Robert Southwell

Robert Southwell, SJ (c. 1561 – 21 February 1595), also Saint Robert Southwell, was an English Catholic priest of the Jesuit Order. He was also an author of Christian poetry in Elizabethan English, and a clandestine missionary in Elizabethan England.
After being arrested and imprisoned in 1592, and intermittently tortured and questioned by priest hunter Sir Richard Topcliffe, Southwell was eventually tried and convicted of high treason against Queen Elizabeth I, but in reality for refusing to take the Oath of Supremacy, renounce his belief in the independence of the English Church from control by the State, and similarly repudiate the authority of the Holy See. On 21 February 1595, Southwell was hanged at Tyburn. In 1970, he was canonised by Pope Paul VI as one of the Forty Martyrs of England and Wales.
He was born at Horsham St Faith, Norfolk, England. Southwell, the youngest of eight children, was brought up in a family of the Norfolk gentry. Despite their Catholic sympathies, the Southwells had profited considerably from King Henry VIII's Suppression of the Monasteries. Robert was the third son of Richard Southwell of Horsham St. Faith's, Norfolk, by his first wife, Bridget, daughter of Sir Roger Copley of Roughway, Sussex. The hymnodist's maternal grandmother was Elizabeth, daughter of Sir William Shelley; Sir Richard Southwell was his paternal grandfather, but his father was born out of wedlock.
