Oldcastle, Sir John, Lord Cobham, distinguished himself in arms under Henry IV. in 1411, embraced Lollardism, which he could not be prevailed on to renounce, though remonstrated with by Henry V.; was tried for heresies and committed to the Tower, but escaped to Wales; charged with abetting insurrection on religious grounds, and convicted, his body was hung in chains as a traitor, and in this attitude, as a heretic, burned to death in 1417; he was a zealous disciple of Wiclif, and did much to disseminate his principles.
