Associated with Prynne was Burton, the author of two sermons _For God and King_, who wrote against Laud and his party, and endeavoured to uphold the authority of Charles, upon which he imagined the bishops were encroaching. Burton suffered the same punishment as Prynne; and Bastwick, a physician, incurred a like sentence on account of his _Letany_, and another work entitled _Apologeticus ad Praesules Anglicanos_, which were written while the author was a prisoner in the Gatehouse of Westminster, and contained a severe attack upon the Laudian party, the High Commission, and the Church of England. He had previously been imprisoned and fined 1,000 pounds for his former works _Elenchus Papisticae Religionis_ and _Flagellum Pontificis_. During this period of severe literary criticism lived John Selden, an author of much industry and varied learning. He was a just, upright, and fearless man, who spoke his mind, upheld what he deemed to be right in the conduct of either King or Parliament, and was one of the best characters in that strange drama of the Great Rebellion. He was the friend and companion of Littleton, the Lord Keeper of the Great Seal, and together they studied the Records, and were expert in the Books of Law, being the greatest antiquaries in the profession. Selden had a great affection for Charles; but the latter was exceedingly enraged because Selden in an able speech in the House of Commons declared the unlawfulness of the Commission of Array, for calling out the Militia in the King's name, founded upon an ancient Act of Parliament in the reign of Henry IV., which Selden said had been repealed. When Lord Falkland wrote a friendly letter to remonstrate with him, he replied courteously and frankly, recapitulating his arguments, and expressing himself equally opposed to the ordinance of the Parliamentarians, who wished to summon the Militia without the authority of the King. With equal impartiality and vigour Selden declared the illegality of this measure, and expected that the Commons would have rejected it, but he found that "they who suffered themselves to be entirely governed by his Reason when those conclusions resulted from it which contributed to their own designs, would not be at all guided by it, or submit to it, when it persuaded that which contradicted and would disappoint those designs." [Footnote: Clarendon's _History of the Rebellion_, vol. i., p. 667.] His work _De Decimis_, in which he tried to prove that the giving of tithes was not ordered by any Divine command, excited much contention, and aroused the animosity of the clergy. In consequence of this in 1621 he was imprisoned, and remained in custody for five years. On the dissolution of Parliament in 1629, being obnoxious to the royal party, he was sent to the Tower, and then confined in a house of correction for pirates. But as a compensation for his injuries in 1647 he received £5,000 from the public purse and became a member of the Long Parliament.
