sacred well existed, and people drank its spring water only in silence. Willibrord slew the sacred cattle he found there, and baptized three people in the well within a few days of arriving. Willibrord took other mission trips on the Dutch mainland where he witnessed that the people considered clearings in woods, springs and wells sacred to their mythology and religion. Willibrord tried to erase their pagan shrines and landmarks. He built a church in a sacred clearing in the forest, destroyed a sacred forest in Heiloo and renamed heathen wells as Christian wells. Many wells were renamed in his name. In 714, the Frisian King Radboud drove Willibrord and his priests out of the area. Willibrord returned about 719 after the Frankish troops had taken control of the area and the King Radboud had died. Willibrord continued to dismantle pre-Christian sanctuaries. Bonifatius Bonifatius (672–753), also known as Boniface, was the next missionary among the Frisians and Saxons. He arrived on a missionary trip to the Netherlands in 716, specifically going to Dorestad, modern-day Wijk bij Duurstede. When he arrived, Bonifatius found that the Frisians had restored and rebuilt their fana delubrorum, the heathen temples, after Willibrord had been driven out. King Radboud allowed Bonifatius to spread Christian messages but he found the natives had a pantheon of gods and were not that impressed with Christianity. He left the same year. In 719 Rome appointed Bonifatius to convert "the savage people of Germania". Bonifatius joined Willibrord in Utrecht to receive a three-year missionary training, then in 721 travelled east of the Netherlands into Hesse, Germany. Bonifatius undertook a final preaching mission in Friesland in June 753 when he was attacked and killed by a group of Frisians with unknown (legend says resentful) intentions. Saint Eligius One of the best glimpses of late Druidic practices in the Flanders region comes from the Vita Eligii (Life of Saint Eligius) (588 to 660) (written by Saint Ouen). Eligius was the Christian missionary to the people of the Low Countries in the 7th century. Ouen drew together the familiar admonitions of Eligius to the people of Flanders. Eligius in his sermons denounced "pagan customs" that the people followed. In particular, he denounced many Roman deities and Druidic mythological beliefs and objects: "I denounce and contest, that you shall observe no sacrilegious pagan customs. For no cause or infirmity should you consult magicians, diviners, sorcerers
