Turner was descended from a Scottish family, was born at Barnstaple, Devonshire. He was educated for a time at Exeter College, Oxford, and at Christ's College, Cambridge, whence he matriculated in 1567, but left each university without a degree. In after years he said: "Non ego nunc, ut anteà, ætatem meam in nugis Oxonii apud homines hæreseos crimine obstrictos, neque in fabulis domi apud homines nulla politiori literatura excultos, otiosè, turpiter, nequiter contererem". Leaving his country and parents on account of his attachment to the Roman Catholic religion, he went in 1572 to the English College at Douai, where he became professor of rhetoric, and was ordained priest in 1574. In 1576 he went to Rome, and taught the classics for several years in the German College. He states that he was a pupil of Edmund Campion, but whether at Oxford or Rome does not appear. He was never himself, as has been sometimes stated, a member of the Society of Jesus. Turner was for some time prefect of studies at the college of Eichstadt in Bavaria; and, after many journeys and services undertaken for the Roman Catholic cause, he was, by the influence of Cardinal Allen, appointed professor of eloquence and ethics in the Georgian College at Ingolstadt, where he was created D.D. Subsequently he became rector of that university. He was also nominated one of the privy council to William, duke of Bavaria; but, incurring that prince's displeasure, he retired for a time to Paris. A year or two later he returned to Germany, and was made canon of Breslau in Silesia, and afterwards secretary for the Latin tongue to the Archduke Ferdinand, who had an especial esteem for him. He died at Grätz in Styria on 28 Nov. 1599. His friend Pits describes him as "vir in litteris politioribus et philosophia plus quam vulgariter doctus, et in familiari congressu satis superque facetus".
