in the night, Poppo went to him with his own coverlid, and laid it over him. Next morning the leper was whole, the charity of Poppo had healed him. Richard, abbot of Verdun, appointed Poppo to rule the abbey of S. Vedast, which had fallen into scandalous disorder. When the Emperor Henry II. was in the Betawe, between the two branches of the Rhine, Poppo, having to visit him about some affairs concerning his monastery, found the prince enjoying a favourite pastime of his; a naked man was smeared with honey and exposed to bears; and the sport consisted in the bears trying to lick the man, and he eluding their embraces. As this sport not unfrequently ended in the man being injured, and sometimes killed, Poppo rebuked the king, and brought him to a sense of the impropriety of encouraging such coarse and dangerous amusements. That this sport was popular, appears from Hincmar, Archbishop of Rheims, being obliged to forbid his clergy and monks attending either it or bear-bating.
On another occasion, when Poppo was on his way to the Emperor, then at Strasburg, as he passed through the Ellisgau, with some of his monks, they saw a wolf carry off a man by the neck into a marsh. Poppo at once called his monks to the rescue. They were unable, on account of the loose texture of the swamp, to go direct to where the man lay, but they surrounded the marsh, and following the bloody traces, recovered the man, who was much mangled; they bound up his wounds, and he finally recovered. What became of the wolf they saw not, and hoped, and hoping believed, he was smothered in the marsh.
Poppo was afterwards created abbot of Stavelot, where the monks had fallen into grave disorders. His efforts to reform them so irritated some of the worst, that they attempted to poison him, but failed. Having thoroughly reformed the monastery, he rebuilt and beautified the church, and died on the feast of the Conversion of S. Paul, after having received extreme unction from the hands of the abbot Everhelm, who is his biographer.
