of Cornwall, Richard Grenville, conducted a raid on Tregian's house during which the crown officers "bounced and beat at the door" to Mayne's chamber. On gaining entry, Grenville discovered a Catholic devotional item, an Agnus Dei, around Mayne's neck, and took him into custody along with his books and papers. Imprisonment and trial While awaiting trial at the circuit assizes in September, Mayne was imprisoned in Launceston Castle. At the opening of the trial on 23 September 1577 there were five counts against him: first, that he had obtained from the Roman See a "faculty" (or bulla), containing absolution of the Queen's subjects; second, that he had published the same at Golden; third, that he had taught the ecclesiastical authority of the pope and denied the queen's ecclesiastical supremacy while in prison; fourth, that he had brought into the kingdom an Agnus Dei (a Lamb of God sealed upon a piece of wax from the Paschal candle blessed by the pope) and delivered it to Francis Tregian; fifth, that he had celebrated Mass. Mayne answered all counts.

On the fourth count, he said that the fact he was wearing an Agnus Dei at the time of his arrest did not establish that he had brought it into the kingdom or delivered it to Tregian. On the fifth count, he said that the presence of a Missal, a chalice, and vestments in his room did not establish that he had said Mass.

Manwood also argued that it was illegal to introduce any papal letter into the country, no matter what it was. The jury found Mayne guilty of high treason on all counts, and accordingly, he was sentenced to be hanged, drawn and quartered. Mayne responded, "Deo gratias". With him had
