John Cornelius

John Cornelius (Irish: Seán Conchobhar Ó Mathghamhna; 1557 – 4 July 1594) also called Mohun, was an Irish Catholic priest and Jesuit born in Cornwall. He is a Catholic martyr, beatified in 1929.

Life John Cornelius was born John Conor O’Mahony, in 1557 of parents from Gaelic Ireland, at Bodmin, in Cornwall, on the estate of Sir John Arundell of Lanherne. O'Mahony later Latinized his middle name, taking the name John Cornelius. Sir John Arundell took an interest in the boy and arranged for him to come up to Exeter College, Oxford. Cornelius went on to the seminary at Reims, and a little later, on 1 April 1580, entered the English College, Rome, to pursue theological studies. After ordination in 1583, he was sent as a missionary to England and served for nearly ten years, making Arundell's house his base of operations. He was the family's priest and he formed a close relationship particularly with Dorothy Arundell whom he encouraged to become a nun.

While acting as chaplain to Sir John's widow Anne, Lady Arundell, he was arrested on 24 April 1594, at Chideock Castle, by the sheriff of Dorsetshire, having been betrayed by one William Holmes, a servant whom he had reprimanded for bothering one of the maids.

Their trial took place in the main hall of what is now Chideock House Hotel and they were condemned to death on 2 July 1594 and executed in Dorchester two days later. The first to ascend the scaffold was John Carey; he kissed the rope, exclaiming "O precious collar", made a solemn profession of faith and died a valiant death. Before his execution Patrick Salmon exhorted the spectators to embrace the Catholic faith, for which he and his companions were giving their lives. Then followed Thomas Bosgrave, who delivered a stirring address on the truth of his belief. The last to suffer was John Cornelius, who kissed the gallows and then quoted St. Andrew, "O good Cross, long desired", etc. On the ladder, he tried to speak to the multitude, but was prevented. After praying for his executioners and for the welfare of the queen, John Cornelius also was executed. His body was taken down and quartered, his head was nailed to the gibbet but soon removed. All the bodies were retrieved and given a proper burial by Lady Arundell. A fifth man, Hugh Green, who became Chideock's chaplain in 1612, was tried and executed in 1642. All five were beatified on 15 December 1929.
