Saint Donatus is said to be a 2nd-century Roman
soldier and martyr. His parents were named Faustus and Flaminia. When Faustus was deathly ill, his wife Flaminia sought the intercession of
Saint Gervasius, who assured her that her husband would recover and beget a son. This came to pass, and Flaminia named the boy Donatus, which means "gift". She educated him in the
Christian faith. At the age of 17, he enlisted in the famed
12th Legion "Fulminatrix", i.e., the "Thundering Legion". He rapidly rose through the ranks and soon became a personal bodyguard to the emperor,
Marcus Aurelius. In the year 173 the 12th Legion was engaged in the
Marcomannic Wars in
Moravia along the
Danube frontier. According to the contemporary writer
Dio Cassius, part of the legion was surrounded and nearly overwhelmed when it was miraculously saved by a divine thunderstorm. Cassius attributed the thunderstorm to the invocation of
Mercurius by Aurelius'
Egyptian sorcerer,
Arnuphis, but
Tertullian and other Christian writers ascribed the miracle to the prayers of the many Christians in that Legion. Later legend credited Donatus as the leader of the Christians' prayers. After the miracle, Donatus gave thanks to
God, and he was martyred by the emperor. He was buried by his mother in the Catacombs of Saint Agnes. Over the centuries, access to the catacombs was lost. In 1646, the catacombs were re-opened, and the relics of Donatus and many other saints were re-discovered.
Pope Innocent X bequeathed Donatus's relics to the Jesuit church in Muenster Eifel, and they were carried in procession from Rome to the
Rhineland. On 30 June 1652 the relics were at St. Martin's church in
Euskirchen as a
Jesuit priest, Fr. Heerde, was saying mass in the morning. With the conclusion of benediction, lightning struck the church and lit the altar and the priest on fire. He immediately invoked the aid of Saint Donatus and was miraculously restored unharmed. This miracle spread the fame of the Roman martyr throughout the region. Some writers comment on the
alliteration between the
Latin name
Donatus and the
German title
Donner, which means "Thunderer". ==Veneration==
